Hi, cheaper to repair the module than replace it but you should be able to buy one here if you want to, www.wehaveparts.com
good luck and be sure to mark ALL of your cables/plugs as you remove them so you will know where to put them when your ready to install the new module, if you plug something in the wrong place they will NOT warranty the new module, BMW Rider

How do i know if my power supply board is bad


Pluck out your power supply board, from where it is now; and replace it with an other. I think, the location of your power supply will be somewhere between your legs.

Power source does not work. Wont turn on or off


Blown fuse or bad capacitor on the power supply. the set and remove the back panel. Locate the power supply. There is usually a fuse in line with the hot supply wire. Check it for continuity with an ohmmeter. Look for bulging electrolytic capacitors on the power supply. Electrolytics are polarized (+-) and can fail if they go even slightly overvoltage. Replace bad capacitors with components with the same microfarad rating but a slightly higher voltage rating. I.E. replace a 16 volt cap with a 25 volt cap.

Where can I get power supply board (PS 641A352) for Mitsubishi TV model CK-31304 ?


the board is no longer available---in these sets it is find the bad part and replace it, not board replacement. The relay if bad (rare) should have all the info printed right on top of it to locate a replacement.

By the way, if you think its bad because it clicks on and then off---the contrary is the case---if set has a problem relay will turn off.

50 inch lg won't power on


Hi,

The problem could be just a few bad capacitors on the Power Supply, there could be a bad capacitor on the Y board if its bad it needs to be replaced with the buffers together
If you want to attempt the repair yourself you can do a visual of the power board caps will appear swollen on top.
The ones you are looking for are located almost center bottom of the power board,Usually I can see them clearly with the back on simply shining a light into the back through the holes
If otherwise you have to change the whole power supply board Power supply board just die.It can be dead at anytimes.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

I hope this will help in solving the problem...

Standby power no picture


The problem in general (as this question is) would be to inspect the power supply. The power supply board, in the TV will have bad capacitors. You will need an ESR meter to locate and replace bad capacitors. You may look for bulged or skinned caps, if you do not have an ESR meter. If you have an external power supply ( a black electrical box transformer, from ac wall outlet, with another cord that enters the TV) the problem is inside of this. Once again, you will need to replace caps here, thanks for asking and show all hands of support!

Power source out


You will need to inspect the power supply. The chances are real good you have bad capacitors in the power supply. I would estimate there will be 5 capacitors that will be replaced. You may change them all, which is best. Some capacitors will check good when they are not. The power supply will be the smaller of the two boards inside this TV. It is also the easiest to pull out. You may use a capacitor checker to locate the bad caps. This is know as an ESR meter. Once again, it may show a good cap when it may in fact be a bad one. This is rare of course, but I have been there. Please replace all caps in the power supply board. If there is a good capacitor it will be the 400 volt 100Mf (Largest capacitor in the power supply) that is fine! Thanks for asking and show all hands of support.

My toshiba satellite L25-S1193 does not power on at all. Should i replace the power supply. If yes, where is it located.


Most likely either u have a bad motherboard,bad DC jack, or a bad charger. The Toshiba's are notorious for bad DC jacks however they are one of the easiest laptops to replace one on because they arent soldered to the board. Think u need to have a shop run down the exect problem b4 you start replacing parts. Ur power supply on a laptop is the charger cord and or battery they are not like a desktop.

TV does not appear to be powered. Either fuse or power supply


The fuse is in the power supply. It's a slow blow fuse rated 250V 5A.
