Toshiba TV - LCD Screen Issue - Please see video Clip and comment

[culttvguy]

I salvaged this LCD TV because they were going to junk it. I see why they were going to. When I turn it on, half the screen comes on but the other half is all black. Please watch the short clip and let me know what you think. Is the LCD F****d ? Anyone had this happen before? Just want to find out if its worth having it fixed or toss it. Also attached is a pic of the data plate on the back. Thanks for any help !

Feb 2006. Probably not cost effective to fix.

With pretty much all modern electronics, fixing it will cost as much buying a new one. Unless you can fix it yourself. The symptoms it's displaying don't look right, but open it up and look at the capacitors. If they are bulging or leaking you might be able to replace them for a few dollars and get a working TV. For example:

For example:

Electrolytic capacitors are sort of the Achilles' heel of modern electronic equipment. Under localized high operating temperatures (>50°C) they often dry up and die, the fact that they are defective not always obvious (bulging tops, oozing foul electrolyte). It's routine for seasoned electronic professionals to make a beeline for them when repairs need to be made. The YouTube Video is typical of what they would do (and you to pay bucks to them for .
But IMHO culttvguy's problem with his LCD has little to do with capacitors. That defect is more likely to have resulted from the LCD being either roughly handled (or falling from a height). LCD panels are fragile things, and the weakest spot is probably the point where the flat cable from the circuit board is bonded (with adhesive) to the terminals of the transparent conductors on the panel itself. These are very fine (imagine you have to fire up 1920 of them in a row, for example), and when these get detached, there is no way they can be put back. It's just as bad as the LCD panel itself breaking because the TV was dropped. Just tough...
