Question about Toshiba 65HDX82 65" Rear Projection HDTV-Ready Television

2 Answers

Blue color issue

Sometimes during operation, sometimes when first powering on, the blue color seems to be out. I can detach the blue component video input feed, power off the set, reattach the blue component feed and power the set back on and then my colors are great. Sometimes it lasts for days, sometimes for a few hours. Any clues?

    I believe we are having the exact same problem with our Toshiba 43" Cinema Series TV. The blue colour channel is now separated from the others and so the TV generates a blue shadow or ghost image.

    We'll try disconnecting and reconnecting all the cables. But I suspect it's the TV because the problem occurs with both the satellite input and the DVD input.

Yes, the cable has been replaced. I've narrowed the problem to the tv, as in my original post, if I detach and reattach the cable I can make it start working again. Almost like something needs resetting or something.

Samsung HLR5067 has no green color in picture


I know this may seem dumb but if you are using component video (the red green blue with the white and red audio cables) it could very well be that the green cable (carries the green signal) is the problem. try changing the configuration (ex: use blue to carry the green signal and vice versa) if the green starts to work and the blue stops then its just your cable.

My color keeps going in and out , sometimes its red and sometimes its blue, what could be causing this problem


You are describing one of two types of problems:

1. Red and blue lines around objects and lettering.

2. Background of picture turns reddish or blue (a black and white image will tell you if this is the case.)

Both are fixable but number two should require less than 15 minutes and no parts.

Number one is different: Which best describes your issue?

OUR HITACHI 50V500A HAS COLOR PROBLEMS WE MOVED IT


This is an LCD rear screen projection TV. There is a Red, Green and Blue LCD pallet that is mounted on what they call an X-cube. If all you are getting is Red and green then something happened to the blue pallet. Either the Ribbon connector came off or is loose or something worse. How hard did you mover it?
Another thought. How is it hooked up. If component then this may be the issue as component video connections are Red, Green and Blue. Just a thought.
Let me know.
Blessings always,

Picture is red


If you are running component video, make sure the blue is plugged in and in the right spot. Component video works like this: the green is a black and white image, the red and blue are cover overlays to make the image display properly. So if everything looks plugged in right, then try plugging in a composite video (Yellow) or S-video cable switching to the appropriate input, and see if the image is still red. If so, go to the set up and set the set to factory defaults, and see if that fixes the color issue, It's possible that the color settings on the TV are messed up, with the S-video plugged in go through the set up menu and see if you can correct the color issue IF THE IMAGE IS STILL RED WITH THE S-VIDEO OR COMPOSITE VIDEO, otherwise the issue is a problem with the component video cable.

The color seems to be off. No red, and lots of purple. This is a Toshiba 57H81 wide screen big box tv. It was purchased in 2002.


Could be a bad board within the tv but it is sometimes the source input meaning it could be dvd player, cable/satellite box, etc causing the loss of color but it is unlikely. I have one of these tvs and they use red green and blue projectors to reproduce the colors so when the red projector fails then you get purple which is green and blue colors combined without the red. I have found it to be sometimes a bad connection inside the tv and I found insects such as roaches inside others. Using extreme caution when opening the rear cover of any tv due to dangerous and fatal high voltage. You might find that simply cleaning out the inside of tv and reseating all the connectors might resolve your issue otherwise you would have haul this tv to a repair shop where you pay half the price of a new flat screen lcd for just repairing this tv which will probaly have another color go out next month.

I have audio but no picture


Make sure your audio is connected properly as well as your video. I have found many people often mistake the white for yellow and vice versa.

White and red are audio. Yellow is for video.

However if you have a the Component Video Cables, which are Red, Green, Blue, Black and White. Make sure these are hooked up correctly people often mistake blue and black and sometimes green for the colors. Make sure when hooking up the cables you have plenty of light to avoid confusion.

43FDX15B has blue lines on the screen somtimes


Try this procedure:

Adjust the green & blue CRT screens to match the red. Go into your picture menu adjust, turn color all the way down to a black & white picture. Now adjust each CRT screen so that you end up with a true black & white picture. Then adjust each focus control to get a sharp picture, and adjust each CRT focus one at a time for clarity by covering the other two up. Then go back into picture adjust and turn color half way up, you should see a better picture.

If you cannot get the blue & green to even out to a black & white screen you have other problems such as faulty CRT card on back of tube or it could even be that the video IC is faulty. If this is the case, then you may have to get a competent local technician to check the TV and get the necessary parts replaced. It could set you back between $200-$400, depending upon how many components need replacing.

You can also try a hard reset..Unplug all cables, including power from the back of TV. Wait for 4 hrs and reconnect them. Try and see if it works now.

Hope that helps...Should you have any further questions, please feel free to post them here.

No color


You're using YPbPr (Red/Green/Blue Component) cables, right? Make sure you've got them in the right inputs and that the cables are FIRMLY attached. (Sometimes they seem attached even when there's a half-inch or so of space still)
