Question about Projection Televisions

I have a Toshiba 65H80 that has poor color. It looks almost as though it's a black and white picture highlighted in yellow. Blues show up, but no red and everything else has a yellow tint

    The picture is sharp and clear, blue objects are accurate but there is a yellow tint to everything else. If was a convergence problem, wouldn't there be blurry edges on graphics or other geometric shapes?

Try going to the menu and selecting the color bar and setting the yellow color lower than the rest (if you can). If you do not have just the option to change the yellow color, you still should have a regular color bar to change the different colors. After the color has been changed to fit your needs, there should be less yellow. It should be fixed then. Your menu option for the color may have reset itself.

Try removing and reinstalling the lamp to make sure that it is seated properly. Have you ever touched the optical assembly mounting screws? If so, its possible that its misaligned. If reinstalling the lamp doesn't fix the problem, then most likely the Optical block is damaged and needs to be replaced. If you have any questions about doing this let me know, but it looks like it may be a little project that you got if the lamp isn't the problem. If you need a place to order a new optical block from, let me know and I will post a place to get one from within 24 hours of your post.

I have a phillips rear projection tv model no 55PP8620/79. Its showing a a red haze and poor picture quality. How do I fix this?


If the red haze is not convergence---that requires parts.

The set has three picture tubes---with set unplugged and back cover removed clean the three large lens that are topside---as for the red haze a quick way to know what is wrong is with set on turn the color to zero----what color is the screen? Should be black and white--if red to some degree tracking or screen controls may need adjusting inside the set---Yellow picture in that situation is a different issue.

If you turn color off and stand back and examine the screen---if it is not black and white but yellow looking you have bad Glycol in the blue picture tube which is quite common.

Easy way to know for sure is with set on and rear cover removed peek with a small mirror at the three lens---don't touch anything with the set on===each tube red,blue, green should have a picture with the set on.

Likely you will find the blue one looks like a floodlight with little or NO image/picture.

Service man says light engine. how much? jvc model hd52g886


Whites are yellow can be a convergence or color balance problem, and lamp going out could also be a bad ballast board, black spots are usually light engine, could be a different fault on DMD board.

The fact is that when you get all this symptom together unavoidably you have a faulty light engine.

The light engine is the most expensive part to replace, its price for this model is always over $1600 ( I know, keep the heart tablets at hand).

Here is the part for your model: TS-COP7A-SAA-R

Toshiba 65H80 has yellow hue.


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

No. your problem is related to the coolant in the green CRT has congealed with bacteria and needs to be changed. Thats what causes the halos and general poor picture and color quality. The blue should be changed also. The red for some reason doesnt seem to be affected by the bacteria problem. This is a common problem that happens with all projection TVs phillips and magnavox TVs

Toshiba 65hx81 65" Rear Projection tv. black & white color/green


Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck

65h80


Yes look for www.bluestar-online.com and check your set and make sure it's the stk392-110. If you can solder you can carefully change it. I would replace all, you may have 2 or 3 in there. Also make sure you don't bridge the pins. Meaning soldering 2 pins together, just be careful. Unplug set and be careful of unscrewing board.
