Sliced ​​rolls cost € 0.07, available every day for the price.
Poppy seeds and sesame as well as world champion rolls cost € 0.14
You can say "what does the bread cost?"
However, pricing is the law.
It remains correct in the German language, even if it may sound unusual. But Euro number sounds less good than Voltzahl.
Probably also because volt is used much much much less often than Euro.

Hello everybody,
For weeks now, I've been trying to repair a "Brand" Voltcraft TNG40 laboratory power supply that was given as a defective gift years ago (you have a lot of time at home thanks to Corona).

Yes, I know that I can buy such a power supply from eB * or Am * for around 80 Euro can buy - for me this is a kind of handicraft reminder of my first apprenticeship a few decades ago ...

Symptom: The output voltage can practically not be regulated: Minimum approx. 6.5V, then quickly increasing to 57V. The nominal 40V are reached with a potentiometer setting (R18 (0-47k)) at approx. 3.2k Ohm. The voltage limitation LED lights up continuously; Current limit LED is off.

The relays for switching the secondary coil connections switch correctly (the second circuit board "2226.2" in the device should be ok). The two LEDs D4 and D5 light up slightly; the negative voltage for the OPV is -3.2V and in my opinion it fits. Supply voltages are OK.

I am having problems again with my HAMEG 512-4, which I had for a couple in 2004 Euro and was able to revive it from this forum with the help of perl and high_speed.

Circuit diagrams for this model can be found here:
https://www.sky-messtechnik.de/images/PDFs/HM512-4.pdf

A few weeks ago, after a long break, I used the oscilloscope again. There were problems with the triggering of the 2nd channel. The automatic did not work as usual. I then on the X-circuit board 4 tantalum beads of the Schmidt trigger were measured and after the pins were re-soldered, the automatic triggering of the 2nd channel suddenly worked again. I then ordered and installed 4 new tantalum capacitors.

In the meantime I had bought a Philips function generator with defects on ebay and repaired it (contact bouncer, burnt resistor, on / off switch defective and cracked or brittle switch buttons).

The Aquastop hose to be renewed is then used with approx. 50 Euro rather make up the lion's share.
However, this machine can also be operated without the Aquastop (i.e. with a completely normal inlet hose). After connecting to the water supply, check whether the filling valves are working (start the washing program or the test program). If it works, save yourself all further effort and just continue washing without the Aquastop.

I'm the new one with no plan😂😅

All kidding aside

I have a little problem with one circuit board, you really make me give up 😥

I bought a pc water cooling from the company corsair on eBay classifieds for really little money (it was sold because there was no more flow) I disassembled the pump and cleaned it, so the flow works again
Only a little mishap happened to me while disassembling it
I have it circuit board separated from the coil for the pump
And now I can't get them together anymore

Two extremely short dune wires go up from the coil (I think these need to be attached to the circuit board)
But how do I get them there they are really short
Is there a possibility to somehow extend the wires
(I really have little idea about soldering).

But water cooling now costs 150 Euro would be a shame if this could not be repaired 😥

And yes, so far I've only had to deal with simpler errors where the defective component (diode, transistor, capacitor) could be identified relatively easily.

To your questions: Yes, the potentiometer was turned up during testing. Enclosed the back of the circuit board. The soldering points on the large (largest) capacitor don't look that good - it was changed once - but they are ok.

I checked the connection from the bass to pin 14 and 15 on the IC - it's ok.
The (adjustable) resistance from the potentiometer comes from the circuit board at.

According to the official spare parts list on the Internet (Google helped) it should be 95.00 at Technisat Euro costs.
Several attempts to order the part from Technisat have failed. On the phone you are harshly rejected with the slogans "We only sell to specialist dealers ..." Spare parts companies on the Internet can do that circuit board but not deliver because it is sold out. What to do - besides taking the device to the recycling center? Is it possible to have the codec chip exchanged somewhere? But I think that will jump the budget completely - right?

Hello forum readers,

I have a problem with this heat pump dryer, so far I have been able to isolate the error, i.e. what is defective, only I have problems with the name because the Internet does not know the component.

You have to measure the NTC at different temperatures and receive different measured values ​​(according to the characteristic). An NTC with a static resistance value does not work.

Good Morning all,

I wasn't there when my wife switched on the oven, which caused the interior lighting to break and the fuse to blow.
After switching on the fuse, the stove worked again (without the lamp).
So I bought a lamp and turned it in and ... nothing does not work. Lamp checked, is ok. Voltage measured at the socket, nothing is present.

So the stove was removed and a look at that circuit board shows nothing good.
Diodes are probably burned out.
Attached photos.

It probably has something to do with the lamp, but what can I do to make the lamp work again?

I don't have any (used) online circuit board found ... and ~ 300 Euro (or more) I didn't want to pay if possible.

Thanks for a little input.

Best wishes,

That's why I built in the keypad of the second 704 times.

Yes the circuit board (BOSCH / SIEMENS 00489765) is still available, but you don't really want about 180 Euro spend on it. If the displays are completely dead, the switching regulator IC and the (protective) series resistor from the power supply unit on the control module are usually defective. These parts do not cost 5 EuroIf you are thinking about a used module for the machine, the most important criterion is the exact correspondence of the complete E number of the dispenser device.

After a little thought, you would have to come up with it yourself, because on the circuit board is a processor and it is programmed depending on the machine.
But I also think that many different machines work with the same circuit boards if the connectors serve the same peripherals.

I hope now that through the Oxidized circuit board peripherals are not defective either. since I'm on the circuit board I couldn't find a component myself that was (is) broken, I now hope that I just found nothing and the problem still appears on the circuit board lies.

Hello everybody,

The above mentioned GS suddenly threw my fuse. The device is almost 6 years old.

After removing from the kitchen, dismantling the housing, liquor storage and power module. I already noticed a well-known smell that was confirmed when the power module box was opened.

In the power supply area of ​​the circuit board there was a really nice fireworks display. I think the attached pictures speak for themselves.

As you can see it has a complete trace of it circuit board melted, if not everything is wrong between the HFE8 relay and the coil?

The question now is ... is that repairable? Can I assume that the rest of the GS is still functional or will the damage have shot up other things?

One possibility would be a new power module for approx. 144 in the Siemens spare parts shop Euro to acquire.

Measure NTC, should be in the kΩ range at room temperature and the resistance value must decrease more or less sharply as the temperature increases.
The quickest way to find the heating relay is to track the conductors on the circuit board from the heating module plug to the relay. In order to be able to test the relay reliably, it would be advisable to unsolder it. However, at a unit price of approx. 2 Euro I would not install the old relay again, as it has been in operation for over 8 years.

We decided to repair it after all. As a car mechanic, however, I have to watch out for white goods! Thanks to this forum and many Bauknecht / Wirlpool articles, a new heating element and the associated relay was installed on the circuit board ordered.

My name is Jan, I am 36 years old and a hobby electronics technician. I am someone who likes to repair and not throw it away and buy new. I have been dealing with SMD soldering technology for 3-4 years and have also achieved very good results.

I have recently started working with BGA soldering technology. In addition, I treated myself to an IR station. The device comes from the Far East, but makes a very robust impression. It has 1200 watts (800W bottom heat, 400W top heat) and I think it's fine for my current uses. Of course, I would prefer an Ersa system with automatic placement and an X-ray system, but I don't need to explain why this is out of the question in the hobby area. I now have around 1000 in total Euro invested in the BGA history, including reballing stencils, etc., which is little in the BGA area, if you look at it as a hobby, but is again a lot.

Of course, I have watched countless YouTube videos on the subject and I quickly discovered that it is not as easy as it looks. There are people who repair laptops with hairdryers and the simplest home remedies. But who knows what isn't fake ?!

Hello forum,

First of all, kudos and many thanks to this forum.
Even if it says "just arrived" on the left, I've been reading here for a long time. And this reading caused me a lot of trouble and Euro saves:

- does not heat: circuit board re-soldered to the other pin (why not like this? )
- Water in the floor pan: water pocket cleaned
- does not heat again: relay renewed
- flashes water supply: (searched for a long time, is probably on the corner valve. Have to wait.)
Meanwhile I have a (sad) routine in unscrewing the housing parts.

But now I can't find an answer to my problem using "Search":

The lower the pressure, the fewer the particles to be measured are in the measuring volume, which is of course constant.
The measured value then falls in absolute terms, although the exhaust gas still contains, for example, 5% CO.
The gain is therefore increased somewhat as the pressure decreases.

the solution is there. It was actually the triac. Changed, and lo and behold, everything works again.

Some people told me that it couldn't be the triac because it was still possible to partially control the machine in the far too high speed range. But puff cake.

What I also noticed: the new triac has about 14 MOhm between A1 and A2, the old one only 0.8 - that might have been telltale.

Now I stupidly have all the capacitors on the circuit board reordered and a total of 20 Euro spent that shouldn't have been. Has that been completely nonsensical now, or should I still change them someday?

And as far as the triac is concerned: I've now taken the second "stupid" one that Conrad had in stock, so without a "W".
Would the BTA16-600CW improve something for me?

Uli ...71 - Complete failure - dishwasher Siemens SD6P1S Spare parts for SD6P1S from SIEMENSIs that "only" a double-sided circuit board or is it a multilayer circuit board?
The latter can be recognized by the fact that plated-through holes run from e.g. the top to the bottom into the "void" - i.e. have a connection to a conductor track that is "inside" the sandwich-like structure circuit board lies.

The smoke marks on the condenser and the discoloration of the circuit board lets me guess that there the circuit board has become very warm "from within".
It is very likely that the via on the left from the S2M diode has burned out completely.
Since the "explosion" of a plated-through hole shoots the material "up" out of the hole, there are traces of smoke on the capacitor.
The resulting heat discolors the circuit board material in a red-yellow-brownish color.
This can be seen very well on the first picture https: //forum.electronicwerkstatt.d.....sator.
