So lately I noticed when I turn my tv on the picture will have florescent colors here and there in the picture. It'll will go away after sometime but then periodically come back. Does this on both HD channels and on normal. I provided a CRAPPY pic below on what I'm talking about. You can see in upper right that blue color, not suppose to be there, or on the guy's face the yellow, not suppose to be there. Is this a sign of tv on its way out?

 

Is it doing this with everything?  Cable tv?  Do you have anything else connected to it?  It could possibly be the cable box, or HDMI cable - maybe loose or the cable may be going bad.  I would try replacing that first.  

I had a similar problem on a Samsung that was only a couple of years old but out of warranty. The picture looked almost like a color negative. There was something wrong on a small circuit board that plugged into the main board. Got a replacement on Ebay for about $50.

FWIW
YMMV

 

 

ETA...Malsua's post reminded me that it was the Tcon board I replaced.

Cable tv I have only tried, I will have to put a DVD in and see how it goes with that. That's the only thing connected to it. Goes from my ceiling (cable) to the Verizon fios dvr box to tv. I do need to get better cables, been meaning to do this. I'll give the new cables a shot, can't hurt.

Is the TV a few years old? Junk it and buy a new one.

Yes tv is decently old, so getting new isn't a issue...just figured if I can fix by something simple why not

Have you tested with another input?  DVD/etc?

There are essentially 3 boards in most modern TVs.   A mainboard, a power control board and a Tcon board.   There are others, but those are the biggies.

 

If you get no power at all, it's the power control board.

If you get sound and lights, but no picture it's the Tcon board.

Almost every other issue is the mainboard.

Missing pixels or ghosting can be the LCD panel itself, but that's usually due to physical damage.

If yours is an LCD instead of an LED, you can have issues with the backlight inverter board but that's usually just a very dark picture.

You can also have bad banks of LEDs but again, those are just a dark screen. 

 

The most obvious solution here is that there's a problem on your mainboard.    You'll have to look at the model of it, google the board and see if it's worth the risk to buy a replacement.

 

You could install it and not have it fix the issue.  Shrug.

 

Of course, you do need to try alternate inputs, just to make sure the problem is with the TV's hardware.
