Try to consider the following tips:

Smearing out of one or several colors, best seen in txt-mode, my 27CE4599/30R smeared out in red and green, not in blue, fully exchanging the drivers (input and output complete, otherwise the RGB driver will blank the crt) moved the fault to the other color
Replace the 180K feedback resistors in the amplifiers with normal 1/4W metal film instead of 1/8W, they can become open circuited (in mine both green and red were faulty in this way). Change all 3 and not just the defective ones, replace also all the paralleled 75K resistors per color (fe by 47K+27K) to prevent bright color raster (they can also become open circuit)

Tv comes on but after couple of seconds lights goes off but sound stays ok


check the power board on the 24v side this is for the inverters.if fine then shine a light in one of the side hole in the screen at the back to see if you have a picture if you have a picture then check the relay on the power board is working its a black square there are 2 of them. when you turn on the tv you should hear click then click thats the power and then the inverter power. if you have 3 click that is the inverter power switch turning back off. if you not having this problem. then the 24volt side has a fault. would think off hand the 3 pin power chip its a half moon top. they are prone to over heat if they are next to the transformer. failing that there is a logic power chip 4 pin you will see a white line and the chip is crossing it. hope this helps.

Right half of screen black with thin blue line top to bottom about another line inch over another thin line starting blue then red getting thiner to bottom


This is a very common problem with this Panasonic set where half the right side is bad and the other half is good. This has been traced to a general plasma panel defect in the manufacturing precess. The panel lasts only about 1.5 years and they go bad. The only solution is to replace the plasma panel. The charges for the cost and labor will double the original prize of the TV set.Good luck.

VIZIO P42hd PS42a plasma Picture has two vertical lines (one red/orange, one blue) going down the right-hand side of the screen. Lines are clearly visible


The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.

You have 2 IC's in the convergence circuit and possibly a micro fuse that needs to be replaced. Consult a local TV repair shop.

Top half of screen black


The vertical circuit is going bad,this is the one in charge of opening the picture up and down,try taping on the side to see if the picture reacts ,if it does your set has a loose conection and the vertical IC will need to be resoldered only but if it does not react the IC will have to be replaced,if you are familiar with tv service this will give you a place to start but if you are not be safe and seek the help of a servicer,please let Us know how it goes.
