COBY Weird Kludge When Taken Off Fried Main Chip On Board

[Michale32086]

I have never been a fan of COBYs because they are so weirdly designed..

Got this 55" COBY in. The problem was that when powered on, it wouldn't always come on. When it did, the display went wanky, like someone was pushing a bunch of the buttons (VOL, MENU, etc etc) and then would go off by itself, then come back on over and over..

I was thinking a wanky MAIN board, but when I cracked it open, I noticed a weird "kludge"...

As pictured, on the back of the MAIN board and smaller (Driver??) board, there was a 2 strand wire that went from 4 pins on the LVDS connector on the MAIN board to corresponding 4 pins on the LVDS Connector on the Driver?? board...

Thinking that may have been the problem, I disconnected the wires and the main chip on the DRIVER?? board fried...

I ordered a new DRIVER board, but am unsure if I should try it without the kludge or not..

Any suggestions??

I should also note that, on the replacement DRIVER?? board, that set of 4 pins are NOT jumper'ed together...

The last pic shows the white cable and to me that does not look like a factory installed wire. It would appear to me that this TV was repaired before and some 'bypass' surgery was performed.

Yep, that's my guess as well..

I just don't know if removing it is what caused the big chip on the DRIVER board to fry or not..

The board is cheap, so I spose I could try it.. I have a 50/50 chance Fry or NO Fry

If it was working before with it there, I would leave it and give the new board a try. Is either it works or it doesn't.

Yea, that's my thinking as well...

Thanx.. Let ya know in a few..

Hooked it all up and powered up.. Nothing. No LED, no nuttin..

I was getting voltage on the MAIN board so I looked deeper..

Looks like a component next to the LVDS connector on the MAIN board got fried as well..

Ordering a new MAIN....

Will update..

Thanx again for the replies..

I have a bad feeling about this TV. Especially when it appeared worked on before. Sure you want to spent on it again?

Yea, it's only another $40.. it's a nice 55"...

Putting about $70 into it is not too bad, considering I can probably get around $250-$300 in my area...
