Toshiba 50H81 very dark, blurry picture on all inputs.

check if the problem looks zig zag looking or it its not present in the PIP window. If so this may be an issue with the hypermodule - you can google TV repair Kits to find parts.

Picture is very dark and color not too good.

Take the front speaker grille off; it is stiff but will pull off. Take off the access panel underneath; four or five screws. Inside you will find a screen/focus block control assembly. Get a flashlight. Turn up the screen controls SLIGHTLY. for RED, GREEN AND BLUE. The best way to do this is to turn off the color first and make sure you end up with a good black and white pix ( not tinged green, red or blue) then turn the color back up in the menu.

HCL4715W Rear projection blurry

The focus controls on this set are in the front behind the bezel. I'm not sure, but, I think on this age of Samsung, the screws to the front bezel are on the back side of the set. After removing the screws from the back, the front bezel snaps off and the door behind the bezel need to be removed. Watch the wires connected to the bezel, they need to be attached in order to turn on the set. The focus controls are on a black control block (there are three of them, one for each color). Adjust each color for sharpest picture. I use words on the screen for alignment. Each CRT board has a screen control (Adjust each slowly until retrace lines appear on the screen and then back off until they disappear). You may turn off the color and make sure that the picture is black and white. If it is not, then, which ever color is dominant, back it off a bit with that screen control. Facing the set, Red is left, Green is middle and Blue is on the right. Use only one hand inside an operating television. Do not touch the board, just the controls. This concludes television alignment 101. Any questions respond to this post and I'll reply.

Sony KP 53S65 53" rear projection TV contrast issue

While the root of the problem is likely the picture tubes aging, I'm sure it would benefit from a cleaning and adjusting. After the dust is cleaned from the lenses, the screen controls could likely be lowered to get the blacks you desire. An experienced tech would be able to do this for you.

Sounds like a bad screen asy,part number 204809,must use the generic,or you could have weak tubes,if so you may just need to turn up the screen drives,this part is located in the right top of the set with the back removed,if no cracks are present adj. the three marked screen's,turn the color all the way down in your menu and adj. for a black and white picture.
