There are vertical 1" to 2" black lines that come and go. They are on the top half of the screen only. Also, the TV takes 40 min of flashing before the picture comes on. Our TV is about 5 years old. ...

Vertical lines down center of Plasma TV


Because of the complexity of these sets, the fault can be much more than just a bad IC. These sets are serviced at the board level. After changing the board, calibration is done as necessary.

The fault may be in the matrix power driver output area, or in the plasma screen back-plane layer itself. This has to be determined by the process of elimination.

I can tell you in advance that this will not be a low cost repair.

Hitachi 42EDT41 plasma model-1" black stripe on right side


This is an old post but maybe it will help others. You will have to take the back off of the TV. On the bottom you will see ribbon cables coming from the screen and connecting to 3 PC boards. Take the screws out that holds the cable down. Underneath you will see 4 resistors marked 100. All you have to do is re-solder the resistors and your vertical line will be gone. You need to be good at soldering or you could damage the ribbon. The only ones that you have to re-solder is the ones in line with the lines on the screen.

Vertical black line on screen


Your set has either a bad driver board or more likely a bad plasma panel.

Blue/black vertical line in the middle of screen


Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

Mitsubishi WS-65511 Rear Projection Big Box TV resets with a green flashing light every 5 minutes, Then works fine for 5 more minutes (perfect picture). Acts up worse when cold. Warm it up Works hours It's NOT the DM board caps. I've already replaced the DM caps twice. Not the problem. No repairman will look at the set. Too Old. So am I. I could repair it with help. The power supply must have a safety circuit that will shut down & reset if too much draw. I DON'T have a diagram. I'm not sure how to trace it . Which board? If I unplug boards one at a time, Will it damage other boards ? I know it is NOT the 7 DM board caps everyone keeps telling me. I see no burn't parts, No bulging caps. Tapping on components doesn't reset. What kind of component would act up when cold , But not overdraw when warm? This set has the best beautiful picture when it runs. If you can get past the resetting every 5 minutes for the first hour, You can watch it sometimes for 20 hours. I've left it on at night & it is still on the next morning. Change the channel Or raise the volume, And off it goes. Once or 10 times, Keeps resetting. Then on for 4 or more hours, Maybe. I can't afford a new one. It works GREAT ! when it works. I've notice that even when the set is turned off, The green light starts flashing (resetting itself while it's off) , Then stops. Once in a hundred times it will kick off the breaker & you need to push reset with a pin on the front panel next to the green light. It's probably a 10 cent resistor OR a $ 1.00 cap. If I only had someone with more knowledge than me to help. I know how to use a meter & read a schematic. I built a Heathkit 25"TV in the 70's & all my novice ham gear. I'm 64 & not familiar with digital circuits. Can someone help PLEASE ?
