Rear projection 48 inch mitsubishi. Actually intermittantly goes blank, then back to picture, every few seconds. Not sure it's worth repairing, although it's been working well for a number of years.

A number of things will cause set to go "blank".

The most common problem is sets like this develop bad solder connections which is normal from age etc.

Provide me with exact model number so I can assist you more. You do have to be careful fixing a set over 10 years of age as some parts are no longer available.

These sets are very well protected, if a vertical problem where loss of picture, the set will blank all three picture tubes to prevent a line or spot being burnt into all three tubes.

The more you tell me the better I can assist you---model number and year set made will be on the back of the set.

Hi, if you describe the led light indication, a more accurate diagnotic solution can be provided. However, depending on the age and model number, it would most likely be the lamp or color wheel. You need to give model number, type of tv, number of blinks and any other indication like whining sound etc, Check out for more FAQs and solutions.

Mitsubishi ws-73903 73" red convergence is stuck and won't move.

I have to presume you have got the model number wrong--WS-73903 does not show as a good model number.

Correct model number will be on the back of the set along with month, year the set was made.

If you have a convergence problem with the valid model number I can tell you what parts need to be replaced and in many cases I have Start to finish, step by step instructions for this repair.

The instructions based on model number are free and if available for your model I can post them here for you.

If you are not able to do the repair most shops are going to charge 300 or more for this kind of repair--all the parts usually needed can be purchased on Ebay for under 30 dollars.

I cannot adjust the blue with the remote. Is there way to adjust.

WS-55805 ?

Look on the back of the set and confirm the correct model number--55805 does not show as a good model number.

If blue will not adjust what ever it uses (either one or two convergence chips need to BOTH be replaced and then the set adjusted.


Double check the model number and let me know and I will tell you what parts it uses and also then be able depending on the model number to give you the instructions etc.

My Mitsubishi tv will not turn on.

If you have the owner's manual, you will find that the blinking light is an indicator that the lamp or fan is the problem. I'm not sure of your model number. Can you confirm that model please? If you no longer have the manual, once you confirm the model number, I can look up the code for you. Given its age, I would suspect that the lamp needs to be replaced.

Please post the model number and I will confirm.
