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?

    What are the chances that this is a red lamp?

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

TV turns itself off, then on automaticlly


The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

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.

Just got a broken TV


Man you may have a big mess on your hands the cooling fluid has probably gotten on a circuit board(s) and ruined it them and using the set with a cooling fluid leak is dangerous. You may need to replace the small signal board large signal board and the cooling fluid in the crt. I suggest this job to a pro

Red ghosting on images that are not closeup


1. Power off -- let bulb cool.
2. Display - 5 - VOL+ - Power (in quick sequence) to display service menu.
3. Go into the user menu and set auto revision back to auto.
4. Put an image on the screen that shows the problem. I always found the edges of a 4:3 aspect ratio signal displayed the ghosting very well on my set.
5. Use 2 to scroll through the categories to find D GM TG
6. Use 1 to scroll through items in D GM TG to find V POS D
7. Write down current value.
9. Use 3 and 6 to change the value to minimize the ghosting. You should only need to move it up or down a value or two.
10. Press Mute - Enter to save the changes.
11. Power off and let the bulb cool.

Won't turn on.. Operation indicator is red, Lamp indicator is flashing red??


According to the E44W48LCD service manual, the temperature indicator red light states the projection TV shut down due to overheating. Red (flashing) states the projection TV shut down, check the cooling fan.

Color off


You need to have the pins of your convergence IC's checked for ring cracking. That cooling-off period is probably just enough to bring the crack(s) back into contact with each other and as they heat up they separate. It doesn't sound like a IC or component failure, at least not yet. But if it's ring cracked that arcing that happens is placing stress on the Ic's and they could eventually fail... Good Luck Bill
