Answers :

This problem is not easily to be solved.Tries to changes all the capacitors components even if u think is good around the bad capacitors surrounding area.After that,if u still have the same problems.This problem could be any high voltage components parts like transformers to ICS power regulator.Trying to fix this power supply board probably beyond your ability and u must also have the tv power supply board original schematic and electron scope too . .To measure those power transformers and ics power regulator output.Tries websites like Shopjimmy.com,EBay.com to buy a whole new refurbish tv power supply board for the replacement that is ur best bet.

I have a Vizio VP42 HDTV (inside says LG PDP42X3U400). One day I turned on the TV and heard a pop. I took off the back of the TV and inspected the main power supply board (P/N 6709900019A).

I think I shorted out the power supply board on my Onkyo HT-R667. I was replacing some the capacitors to repair a hdmi switching issue. I was testing the repair with the top cover off. While it was powered on I accidentally touched the metal top to the top of the power supply board CMKM-P3X. There was a spark and the unit turned off. It won't turn back on. No lights. Can it be fixed or can I purchase a replacement board if this is even the issue. Thanks

Dynex 47 My Dynex TV stopped powering on. I was told it could be the power supply board cause the indicator light was not on red or turning green when you tried to turn the TV on. I installed a new power supply board, and i'm still not getting any picture or light indicator. What else could the problem be?


This is exactly why I tell people that when your set isn't working, you have to have it properly diagnosed. Chances are you have a defective main board. The power indication is an indication that you have standby power. However, the power indicator i ... Flat Panel Televisions

Heard a popping sound unit turned off power light blinks four times. Replaced power supply board, power supply board now blinks ten times and unit will not turn on.


10 blinks on this set is not a power supply fault but rather an A-board fault(Main A/V board). Hence replacing power supply would not do the trick. I suggest you return the board and get an A-board for +50$ and I am confident that it will resolve you ... Panasonic TCP50G25 50 in. TV

I own a DYNEX DXLCD37-09. I am having trouble turning it on. The red "STAND BY" indicator is on and when I press the power button the green "POWER ON" indicator flashes a few times and then instantaneously turns off. My question being, is the problem the power supply board or the inverter board?


It can be related to a power supply fault , problem in the SMPS unit. Also a poor connection due to dry soldering of the drivers cannot be ruled out and so if you tap the TV while it is powering and if the power comes up it can be a poor connection. ... Dynex DX-LCD37 TV
