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.

I have a red stripe across the top off my tv


This issue is because of a defect in the light engine. The only way to solve is to replace the whole light engine. They usually run anywhere from $500-$2500 depending on the model. Sony extended the warranties for the light engine on certain models that have this problem because of the defect, contact Sony to see if a certain TV had the warranty extended.

Red Stripe


the cost of the repair is fair. The color wheel is about 175.00 some other areas in the tv with the kind of problem you are relating can cost the board just above 200.00 until 350.00 then only the color wheel can practically cover the cost you are about to do. Plus labor. make sure they give you the 3 months warranty.

Need more information:
Can you isolate which color is causing the banding?

Hello Adam...

Most likely a bad formatter board, which plugs in vertically on the signal board.
