So my Hitachi Ultravision 42HDS69 42-Inch Plasma has this 3' inch red line that tends to changed colour (from red, yellow, blue, pink, hot pink) and I don't know how to fix it. Any suggestion?

I have a 2 black lines. One goes horizontal and one runs vertical. Is this something I can fix?

SOURCE: Hitachi 50" Ultravision too much yellow, not much blue

First of all sorry for delay.
can you provide a image of yello shadow.I believe it seems to be technically say "ghost image"
If it is ghost image we can try by entering SERVICE Menu and adjust RGB level of the light engine.

Good luck

it you have a repair skills you need to open the TV and make sure all the ribon connectors around the circuit boards are proper connected
and if all seems to be ok, the DG board will need to be replaced.

If you dont have any repair skills I would recommend you to take you TV to a repair shop since this is complex repair

SOURCE: Powers up but picture doesn't appear.

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

I hope I shed some light on the subject for you.
