Re: how to fix?

Are you sure you have not mis-plugged your component leads, and what source are you seeing this from (PS2, DVD player, etc)? You are describing what would happen if you happened to accidentally connect the Y to the R channel, G to B, and B to R.

If you are getting this from an S-Video or Composite input instead, let me know and I can look at it in greater detail.

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.

My projection tv lost its blue tint


Thanks for using FixYa. Usually this happens when the Light Engine has gone bad, and I should say this is a common issue with Projection TVs. There are three tubes/mini LCDs inside your TV- green/yellow, blue and red. When the set heats up over time of usage the screens tend to break resulting in leaking color everywhere. The cost to get this fixed by a professional should be around $300 depending on the parts that needs to be replaced. Please do accept the solution if the issue is resolved or else revert for further assistance.

This is a common problem. Its called a convergence failure.

Toshiba 65H80 has yellow hue.

Check you HD inputs or source. Sounds like the red stream is missing; maybe a loose cable.
