This is caused by a faulty convergence circuit. This would run around $300-$500 to have a repair man come and fix it.

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.

I have an older 2004 or so philips hdtv projection tv with the built in tv stand. i want to connect my HD cable box but there are no hdmi ports. and i buy a wire with the VGA on one end and hdmi on the...


Get a component video cable (blue, green, red) and a separate RCA audio cable (white and red) if your cable box has a component video output and the TV has a component video input.

If your cable box doesn't have the component output, you will need a converter to go from the HDMI to component video. Something like this: http://www.hdtvsupply.com/hdmi-to-component.html . There are other converters available if your TV has some other inputs available.

A cable that has an HDMI M on one end and a VGA M on the other will not work. HDMI signals from the set top box are a digital signal. The VGA port on the TV is set to read an RGB analog signal. (Similarly a component to VGA cable would not work since the RGB and PbPrY are not compatible.)

I hope this helps.

hi friend,

Computer monitors work the same way. Here's a few web sites that list proportional colors:

http://www.tayloredmktg.com/rgb/
http://www.web-source.net/216_color_char…

or just plug "rgb colors" into Goggle.

There's more than you may want to know about it here:
