I have a Philips Flat TV - HDTV model number 42PF94310/378 My problem is, now when I turn in on there is approximately 3-4" black vertical line going up the screen (near the center of the screen). I'm decent with fixing technical problems on computers etc, but I don't really know much with televisions and what could be causing this problem. Should I take it in for repair, or is there something i can replace fairly easily?

Thanks for your help!

That looks like something to do with a buffer board. Maybe that certain part of the board has had it, or ribbon failure or loose connection.

Im the same as you, more into PC repair, not really touched tellys but im here because im also having problems. Very Happy

Have a watch of this, might give you some idea about the fault finding.

With my telly ive got a buffer board on the side, and one on the bottom, some have them on the top and bottom etc. They are a long strip like board with ribbons connected to it, it will be something to do with the connection/board directly where the line is on your screen.

Alright, Im 90% sure Ive found the problem and a new board would not be the solution.

While removing the ribbon that coorilated to the black bar on the screen I found that some of the wires within the ribbon have become exposed and broken causing the short. Now the bad thing is it looks like the other side of this ribbon is connected to the panel itself. Any know how there would be a way to repair?

I included some images, sorry if the quality is poor.

Any advice would be great. Thanks!

EDIT:

For the close shot, if you look to the right of where my finger is pointing, you can somewhat see the thick black line on the ribbon running up and diagonal. In the middle or so the wire starts to extrude out of that black line. Really hard to see on this close of a shot.

Not good news i dont think. Most flat screen tellys are like you said, with the ribbon built into the panel. So you cant just replace them, its either a new panel which is costly, or the only other thing is try and repair/bodge the ribbon.

I really dont think that the ribbon is recoverable. Do you know a way to repair/bodge/mickey mouse the ribbon?

Not to ask to many questions, any idea where i should look for fair priced replacement panels for this television?

EDIT

I found the panel, it looks to be approx 160$.
