Question about Mitsubishi VS-5043 50" Rear Projection Television
56 inch projection type 1990 mfg date vs-4504r
Your problem is one and or 2 differant problems. The power regulator could have went bad because of the convergence IC have shorted. Seen this a thousand(easy that!)Times. All parts in this set are soldered in and are not user serviceable. look in your owners manual or call 800-332-2119 to get an authorized servicer to come and look at your problem . I wish i could tell you what to replace but theres the Extreme Hi voltage inside these sets even when they are not plugged in .. Good Luck

They are not BULBS by any stretch of the imagination. They are CRTs (Cathode Ray Tubes, also known as "picture tubes," and each of them are small television screens, in essence), which are optically enlarged for projection onto the back of the front screen. Don't be tempted to think that you will merely be able to replace a "bulb" and have everything work!
Although you will be able to replace all of the components on the PC board if necessary (they all remain available), and may be able to fix the coolant leak that caused the failure, the CRT may have overheated. Considering the advanced age of the television, the tubes are likely already somewhat burned-in. Best to just dispose of the set.

A 22 code in Mitsubishi is a short circuit that is causing your set to go into protective shut down. Check the horizontal output and low voltage regulators for being shorted. Let me know if I can help you further, or if you need any additional info.

they are fairly similar to each other, did you get a error code from the led by pressing menu and input both in together and holding for 5 seconds?

Don't know that you can do it with universal remote. to release channel lock on previously locked channels or inputs, 1 press the menu button 2 press 5 3 press 2 (4) the display then askes for I.D> number (5) press 9 and quick view at the same time, this turns channel lock feature off.

If you have a Mitsubishi remote or the one that came with the TV, you can try the following.
Select the input.
When it asks for the code press and hold the QV button on the remote, then press the number 9.
That should unlock the input.
Then navigate through the menu and turn off the input lock, or any other locks that may have been set with the same key combo listed above.
I hope that this helps you with this issue.
Thanks for usning Fixya.
