The substance that you are looking at is ethylene glycol, which is better known as anti-freeze, but it is optically clear. If it leaked on to a circuit board, this is not a good sign. I have not been able to repair a set that has been contaminated with this fluid. If your set still works you can replace the fluid and the set will be fine, do not run the set without this fluid as it will cause the CRT to overheat and may crack.

I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about type of fluid that you need. I think it is referred to as CRT coolant, and is sold by the bottle.
I hope that this helps
Thanks for using fixya

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 was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...


According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

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.

RCA HDTV HAS COLOR SPLIT ON SCREEN GREEN & RED


I HAD THE SAME ISSUE. I WAS LUCKY, MY TV WAS UNDER WARRANTY. THEY SENT IT TO BE FIXED. THEY REPLACED 2 CONNECTORS FROM THE PROJECTOR AND THE ON/OFF BUTTON. THE WIRES WERE NOT TRANSMITTING THE SIGNAL/ OR A SHORT IN IT. THEY REPLACE THEM ALSO. IT WOULD TAKE MY TV ABOUT 2 MINUTES TO TURN ON. THE COLORS WERE OFF. AND I HAD DOUBLE OR TRIPLE VISION. THEY ALSO REPLACE A FUSE IN THE PROJECTOR PART OF THE TV. THE FUSE ITS SELF COST ABOUT 275.00 WITH OUT LABOR. I DIDN'T PAY A THING I WAS ONE WEEK SHY OF MY WARRANTY TO BE OVER. EMAIL ME IF U THINK THIS HELPED. THANKS VERONICA.SANCHEZ@VETERANS.IDAHO.GOV

51 magnavox projection tv-color mixing wrong


The are controls on the inside of the tv above the circuit boards for focus and to turn up intensity of the projector lamps (red, green, and blu). If you turn it up too far all three projector lamps kick off. If this happens, power off the set and turn down the lamp that you turned up. Power it back on and slowly turn the projector lamp up until the picture looks OK. You have to take off the panel on back of set to get to the controls.
