It is a plasma so the screen will be OK, the white balance requires adjusting in the main menu.
Plasma Screen have no tolerance with pixels that are out. If faulty in the factory, they are switched off but only if they are not in the centre portion of the screen, otherwise the screen is scrapped.

You need to adjust the panel voltages, adjust the VS voltage to around 186 volts, if that doesn't change it then adjust the V-Scan voltage down, turn the unit on and apply a video source to it, and while adjusting the voltages look at the screen and you should be abe to watch the video noise fade out.

SOURCE: red pixels

you will need a professional to service your tv. basically the tech needs to  connect an osciliscope to the y susatain board and adjust the voltages on this board. most plasma tvs will need this done about every seven years because electronic components tend to lose their value over time. this is called electronic drift.

SOURCE: Toshiba 65H81 blank screen and red blinking light....help

I had the red blinking light problem on a toshiba 55s rear projection. It happens once in a while 6 mos ago, but gradually shutsdown after 45 sec or so lately. search the net and found www.casias.com repair log. typical hunch on convergence ic or power supply problem. Decided to replace convergence ic bought at Suburban Electronic Wholesalers ebay store ($15 for 2pcs of STK392-110 ICs). Removed the board at the back 9 screws and wirings (make sure to mark it). removed a electronic board (soldered) that hinders access to the ICs and removed/replaced ICs. You can go to casias.com for actualy pix. And voila!! my TV is now back to normal... I would say if nothing is physically wrong with your motherboard (fuses, etc.) most of the time it is the convergence IC. It doesnt cost much.. so start from there..

Red shadow around every image


call up the menu and look to see if words have red or 3d effect---if this is so, suspect you have a convergence problem; the set should also have a option for adjusting the convergence---some just give you a cross in the middle of the screen---if red or blue will not adjust either up/down--left/right you have a bad convergence IC----The Hitachi sets all use two IC's and Usually this repair can be done in your home----I do a lot of them here in the San Diego area where I live----have done over a hundred in the last year on all brands of sets. If you know someone who knows how to solder etc, you can (get me model number) buy both the convergence IC's on Ebay for under 15 dollars plus shipping; some internet places offer a kit with the IC and whatever other parts might be needed; usually this is a waste as most of the time only the IC's and maybe one or two resistors around them are gone.

Maganvox TV with red-shadow to picture


Hi Emily,

Your TV has bad convergence amplifiers. They are large integrated circuits that are mounted on large metal heat sinks. They have a part number on them, but might be covered up by a bracket. The part number should start with STK. They are replaced as pairs. You will have to find someone with the skills necessary to replace them.

Best Regards,

Not sure, but looks like blue and red shadows around words on the screen


Al, bring up your convergence grid (look in menu for it) and I think you`ll find that the set is out of convergence, if you can adjust the red up & down and the blue up & down your ok, if they won`t move in one or both directions the convergence IC`s will have to be changed out, hope this helps, BMW Rider

Blue and red shadows on screen


This sounds like one of the convergence IC's has cracked loose or burned out, and should be replaced and realigned by someone with experience.
