    If you keep replacing power boards it could be you are getting surged. Buy a power surge protector. If you already have one, how long do these boards last before they go bad? Also, if you are buying these boards from same seller, I would try someone else, they may be selling you faulty boards? These are just some ideas! One last thing, if you know how to solder, you can probably fix these boards yourself, look for bulged caps, on board, they are easy to replace and are cheaper then buying new boards.

SOURCE: blackout problems

It could be the LVDS cable that is connected between the logic main board and the main board, sometimes this cable is too short and comes loose from one of the boards, it could also be a sign that the logic main is going out or the panel itself is shorting out

SOURCE: prolonged washer cycle time

Hi! I'm not familiar with this model, but it sounds to me like there is not a problem! If you set the delay time to 0H, switch off the unit at the main switch, then switch back on. If there is still a 2H displayed, it means that the PROGRAM that you have selected will take 2hours! This is fairly common for the Bosch units on the 50 - 65degC cycles...some models have a "reduced washing time" button - it looks similar to the "delay" symbol, but once pressed, it reduces the washing time by almost half (cuts on rinse cycles) If your model does not have a reduced time button, select a shorter cycle (35/40/50eco), and see if the time is less. Remember that the latest dishwashers are engineered to be more energy efficient and water wise, so they had to lengthen the wash cycles in order to get good wash results! Hope this helps! C.

SOURCE: Samsung plasma all black screen

Black Screen come from three areas. 1- Power Supply Board 2- Inverter Board 3- Processing Board on the LCD. Since the Power Supply Board was replace, it easy to troubleshoot where the problem. lies If you cannot get the backlight, then its the inverter board. If you can use a flash light on the TV screen and can barely see the images, then the problem is indeed the inverter board. If you cannot see any images when using a flash light, then the problem comes from the LCD processing board. Let me know if you have any success. Mike

SOURCE: samsung 42' plasma tv,screen keep flashing, blurry,no pics

I'm not really sure what causes this but I might be able to help.
I have an LG 42 plasma which had the same problem. In my case I removed the video and the tuner board (they both were mounted on the same frame which was screwed on the tv chassis) and installed them in a "wooden box" so that there would be no electrical contact with the rest of the chassis except from the cables connected to them. It now works fine.

Back - light inverter problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Why would a samsung plasma tv have no power no stand by light does not make a sound


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Sony Wega Plasma 42XS955. Over 2 wks., gradually


I would check the capicitors on the power supply to see if the they are bulging at the top or leaking. I had a Samsung lcd that starting taking and hour to turn on then eventually it would not turn on. So I checked the power supply and saw four bulging capacitors that I replaced and now it's working like new.

The most likely issue is that the Power Supply has burnt out, you were able to let it cool at get it to work for a while, but perhaps part of the board has melted enough to cause a short. Repairs will cost approx. $300-500.

Need more info on the unit.
Model, Serial # and Version # on side of unit. It sounds like you either have powersupply problems or cold solder joints in the power supply. Resoldering board may solve your problems.
Let me know, Have a good day. Jay
