P.S. I also own a Hitachi LCD CP-RS55 my screen looks normal for the first 2 mins then as it gets warmer the screen get a blue blob or streak.. Then in about 10 mins the streak takes up half the screen image. I was told by a t.v. repair guy the lcd panels need replacement. However, These projectors are WAY outdated (things built a year ago are already a thing of the past)and to fix it would cost as much as a new one or a good used one.

Panasonic DLP TV has huge yellow blotch covering most of the screen


SET uses a optical light engine--lamp which is quite hot shines into the engine---blue is first to get the light and heat and is usually first area in the lens and baffles to get damaged(loss of blue leaves red and green which equal a yellow screen.

You have a damaged light engine.

My tv screen when on turns yellow then after a while it will switch back to normal colors what can be wrong with it....


Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.

Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

The colour on my TV is a reddish colour. Have tried the colour adjustment. Skin colours in particular.


simple. easy. you have 3 screen adjustments. red green blue. turn color all the way down. you should then get just a black and white picture, but in your case, it will still be reddish. behind the speaker grill is an access panel for screen adjustment. remove speaker grill. remove access panel. you will see a block assembly roughly 6 inches square with 6 knobs on it. 3 are for screen, 3 are for focus. adjust until you have a black and white picture. then go into menu and turn your color back up. enjoy!

The picture is visible but there is an opaque blue area in the picture on the left side of the screen


Sony bravia

This blue is caused by magnetic fields. Either the speakers of tv is faulty or demagnatziser not working. Switch of tv and remove powercord from wallsockets. Leave for about 10 hours and plug in powercord and switch on. if demagnatiszr is working the blue will be gone. if not have youre tv demagnetized

If hometheatre or radio speakers are closer than ½ meter this could also generate coulouration of screen. move speakers further away. If tv is on and and being moved your static electricity can also cause this. So switch of if if you move your tv.

Blue Tint


Most likely cause would be a loose solder connection that expands as the set warms up until it no longer makes a connection. You may get the blue to come and go by hitting the side of the cabinet after the set is warmed up awhile. (don't hurt your hand doing this, and don't keep doing it to "fix" the set. The connection will have to be located and repaired). Otherwise, there could be a component going bad, including the blue picture tube.
