I have a Samsung LN55C630 LCD 55" TV which started getting intermittent vertical black lines about a year ago. I took the back panel off and through some light troubleshooting determined that it seems to have something to do with a bad contact on one of the chips on the board. Applying pressure to the chip seems to resolve this. I know this isn't a proper fix, but is there any suggested material I can use to apply pressure to this chip? I'm basically asking what can and cannot (or should not) be placed on this chip that won't cause problems or start a fire or something. Cardboard? Electrical tape?
maybe reseating or soldering the chip back into place will fix it.
This would ideal if one has the tools.
Material, yeah, something not heat conducting, like glass, but it really depends what the backing is, what is it pushing against? If the chip gets hot, definitely not something that can burn/melt. Metal is fine, but again what is the backing? so u have 2 surfaces to worry about.
