If the set has three picture tubes it is usually done from the rear (safe and easy) by simply cleaning the lens above each tube. Got a model number?

Yes you can safely clean tv, just remove front speaker panel and you should see screws holding up front prot. screen. Becareful not to snap screws. You can take screen out and there is a mirror that you can clean and 3 lenses.

You will have to do some dissassembling of the cabinet to remove the screen and bezel assembly. If you are will to do this I can give you the directions.

If you want to adjust focus and screen there is a focus block some sets they can be found on the front behind the gril then behind a cut out held in place by screws if not check from the rear. But a ghost like you say sounds like a convergence problem

SOURCE: I have a RCA 60 inch TV and its about 12 or 13

you probably have a little of both. the shutting off is definately heat related but could be too much dust on heatsinks, etc causing it to shutdown. cleaning may eliminate problem but could be a sign of an underlying issue..
the dust can really cause the picture to dim. most of these tvs you can pull the "lightbox" or guts out of the cabinet to clean all 3 lenses, and clean the mirror if needed. don't mess with the screens except cleaning the front from outside. usually a 1/4" driver will be all you need, and a soft cloth for the lenses. use compressed air or a vacuum to clean out dust which will help with cooling, but the picture is only effected by dust on lenses, mirror, and screens.

My mitsubichi projection tv model vs-50605 is getting dark, Do i need to change the bulb


This model does not use a "bulb", it has three picture tubes.

What does happen is the lens for each can get dusty; picture will gradually get dimmer and dull looking.

With set unplugged, remove rear cover (it can be done from front but back is safer for a do it yourself person..



With the rear cover removed look for the 3 large black lens pointing up in the middle of the set--simply clean them with a lens cloth or a paper towel with glass cleaner sprayed on it---this should usually be done once a year.

If they have not been cleaned recently or you are in a dusty environment, cleaning them should improve the picture a lot.


Let me know if you have questions.

Replace bulb sony KF-60XBR800


When you are in front of tv grasp the right side of the front grill and pull it off, the lamp door is right behind it. Unscrew the cover and remove it, you will need the allen wrench provided with the new lamp to remove the old lamp just unscrew it and pull it out.

Green flashing light - no picture


If the green power light is blinking and you have no picture, then your light bulb has burned out and needs to be replaced. It is not a cheap bulb to replace. If the TV is less than 1 year old it should be covered by the warranty
