Repair will be costly, replacement probably cheaper

Do I need to clean the screen on a DLP television? I have only changed the bulb. I feel like the picture is getting less sharp.


Not the screen so much as the projection mirror which is located on the rear wall of the Set. If the mirror gets dull it can make the picture dim and dull looking. Cleaning the mirror will help. Some models have a small mirror which projects the image back onto the rear mirror. Dont use windex, just a damp cloth then dry good.

Help! Toshiba 51H84..Power light flashing, tv picture won't come on!


First thing that needs to be checked is the convergence IC's. Those IC's are located in the signal board and are really hard to remove. You need an experience technician to fix it for you :)

Picture has a green shade


Sounds like your red picture tube is not emitting enough brightness to balance the colors. A temporary solution could be to slightly increase the screen voltage of the red CRT to give a good black and white picture when the color control is turned all the way down. If the set has not been serviced in the last 5 years or so, and you're not ready for a new HDTV set, it may be worthwhile to get a technican to look at it and clean the dust off the lenses and mirror and evaluate whether a picture tube rejuvination might work along with the gray scale tracking adjustments.

The TV Picture


The most common reason I've found for picture deterioration with projection TVs is dust build-up on the mirror. Try popping off the trim around the screen and look of several screw and retaining clips and remove them. Now remove the screen - it's just a piece of plastic. Now the mirror should be in plain view. Simply clean it thoroughly with windex and newspaper (you can also clean the back of the projection screen since you have it out). Now replace the screen and see if the picture doesn't look much brighter and clearer. This should be done perhaps every six months as TV generate a lot of static which attracts dust like a magnet. If the picture is blurry after doing this, it's possible to adjust the projector beams (there are three) to better align with the position of the screen, however I'm willing to bet this won't be necessary after the cleaning procedure. It sounds complicated, but trust me, anyone can do this. If you cannot locate any retaining clips on the front, you may have to go in from the back, in which case you'll most likely have to complete remove the mirror to clean it. It's a little more involved than the frontal method, but equally effective. It's also possible that you have a bad projector. When you get the screen off, make sure that each one is lit (the red one always looks dimmer than the green/blue ones). If one is out, try tapping on it, it might just come back to life, you never know. If not, have it replaced (usually around a $200 fix). Hope this helps you, and good luck!

Screen spot


Since you have a black spot,you need to look at the mirror or inside screen. If it were a certain color, like purple or yellow, for instance, I would suggest a lens or picture tube, but, since it is black in one spot, I would suspect debris in those areas.
