Question about TVs and degaussing.
<< < (2/3) > >>
surf:
I'm using a 27" TV in my cab, and occasionally it will have a lighter tone/color in the middle left of the screen.  Dunno if this is because it's a cheap Wal-Mart TV or what, but usually after turning it on and off again, it works just fine.

I have my subwoofer and computer on the bottom of the cab, about a foot below the TV...

Could just be a cheap TV like mine... :laugh:

NIVO:
how close is your flourescent light to the tv? if you have one that is.
Sensei:
Some televisions (especially RCA ones) have internal interference which can cause anything from color splotches to diaganol lines or washed out areas (as if the brightness were turned up and the contrast turned down....but only in specific areas).  A lot of times it only crops up once the internals have warmed up.  (This may explain why it only sometimes occurs, especially after running for a while).

This is a known problem with specific models or CRT type televisions.

Now if you've gone and done all the troubleshooting you can by removing any electrical/magnetic sources of interference then perhaps you're looking at an internal problem...ie: Surf's answer

Unfortunately, many televisions are sold knowing this is a problem.  In fact many models of televisions have specific repair kits to fix internal interference.  BUT....of course they choose not to fix it unless someone complains.

So it's easy if your television is still under warranty.  Call up a repair shop, give them the make and model of the television and they can tell you if there is a repair kit for it.
If it's not under warranty, I guess you could still do this but it's out of your own pocket.

So if you're baffled and you've done everything you can......

I hope it's on warranty

Just my $0.02 worth.

Good Luck

The TV is a Samsung. Don't know how bad it is.. This can't hurt the TV in the long run can it? I'll play with it tomorrow and see what happens. If it doesn't happen during games though, I'm not going to worry too much about it but I think I might move the power supply just for easier access. I'd say the flourescent light is probably a foot away from the TV. Too close? I'm not sure what to do with that since I can't change the height of the TV or move the light. I may check into repair kits though. The TV is brand new.. Just bought it for this project. Thanks for the help!

I have a similar problem with my 27" Mitsubishi TV using the s-video input.

It seems to be the same as this thread:
