    the marks are two small lines which start at the top of the tv screen and go down towards the center of the screen. they are about three maybey four inches long and one is shorter than the other, but they are side by side.

My 96 cadillac deville's cluster will not work.the fuses are good,its only the middle where the mileage and fuel lights are.


There is a backlight bulb that is burned. You will have to remove the cluster and replace the bulb in the middle. I can't remember the exact bulb number but the old one should have a marking on it. I would suggest replacing ALL the bulbs (I think there are 3 or 4) as long as you have the dash out. They will all burn out shortly due to the age of the vehicle. Bulbs are good for about 10,000 hours or so.

Good Luck.

3 round dots on screen yellow red blue


I have to be honest with you, I suspect the marks are burns on the three picture tubes and permanent.

A simple way to prove this that requires no technical knowledge:

Remove the back cover and locate the three large lens (red, green and blue tubes) and with the set on cover each lens one at a time; if a mark vanishes that tube is burnt in the middle.

If you have three dots or tear shaped marks the set arced and burnt a small area of each picture tube's screen.

These tubes are about 4x5 inches at the screen and are like a regular tv screen; there is a phospher coating and if the set arcs it will burn the coating away in the middle of the screen on each tube.

Confirm this and if true two things would have to happen: replace all three tubes (not worthwhile) and find what caused the arc.

I do not like to give people bad news but I am honest and if this input helped or informed you give this solution a "very helpful" rating as I do this here for free.


If you have ANY questions or need advice do not hesitate to post a comment here and I will respond.

Rca scenium 52" has light bar area down each side


I take it that you have watched many hours of 4x3 video on this 16x9 TV . What you see is evidence of screen burn, like they used to warn about with the old "pong" type games with stationary objects. The 4x3 pattern is burned into the phosphor in the projection tubes. the area of the burned pattern is not as efficient as the unused areas that make up the 16x9. If you watch enough 16x9 it may even out somewhat, but will never be perfect. Replacing the tubes will fix it, but they're pricey, and you may be subject to it happening again, depending on your viewing habits.

Burned out brake light (middle top light)


Take a putty knife and slide it under the front of the cover to release it from the area behind the back seat and pull it forward. Then twist the bulb holder out of the cover. The bulb pulls out of the holder . Replace bulb and reassemble.

Red color trouble


A picture or blank raster viewed from the front will have red marks if a portion of the image path from the green CRT to the front screen is blocked by debris or if the Green CRT is damaged from burn-in or other situations. If green is missing, red dominates virtually any image.

Severe CRT burn-in can occur when there is no sweep signal to a yoke. I have seen technicians removing yoke connectors on RPTVs in attempts to find shorted or suspect components.

Occasionally a damaged TV is sent back to customers as repaired and a service order for a new "fault or complaint" is initiated when the customer complains of the red or green marks or lines.

Red spot in the middle of the screen


You most likely have a burn in on the surface of one of the picture tubes. What you need to do to confirm this, would be to take off the front screen, and with the set turned on, look directly into each one of the lenses, and see if you see a mark on the green or the blue tube. if this is the case, and I am pretty sure it is, the picture tube will need to be replaced, but this set is not a young thing, as the green faint lines is most likely a bad capacitor in the screen drive circuit. If the picture tube is indeed burned on the surface, most likely be better off buying a new TV set. Good Luck
