My toshiba 43xh71 color TV is doing what one of my freinds describes as ghosting. The picture any sub titles and the TV guide are distorted and showing as doubles. I calleed a repair service and they said to unplug it for 25 seconds but that didn't work.

Re: My TV is showing a double picture
If the picture looks like a 3D one, the problem is a convergence issue. This can be as simple as poor connections at the pins of the convergence ICs or defective ICs. If you can solder you can probably fix this yourself. Please note that there are potentially dangerous high voltages inside the set even when unplugged.
If you wish to attempt the repair, please update this and I will provide additional details and instructions.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Technician (only for users in the US for now) and get all the help you need. Goodluck!

If it's picture that's giving a double image from your terrestrial aerial it's called ghosting , you need to move your antenna it's caused by signal reflection and usually happens when your in a strong signal area.
The tv have a problems known as a convergence problems,it dead.The tv have colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures look alike.The tv convergence board have dead 2 STK convergence ICS and some or all it resistors too.These parts on the tv convergence board,must be replaced to solved the tv picture convergence problems.The shop,will cost like $300-350 for parts and labors.

projection sets on occation need to be re-alligned. check your owners manual if you have one and re-align your lamps to the test screen that is displayed when you press 'menu' from your remote or from the front of the tv. This should fix alot of it and you may find the color adjustments may need adjusting after re-aligning your lamps. hope this helps. I had one and that sounds like the 'ghost' images I had till I did this.
Go into your service menu and try to adjust the convergence, if it does not adjust, the IC's ( chips) are bad in that circuit. Call a local factory authorized dealer to service your tv. The cost should run around $450.00. Good luck.
Sounds like your describing convergence ICs. They cost about 10.00 each and you will need to replace both of them. And possibly the resistors that power them total cost under 30 dollars if you do he soldering yourself. Hope this helps.
Can you describe the issue a little more? It may be a convergence issue which is quite common on big screens. But there are quite a few issues that can cause a bad picture.
If it's convergence, you'll be able to tell by going to a news channel and looking at the text. If the convergence is bad you'll see a ghosting like image of 2 or 3 letters for each one that should be there.
Go to the picture control menu and turn the color to minumum so that you are watching a black & white picture. Do this to determine if the color offset affects the overall screen or just the lower corner. If the center is off, go to the convergence adjustment menu and align the red and blue onto the green as described in the owners manual. Some models also allow you to align the outer edges as well. If the bottom is still bad you may have a problem in the convergence circuit. If the outlines are not seriously bowed or distorted a minor convergence toutchup by a qualified technician should correct the problem, otherwise parts are involved and the repair is considered major.
