Replace the convergence board about 100.00 for the board and you have to know what you are doing to remove the old one and put the new one in

Did you check the two pico fuses on the G board? Usually at least one will blow when the original ICs failed. I am attaching a pic that shows the 2 pico fuses on the G board.

I have a glow or a shadow around everything I watch...I tried the converse blue but i dont know if i did it right bc it didnt work...how can I fix that?


CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Why does my TV have a red shadow on all the people and words. i've only had it 4 1/2 yrs


It sounds like the red gun is off. Your tv uses three guns(red,green and blue) to make the picture. sometimes one of these guns shifts a little and the colors get messed up and there are shadows because the gun is still trying to make the image, it just doesnt line up. This is a pretty inexpensive problem that can be fixed by most any tv technician for a small fee. If your pretty confident in your electronics know how, google adjusting guns and your tv and that should yield something.

Blue shadows/ghosts


how old is the tv ??
if this tv is older than 5 years it may need to refill the liquid on the proyection bulbs and/or could have contaminats in the fluid causing the ghost and to fix that you will need a professional person to do it

Problems with my Mitsubishi hd1080


If the Blue lines are blurs or shadows, then your Convergence IC's are going or gone bad.
I have the same TV - it will be 4yrs. old in Dec. Mine started with Blue lines & shadows, then Red, Blue, Green Shadows. This is caused from over heating. The Convergence IC's have to be replaced.
I have had 3 TV Repair shops all quote me a price from $350. to $400. to repair. They all said 4 years is the usual life time for these IC's.
Replace the STK932-110amps with STK394-250-E or STK392-150 for greater reliability.
Use only Original Replacement Parts, there are some cheaper but won't last and can't take the heat.
If you are a "do-it-yourselfer" here is a link with the directions and pics.
