Hi Guys, I have an old Viewsonic n4785P (aka VS12070-1M) LCD TV built January 2008. It's huge (thick) and doubles as a space heater but it has a nice bright picture and works well as a bedroom TV.
I believe the Tcon board is toast (see https://youtu.be/_fgAEG3_R6k) and I wanted to know how specific of a replacement board do I need to get? For example:
The existing tcon board is a popular V420H1-C07 board that has 3 inductors (some have only 2). The V420H1-C07 is printed on the board.
There is also a sticker along the edge of the board with:
M$35-D020223-L$TSR747400020
I can find many V420H1-C07 boards with 3 inducers pulled from other manufacturers with matching IC numbers as my existing board.
I can also find some V420H1-C07 boards with 3 inducers AND also have a matching M$35-D020223 part of the sticker AND matching IC numbers.
I can not find full V420H1-C07 boards with a full matching sticker.
Do I need to find a full match of board V420H1-C07, 3 inducer version, with matching IC's AND sticker or would any old V420H1-C07 with 3 inducers work?
The only reason I'm waffleing on this is because some boards are ~ $17 and others ~$45 some are locally available in the USA and others are in China.
Anyone familiar with older Tcon boards enough to give me a couple of tips?
Thanks.
