Question about Mitsubishi WS-48311 48" Rear Projection Television

1 Answer

Red projector problem?

The TV is about 5 years old. The weather got warm and the red turned off; when it cooled down at night the red came back on... for a few weeks. Now it is out all the time. I am pretty good with electronic equipment but never worked on a TV. From these symptoms, what do you think has failed and is it something that can be replaced easily?

Most likely its the red drive transistor on the Red CRT pcb which is defective, or it could be as simple as a solder joint issue on the Red CRT pcb.

    Usually when a red Crt goes bad it will turn the screen red with retrace lines or shut the set down. So chances are its in the Red Crt pcb instead

1 red blink every 2.5 seconds indicates a cover error-- for this check the lamp cover
2 times red blinks very 2 seconds indicates temperature error. for this let the projector cool off check filters and fans that there is no blockage of air for proper cool down
3 red blinks every every 2 seconds Power error. incorrect voltage input or internal malfunction.
4 red blinks every 2 seconds indicates Fan Error check the fans make sure they are working and not blocked or need replacing.

Best of Luck.

Red power, blinking red temp


Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

  • A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
  • A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.
Goodluck..

This happens to us at work quite often. Usually, it's just that the filters are dirty which doesn't allow the projector to cool and causing it to overheat. We just blow out the filters with a can of compressed air and it solves the problem.

Is the cooling fan working? (If not, then that's the problem).
Check that the intake grid for cooling is not blocked with dust and that it has adequate room to draw in air.

Panasonic PT-53TWD63, TV will not turn on, Red power light blinks


It is most deffinately a convergence chip issue. The die for no reason. They can be bought online for around $10 dollars and anyone with experience with soldering can replace them pretty easily. I have done it.

Replace Lamp Flashing


Clean the cooling fans, specifically the lamp cooling fan located inside the rear cover, above the optical blocker. This is easily blocked with dust and causes overheating of lamps/shortened life.
