My Mitsubitshi VS-50501A projection TV has a light sensor on front panel of TV and when the light in the room goes dark the sensor darkens the picture way to much so I have to keep the lights on to see the picture. Is there anyway of by passing the sensor so the picture is always bright? Thanks, Fred

Re: screen goes dark
I thught I answered this one but if you disconnet the sensor it should brighten up the picture If it dosent then its part of the brightness curcuit and must be replace. As I remeber thewre are severall models that you could simply disconnect. Or there should be an auto brightness feature in the main menu picture ajustment to simply disable or shut it off. Good luck

Find an active TV Repair shop. You may find a used screen in their salvage area. If they don't have one, they will know of another TV shop that may. Thanks for asking and show all hands of support!
when green light goes out on front of set press menu and input (device) buttons at same time and hold for at least 5 seconds and let go: if it has self check power light should blink a two digit error code and repeat it several times.
If no response it indicates some problem in main power supply (set is in shut down)
I need to know what skills you have; what I have seen mostly in these early sets is bad solder connections that develop on main boards; I can tell you where and what to look for but it involves getting at the boards and being able to solder.
Before you rate this information let me know what you find and remember I am here to help you.
You can order the remote for your model through www.tvrepairworld.com they can get any remote for any television. and the remotes dont require any programing since theyre designed to operate a specific model number TV.
most likly its your lamp you just need to get a new one off the internet or you can bring it to a repair shop and they will be able to replace it for alittle bit more then the lamp itself will cost
Good Day, jvira; Suspect fluid on the PCB's.To find suspected liquid on the PCB's, remove the front speaker cover and the small board held on by 5-6 screws. Look at the first 3 to 5" on the PCB. Use bright light it's not always easy to see. If fluid is spotted remove the boards from the back of TV. Use small brush, like old tooth brush, and acetone. You can get acetone from hardware stores Look for rusted wires or parts and replace as necessary. Good Luck, big IRISH.
Try hooking the TV to a different outlet fed by a different breaker. Does the problem go away? If so, the culprit may be a wiring problem in your house that is causing the TV not to get enough power unless the dining room light is on.If in doubt, consult an electrician to make sure both the dining room light and TV outlet circuits are working properly.
Check the vertcle yoke pins for solder cracks. Check verticle output circuitry resistors and transistors. And also check for Coolant leaks from the CRTs this happens alot. Check capacitors for any signs of sweeling or heat as well.
