Sounds like you might need a new projector or something inside is slowly going out on you. Get as much use out of it and only fix it if it's either really cheap or a free fix from a smart friend.

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.

Blothes of color in center and right side of screen. Very noticable when it's a light background.


May have burned CRT(s), (if you are not talking about convergence.) Burned CRT shows when that CRT (R,G,orB), does not show in an area of the screen where it should. Check bright white color = full R, G, and B CRT brightness. Gray = mid RGB brightness. Yellow = R+G(no B), Blue-green = B+G, no R, etc.

Gray margin & not right hue


I just purchased a Sony SLV-798hf VCR secondhand. It did not come with a remote or instructions. Thus I'm unable to set time or use the record function. I tried getting a manual online and was unsucessful.

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.
