Re: Westinghouse LD3255VX Main Board eBay replacement.



I was wondering this. The datasheet shows a pin33 / gnd which appears to be a metal pad on the bottom of the 34844. I swear they make these boards sooo freaking hard to fix without destroying the board that you have to be pretty dedicated at saving this $40.00 TV.. It truly HAS to be a labor of love, because there isn't any money in it for sure.

I only paid 25 bucks for the board with free shipping. It was listed for 55 bucks, but the description said minor cosmetic problems, so I offered 25...

Re: Westinghouse LD3255VX Main Board eBay replacement.



The C board is the only one showing ANY signs of life. The old board is a dead short to the PS, and the 19.2 VDC drops to millivolts when I plug in the old board. My original post was made after I had already installed the C board, but had no back-light.
I did notice the other day that the back-light is working on the left side of the display briefly (flickers for a few seconds, then dies and the voltage on D21 cathode slowly drops to 19-24 VDC) It appears the TV has to be plugged in for a few minutes before...

Re: Westinghouse LD3255VX Main Board eBay replacement.

Thanks to everyone for the replies. I did try several times to call Electro parts to ask if the A and C boards will interchange, but not once had anyone answer, nor return my calls. Of course in this day and age of scam after scam phone calls, and google voice telemarketers, if no message is left, any call returned may be shrugged off as another identity theft scammer. 6 freakin calls TODAY! <sigh>
From my understanding from reading the thread that Kg74 has on the same TV, it's my understanding that the eprom software...

Thanks for the reply, Bud. I had already seen the cautions on SJ with all of the google searching I have been doing on this board.

All of the connectors and ribbon cables seem to plug in properly. The front red indicator comes on as it should with the new board, but no back light LED's or visible picture. I can't seem to find a pic using a flashlight either, but it has marginal batteries, so am unsure there.

I haven't probed it very much, but at first checks, I am getting 19.2 VDC...

I need some advice on a main board replacement for a Westinghouse LD3255VX 32" LED tv set. It was totally dead when I got it. No signs of life whatsoever. After googling it, and no luck on the problem even close with the exception of bad caps forum, I feel that this might be the best place to ask this question.
I bought a replacement board for this TV off of eBay, and did not even notice until I hit the "buy it now" button that there are 3 different boards for this model of TV. duh~
Anyhow the listing states that I may have purchased the wrong board for this TV since...

Hi fellow electronics enthusiasts! Just a quick intro. I am a SWM located in the St. louis area, and am into most anything and everything mechanical / electrical. I am a actually a Licensed Electrical Contractor, but only because TV / VCR repair never did pay the bills worth a darn.
