Orange tint too screen

To know what is wrong do a simple test almost anyone can do

Model listed has three picture tubes, with rear cover removed turn set on and look into the three lens, each should have a picture--one red, one green and one blue.

If any one of the three look like a floodlight you have bad glycol in that tube.

This will not be a do it yourself repair, The liquid is toxic and like antifreeze to keep the face of each tube cool.

Do not attempt to take the lens of the affected tube apart, that can be fatal to you and the set.

Let me know what you find and I can give you options.

I have a rca tv model #27v5137 that only has the bottom picture displayed. Does anyone know what is wrong with the tube?

It is not the picture tube but is a vertical deflection problem. Usually it is a capacitor C246 and this is the location number and is a .47mf And at the same token bad solder connections on the pins of the vertical deflection IC301. Soldering the pins of IC301 is likely to fix the set.

How do you clean a vs5046 projection tv it has a dark picture or does anyone know where to download the manual production date feb 1997 serial #007286

This TV is probably finished. The picture tubes don't normally last more than 8 or so years with normal use. The back cover is easy to remove on most projos (power OFF!!). The picture tubes can be cleaned with a damp cloth like a chamois. Don't handle the mirror. The silver is on the wiping side - you will destroy it! Stay out of the electronics! Safety hazard.

Neon in color

sounds like you might need a good cleaning or your tv has contaminated coolant in the picture tubes. or you just might need to adjust the screen control for the picture tubes.

Toshiba 32A41 TV -- color problem

Toshibas are notorious for developing shorts in the inernal guns of the picture tube. In your case the green gun is shorted to G1. The noise you heard was an internal arc between the elements. It is unfortunate however, the repair of this problem usually requires the picture tube to be replaced. Sometimes a savvy technician with sencore picture tube rejuvenator can remove the short. This however usually does not last. Scrivitron
