42'' Hitachi Plasma TV has developed pale red vertical line that appears and disappears randomly. Occurs on cable programming and DVD's.
Line will appear in different parts of the screen and is about 3'' wide. It remains when you change the channel, turn off/on and if you unplug the set. It goes away as randomly as it comes.
TV is 3 years old.

If the set is still in warranty, call for warranty service. If not and you feel comfortable working on the set, carefully open up the back and reseat all of hte cables and connectors. This can be caused by marginal connections inside the set.
Keep us posted on your progress and results.

My thought is that it is an Intergrated Circuit (IC). But it has been brought to my attention that it may be as simple as adding a "ground adapter" to the plug of the TV. If after you try changing out the ground adapter and it doesn't work, try "power cycling" your TV. (unpluging it... Waiting 30 seconds, then plug it back in.) If that fails, contact Hitachi so they can recommend an authorized service center in your area. Hope this helps. Good luck, KMarshall!

Did this fix your issue? I have the same issue with this model. If so, was it very expensive?

We originally had a red stripe roughly 3" wide running vertically on the ride edge area of our Panasonic 52" Viera plasma tv. It has now been joined by a solid black stripe of the same width running from the top to the bottom. Living in Germany and purchased at local PX long enough ago that the warranty is likely expired. Now what?
