Replace 120k resistor on the blue video output module. Resistor is located next to the blue video output transistor (has heat sink). If you replace it with a 1/2 watt carbon type, it will probably never happen again. I recomend the same resistor on the red and green video boards at the same time.

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.

Intermitant color bursts of red, green, purple


Kevin,

for the color problem,most likely you do have problem with loose contact of components from C-board ( small board connected at the back of CRT "picture tube" which drives every color and size of the screen)if you have knowledge with soldering electronic component parts, resolder this board and also check main board for possible loose contact.

cheers,
mark

Color distortion


Move any speakers or electrical devices away from the set. It could also be anything electronic or magnetic. Anything near the set that generates a magnetic or electromagnetic field could be causing the distortion.

Green blur bot-R and up-L corner and no audio


If a standard TV has color splotches in 1 or 2 corners of the screen, it is possible that a large magnet, such as a large speaker, is or was near the set and has magnetized the picture tube. The set has a built-in degaussing coil but it is small and will only demagnetize small magnetic fields. Make sure there are no magnets near the set and if the colors are still off, have the picture tube demagnetized with a strong portable demagnetizer. As for the audio, when there are audio output jacks on the back of the set then there is usually an option to turn the speakers off. Some sets have a switch somewhere and some sets have a setting in the audio page of the on-screen menu. Look for a switch or go into the menu, navigate to the audio page and look for a speaker setting (ON / OFF) and make sure the speakers are set to ON.
