Has the grainy picture not always been there? As this should happen on projectors with a very dark scene especially depending on the source. Has the bulb ever been replaced?
Thanks,
Lee

    1. Adjust color, tint, color temperature,brightness, or contrast in the menus.
    2. Pick another gamma setting
    3. Pick another color space
    Keep me posted,

There may be some problem with your picture tube else try this that looks like retrace lines. Anyway, you should try to adjust screen pot not focus pot. Make sure you are turning blue screen pot (there are 3 focus pots and 3 screen pots) and do it slowly. If you turn it too much, it will affect your grayscale

You can try cleaning the lens/mirrors of the set with a lint free cloth and a cleaning liquid made for cleaning glass. The dark image can sometimes be caused due to dust on these parts. If that does not work then I am afraid that you need to purchase replacement CRTs(the three tubes at the back of the set). Each of them produce one color - Red, Green and Blue and all 3 have to be replaced to resolve the problem, unless you can visually identify a malfunction with one of the tubes(If one of tubes is a lot dimmer than the other 2).

hi,

If you look directly into the three picture tubes you will probably see a haze in the blue one. This is fairly common but requires a knowledgeable service man to take care of.

TV picture is red.


Normal color picture is composed with 3 colors R-G-B (Red-Green-Blue). Picture turns Red means: Missing Green and Blue colors (many reasons: bad contacts, projector tubes dead, and other...). Try to give some "tabs" to diagnose ... I don't know what is the type of your Projection TV, how long you owned it, to have more idea.

Horizontal blue lines with a slight blue wash in the screen


Hi,
Its because of Over Voltage of Screen (G2) to Blue CRT.
Take off front lower cover (speaker grill) and unscrew board. There you will need to find Focus Block mounted having 6 control knobs. 3 knobs are for Focus control and 3 are for Screen volts control. Find Blue Screen control knob and turn is Counter Click Wise slightly until bluish shade disappear on screen including few blue horizontal lines.
If you select AV input to adjust that will be fine as you do not need to wait for dark-scene.

Dark scenes are impossible to see


This is a fundamental limit of Ti DLP. The part can not reproduce low grey scale, so low light film is dominated by artifacts. It helps to sit farther away from the screen. The color shift is caused by a factory tollerance on the color wheel, but there is no user adjustment for it.

Dlp has dark blue areas on screen


Have you tried magic focus? if that doesn't work
replace the pcb convergence board,, It costs $96 and takes 10 minutes to replace you will have to manually line up your convergence afterward as the settings go to factory default. Everyone that owns this set has or will have to replace this part within 3 years

Sony KP-53V85


My unit is 9 years old, almost 10 (in 2 months) and started the same a couple of months ago. The only way to fix it is to have them serviced by a tech and replace the projectors. Its just the age/use of the unit catching up with it.

Many resellers sold them with an offer to sell you an optional maintence service where they would fix/clean/replace the projectors for upto 5 years after purchase. I'm not sure if they even have the parts anymore since these tv's are no longer produced. After market repairs are likely to cost as much as or nearly as much as buying a new flat screen tv.
