How to read it, by connecting jack->usb you mentioned in that post?...

1. I checked i think all caps on tcon, none seems to be shorted, also fuses seems to be ok.
2. I havent checked power supply lines yet, you mean measure voltage on lines from power source board to tcon when tcon is connected to evdd and whe in disconnected?
3. Thanks for warning, by the way evdd is the same as svdd?

By the way on old tcon i found PCB in that area has a bit different color, it looks like it was high temperature there or some liquid: [ATTACH=JSON]{"data-align":"none","data-size":"medium","data-attachmentid&q...

Also im not sure that is important, when everything is connected, apart one of two ribbons from main-board to tcon board, then tv tried to boot with sound, kinda strange

with EVDD from power board to TCON disconnected - "new" TCON, it stops blinking 4 times and i hear the android sounds, once tv boot. Does it mean definitely panel is shorted and the whole TV can be put to thrash only? Apart of selling single parts

I think i got your point, i just saw your post and it was just the first idea, that i got broken tcon from the person who sold me as working, so both can be broken. Although it was mentioned in auction as tested. TCON's seems to be the same' i'll check all details once i got home ie serial numbers etc,...

Hello

I've recently bought broken kd-65a8g with no image issue. Apart of that i bought used tcon ; -). Yesterday i saw this thread but did not start measuring boards yet. TV boots on older tcon, i can hear adnroid sounds, no image, no backlight. Green spots appeares on 0.5-1 second in left and/or right corners once i press power on remote. Oh the new TCON i got only 4 red diode blinks. Any suggestions?
