Not as lucky as I'd hoped, Westinghouse LD-4255VX

I'd seen a lot of the above thread the last few weeks and have been looking to get my hands on a non-working Westinghouse LED. Last night an LD-4255VX with the same symptoms pops up on Craigslist for a price I can deal with. I went and picked it up today. There's a little door on the back to access the mainboard without removing the back. I undid the top ribbon, plugged it in, and tried to power it on. No dice, just a red LED on the front when plugged in. I unplugged it, re-inserted the top ribbon, undid the bottom ribbon, and plugged it back in. Still no dice, still just a solid red LED on front. I pulled the cover off and removed the main board from the TV. I immediately saw the fried IC in the pic below. Ugh, this is a super expensive board. Just my luck

I'll try to get a pic to see if we can read a part number.

It's the HDMI receiver IC... Probably not readily available due to copyright protection. Try removing it: the set will probably work without HDMI.

I'll try it. Thanks

No luck.

You probably had a surge which killed the HDMI and many other components. Tracing down the fault may be next to impossible. New board time, I guess... Sorry...

I may just stick this one under the counter until I can find a replacement board.

Sorry it didn't work out for you, and you probably already know this, but it's a different mobo, different tv than the one in that tread. 42" vs 46"......just saying.

Looks like an entirely different board. Ours have Zoran processors.

The symptoms sound like a Westinghouse monitor that was going to be given to me, but it had a blue LED lit. Just makes me suspect an IC got fried in it too during power trouble in Hudson, Massachusetts.

What's the likely outcome of using the board from a smaller set? No picture?? Mangled picture?? They look identical but there's about a hundred dollar difference in price.

What is the panel in your model? The 26" is:
K260H1-E03 Rev 01

If you have the equivalent, but 42", it should work.

Re: Not as lucky as I'd hoped, Westinghouse LD-4255VX

I will look this evening. Thanks for the reply.

[johnboy1313]

Re: Not as lucky as I'd hoped, Westinghouse LD-4255VX

It looks like my panel may be K420H2-E01 Rev 01

http://www.shopjimmy.com/westinghous...-version-1.htm

Does that sound like an equivalent? I'm still going to open it back up and confirm the panel before I buy anything.

Re: Not as lucky as I'd hoped, Westinghouse LD-4255VX

Is there any T-con on this model?

I can't find any datasheet for the panel. Problem is, one could be e.g. 720p (likely if it is a 26") and this might be 1080p?

[johnboy1313]

Re: Not as lucky as I'd hoped, Westinghouse LD-4255VX

Looks like they're both 1080p. The difference that stands out and will likely prove to be the deal breaker is the 42" is 120Hz while the 26" is only 60Hz.

[tom66]

Re: Not as lucky as I'd hoped, Westinghouse LD-4255VX

That would be the end of it all if the main board has 120Hz output. Does the 42" have a T-con?

[johnboy1313]

Re: Not as lucky as I'd hoped, Westinghouse LD-4255VX

Yeah

[tom66]

Re: Not as lucky as I'd hoped, Westinghouse LD-4255VX

Pic of T-con?

I'm heading home now. I'll get it shortly.
