Question about InFocus SP-LAMP-LP5 Projector Lamp for LP580 SPLAMPLP5 SP-LAMP-LP

1 Answer

Infocus lite pro 580

Image brightness fluctuates from normal, to bright. Thought over heating was the cause, as the filters were very dirty. I disassembled and thoroughly cleaned entire projector, and replaced both filters. No change, very irritating, Help me please!

I have noticed the screen is now not as bright as it use to be, still works just not bright. A darker look is the best way to describe it


Hi,

The most common indications of a weak bulb in a Sony LCD Rear Projection TV are:
  • Dimimage with low brightness and contrast.
  • NoPicture, Dark Screen.
  • Shadowsin Image, sometimes circular.
  • Intermittent Shutdown.
  • Fluctuating or Flashing Brightness.
  • Longerthan Normal starting time.
Also check for distortion caused by Optical Engine Failure. If any of these faults are present, bulb will not fix. Sony Optical Engine Fault Gallery

The tv has a haze look to it. Looks really washed out.


Thats usually caused by the front small mirror which gets dusty and the image will get very dull and washed out. Cleaning the small front mirror will restore the clarity and bright colors again. use just a damp cloth with water then dry thoroughly. If you dont know how to gain access to the small mirror up front you can get the service manual for that model emailed from the following link, It has the disassembly instructions.

Mitsu 65" DLP-picture seems washed out


Most likely cause of your trouble is dust on the small mirror inside you set. Your DLP set has 2 mirrors not including the DLP chip itself which has about 500,000 tiny mirrors. The 2 mirrors reflect the DLP chip image to the screen you view. The first is the main suspect it's about 4inches by 7inches. It's mounted on the bottom center facing backwards. This mirror faces slightly up and somtimes after time dust, smoke, dirt settles on it . The second fills the space of the entire back of the cabinet but it faces down and takes alot longer to get dirty.
The compartment is sealed but dust seems to find it's way in. If you remove the screws that secure the screen assembly from the top , sides and bottom. Make sure to have a friend available the screen assembly is delicate when it's not mounted to the cabinet. You can remove and clean the mirrors. These mirrors are glass and you can use glass cleaned. Don't use glass cleaner on the screen it's plastic. You can clean it if necessary with plastic cleaner only. Probably not needed.
Good luck.

Toshiba Sat A75-SP231, Display too bright no contrast


There is a brightness setting on your keyboard on ours it is Fn F6 to turn down the brightness. Just look for a sille "sun" symbol with a downward triangle symbalizing down. Try this and get back to me if it does not fix the problem we can try something else

could be one or more of three things.
1.could be the crt itself.(sony had a bad bunch of crts for this model)
2.could be the vertical ic on crt board.
3.could be the focus block
in my experience solutions 2 and 3 are more common....

TV shuts off with high color images . Example: explosions,bright lights etc


Normally, the screen control being up a little to high, would cause this problem. If no one has worked on this unit when it started may be a sign of something else, for example, the 200 volt line may be running a little low. Check the brightness and contrast for starters and if that doesn't help, then, the screen control would be my next step. Hope this helps.

JVC AV-27530 Sudden changes in brightness


This sudden changes in brightness are caused by the change in voltage inside the tv,not in the outlet in the wall but inside the set,The changes are an indication something is going wrong and it needs to be corrected,the set does have a brightness limiter but it only works when the set wants to get brighter than normal,You need the assitance of a servicer to correct this problem.
