SOURCE: after warming up the picture

It flickers because the tension to the plasma panel isn't stable - the power source is faulty. You must open the tv and check the source, the Y and Z boards for failing parts (especially the capacitors).  Also look for loose connectors, bad solderings or bad wires.

SOURCE: 46in Vizio LCD HDTV distorted black picture when tv is turned on

Hi There are three things that can cause this problem. Your lcd screen, t-con board or the signal board. Most likelly in your case since you say it's only half the screen it's going to be your t-con board. You can try removing it and cleaning all the contacts and replacing it see if that helps. If that doesn't help then replace it. If that does not solve it then it's going to be your screen.

White horizontal lines covering picture on Toshiba 51HC85


The set uses a Hyper board inside that processes all signals, it is well known for this issue, board no longer available=reason is quite simple : about a dozen tiny surface mounted filter caps on that board with age dry out, at first it will work after warms up as poor caps regain some capacitance and seem to be ok.

Buy a new set, you can send that board out and have it repaired/rebuilt but the last one I saw which was under extended warranty cost about 200 just for the board rebuild.

In the last 4 years Here on Fixya I have encountered only 2 people who were able with instructions had the skill to remove the board and replace those caps, both were top notch computer repair techs.

TV picture is unstable until the TV warms up. This is taking longer and longer. Picture gets large, small, large, small... Quality is also lacking until it is warmed up. This is a Phillips 60'' Is this...


What model and brand is your television?
Is it a CRT type or DLP?
If picture is getting smaller then larger, and its a crt rear projection television sound like you have bad connections around the Flyback transformer and or horizontal circuits. This usually happens when a connection is made on the circuit board and the picture returns to normal especially during a cold start, but as the television warms up the connections on the board start to seperate and the problem starts occuring or it could be in the reverse process. Unstable at first then when tv gets warm it make better connections. All in all have a technician check the HV section of your deflection board.

Blurred picture, after some warm-up it back to clear picture


If the problem doesn't return after the picture becomes normal, then it could just be due to the electron gun taking longer to fire up. I don't know how old your TV is, but TVs older than ten years typically take longer to warm up than more modern sets.

Picture won't come in clear until TV "warms up" for 15 minutes or more


Change the capacitors first per the instructions in the link below. Symptoms could be anything from high-pitched hum to no picture at all. On these defective models, I would start at the caps and work back. It won't hurt to replace them anyway.
