About a month ago my Sanyo started developing vertical lines 1 pixel wide. They start at the top and very slowly work their way to the bottom. Will a new TCON board fix this? Any other suggestions?

Hello
Check its power regulator board's soldering points for any loose solderings. Resolder all the suspected solder points by applying a little more solder.

No images only the sound


hi,
You have to check the back light of your lcd TV. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .
ok

Is it true that when one pixel goes out, others are soon to follow?


No, that's not true at all. Each pixel is its only little device - one pixel does not effect another. The pixels work together to make a picture, but are all controlled separately. If your pixel is "stuck" and not dead, then you may be able to fix it! A stuck pixel is red, blue, green or white, while a dead pixel will show up as black. Sometimes a stuck pixel can be fixed by covering a pencil eraser with a cloth and pushing down on the pixel gently while the TV is on. So, in summary - no, one bad pixel doesn't mean any other pixels are bad. Hope that helps, Alex

Hello, a no picture with sound condition can be caused by several things inside your LCD TV. A power supply circuit with a missing voltage source could be one cause of the problem, an inverter circuit or HV circuit could be another. The best answer to your question is to have it checked out by a qualified tech. If you have a little knowledge of electronics you could try to repair it yourself, you can sign up for our great tech support where they can assist you on the steps to take to get it up and running.
