    my toshiba 50hdx82 has an all green picture, but the menu items are in color. I readjusted all the colors convergence settings, but to no avail.

    Please let me know the fix.

    I have the same screen but the menu is in color...also the color is fine when there is an digital input. Also, the color is good when the POP function is being used where there are 2 separate pictures side by side on the same screen...but returns to green when you go back to single picture/full screen.

    Just this morning, switched on my Tosh 42" RP, about 6 years old, went and got coffee came back and the picture was green, just green. Sound ok. I tried all the inputs, same result. Menu comes up ok with all colours. Going to the convergence setting does show all colours and that convergence was ok. Seems like whatever handles the picture pre processing has gone? Help, I would rather not have to replace my TV yet.

The picture is clear but the colours are distorted like a sort of heat sensor is on the figures. Images of green and purple like shadows on the people in the picture

Are you using the component input. This is 3 wire video. If all 3 wires are not connected color will be off. This is very common. Cable may also be bad. How does the tv menu look? Press menu on tv or LG remote. Is picture bad on all inputs?You need to determine if problem is the source or the tv set by trying various video sources and inputs. If the tv is at fault but the tv menu is ok I would suspect the main board. If the the menu is also bad i would suspect the t conn board.

Mitsubishi wd 52525 lost greens and blues. only colors on screen are red hues.

This the classic symptom for component input wires being crossed. Check color coding on tv input and signal sourse. Green,Blue and Red wires must correspond. If ok Is the color off on the tv menu also. If so and wires are ok replace light engine.

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 a samsung2333hd and want to connect a dvd player using the connections marked pr(red) pb(blue) y (green) when i connect them all i get a redish pink screen then when i connect two of them i get...

OK no problem here. I can help. First reconnect the DVD Player to the tv using the Compoment cables. Match Green to Green,Red to Red and Blue to Blue.. If this is done correctly then you will have normal looking picture. If the picture looks like it is missing the RED color then switch both Red cables. The pix should look normal. Then connect the RED and White audio cables to the audio inputs . Now the Pinkish color is a result of the DVD Player not being set to the "Progressive" setting in the DVD Player Menu. It will help to connect a set of COMPOSITE cables from the DVD Player to the TV's Composite Input. Those are the Yellow,Red and White inputs on both the tv and the DVD Player. This will allow you to see the DVD player menu in case you cannot see the menu while in the Component input. The Pinkish picture should go to a Normal 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.

Fuzzy/ distorted tv pic

Projection sets have two very common problems.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
