Re: 42" Vizio No Picture has Backlight

Got the new/used T-Con board today, got it installed and everything works good...on High Definition Cable TV using HDMI input. I'm So happy to get it going.

Now another project.... I just got a 47" Philips LCD from a guy for free, he said it went out in a thunder storm and that he himself replaced the power supply board but still a dead tv, I will start a new thread on it once I get into it, haven't even taken the back off yet.

I want to thank Budm and everyone else that helped me on this one.

Thanks so much!!!!

Fixed 1 Plasma and 2 LCD TV's so far.

Whew! I am glad you got it fixed, $55 for 42" 3D TV, not bad. I hope the EEPROM does not go out next!
By the way, can I get good picture shot of the T-CON board, and do you mind if I post your pictures on my Photobucket so it may help other people also?

Re: 42" Vizio No Picture has Backlight

I actually bought this tv not working for $150 paid $55 for T-CON = $205 total investment.still a great deal. Attached is a picture of the T-CON Board, I guess I could have removed the metal shielding to try and troubleshoot but It may have been a bad processor IC that I wouldn't have been able to replace anyway, hard to tell what failed on this board. one guy posted he did a re-flow with a heat gun on a few TV's he fixed. I think I will hang on to the old board anyway. Bud yes please post in your photo bucket to help others. Thanks!

yes that was an expensive bugger to fix for me I think it required new psu and a tcon board for me to fix that one... Good luck.

Did you ever get the T-Con? Was that the issue.


Have the same issue and getting the light sequence. Checked a few caps on mainboard and all are good. Not sure where to go from here customer had already replaced the video board with no results.
