Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Picture I went to turn on my tv sunday night, and the picture colors are all mixed together with the red, blue, green. And the letters that say what channel and so fourth are running up hill. What would be the problem, someone told me the conversion chip might have went out. Would that be true?

Sounds like it. Replacement of both STKs is required. (They should always replaced as a set).

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.

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.

54" Projection TV

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.
