tech9pc,
I sent the same question to shopjimmy and they said no both part numbers are not compatible and to keep looking for A4.
So I'd rather hear it from someone who's tried it, did 3P55TA004-[B]A0[/B] work well on your westinghouse WG55UR4100​ TV? did you mix [B]A0[/B] & [B]A4[/B] without problems?tech9pc,

Hey again everyone
seems 3P55TA004-A2 is almost impossible to find.
would another part number work? say 3P55TA004-[B]A0 [/B]which seems to be more availableHey again everyone

Thanks a lot. I finally got a the tester from Amazon and got to open the TV. First just with tester, one half of the TV did not show any light with the tester and the other half showed very faint light (probably because the tester current is max 30mA or something). Then when I opened the TV and removed the screen and filters, found 2 out of the 10 strings were not functioning well. 1 completely dead and the other has just 1 worked LED out of the 5 in that string. LED string part number is 3P55TA004-A2. Gotta find out where to get replacement for those two malfunctioning strings.

Re: Westinghouse wg55ur4100 no response

my scenario is a little different, same exact westinghouse model.

After pressing power button to turn on, green LED turned off, with the use of a flashlight i can picture, also i remember i connected a fire TV and played a video on YouTube and there was sound. so I am assuming mainboard is fine, T-CON is fine based on the below readings as well.
Those are the readings I got with all main board cables hooked
