I have a 2 year old th45pc77u. Recently I noticed a blue/green 3" wide transparent veritical bar about 3" from the left edge of picture. I have satellite service. Is there a fix?

My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further updates will be on my Facebook page.

Important Warranty Announcement for LCD TV Owners

It is probably the main total assy needs to be replaced.

Cover green CRT lens with towel and see if red/blue video is normal......= bad CRT ?.............................T.

PiP or bad connection. disconnect the set with all cables and reconnect and see what happens

I have a similar problem, what is the fix?

Greenish yellow spot only means one thing. You have a defective lite engine. The only fix is to replace the engine. This part is very
expensive. Average cost $835.00 Part number A-1606-008-A

Sounds like the veritical circuit has a bad capacitor. The cost is dependent on the servicers in your area. It can also be dependent on whether you take it to the shop or have a servicer come to your home. Look on a Mitsubishi website to find a servicer in your area.

Your set is starting to get a convergence problem and the only way to repair it is by changing the convergence IC's,(3)one for each color,the blue migh be showing more now but soon all 3 colors will be out of alignment and you will not be able to correct it with the custumer controls,is great that it has worked for so long without this problem,if you are familiar with tv service you have a place to check but if you are not too familiar be safe and call for help from a pro-servicer.Let Us know how it goes.
