Question about Mitsubishi SL1U Multimedia Projector

1 Answer

Overheating? I was wondering if the lamp is not good, would there still be a light and projection on the wall? Would this cause the picture not to come from the laptop, but still act as if there was a light? Also, the lamp warning light did not go on. Thanks

The Basics

Before we explore more complex tv troubleshooting techniques, we need to examine the basics. First, we need to verify the TV is securely plugged into a power outlet. Don't laugh, but failure to plug-in the TV is the number one reason reported why electronics do not work. Second, you need to verify the remote has fresh batteries. This can easily be overlooked. The remote can be working one minute and not working the next, so replace the batteries Finally, verify that all cables and connections are correctly and securely attached.

Lamp Problems

Rear-Projection TVs have a lamp, which picks up the picture and projects it on the TV screen. A burned-out or connected lamps are two of the most common problems for Rear-Projection TVs. First, you will want to confirm the bulb is still good. If the bulb is bad then then replace it immediately. Second consult your user manual and verify the lamp and lamp cover are installed properly. Most Rear-Projection TVs have warning light which notify you when there are lamp problems. Again consult the user's manual to see what each light means.

Overheating

Temperature is a common reason why many Rear-projection TVs do not perform well when they get to hot. You may start to see your TV shutting down automatically when it overheats. Here are a couple of things you can do to prevent overheating. First make certain any TV ventilation ports are free and clear of debris and dust. Second make sure the TV has enough room for airflow. Third, the temperature in the room should be around 72 degrees. Due to the high degree of heat generated by a rear-projection TVs, it is not advisable to watch TV on a hot days when you don't run the air condition. This could cause damage to your TV.

Configuration Problems

Improperly configuring TV setting can cause problems. Verify the TV settings are set correctly. First, brightness and contrast should not be set to high or to low because this can cause poor picture images. Second, adjust the color on the TV when the picture displays colors poorly. Third, if you are having sound issues then check to make sure the volume is not muted or turn down all the way.

Reset component settings. Usually, the problems you encounter with a projection TV may be resolved through the resetting to its factory settings. If you experience inaccuracies in the color, reset the television's PerfectTint/PerfectColor capabilities. Simply press the Menu tab and then highlight "Perfect Color" using your right key arrow. After this, press "Enter" and then "Reset" in order to reset to factory settings. If you have audio / video problems (VCR or DVD player), simply press "Menu" and highlight the "Reset" option.

Sony, KDFE50A10, Heard a pop and the picture went black. Now have a flashing red light.


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

I have a wd52628


This area of the TV is a cause of some expense in rear projection.
The fan controls the temperature of the lamp. An obstruction keeps the fan from coming up to speed.
The power block controls the power the lamp uses. This helps keep the glass of the lamp from breaking breaking.
An arc is a badly mounted lamp or a lamp defect.
Dust build up can cause overheating.
Most of this area cannot be serviced by a non-technician.

that is an overheating problem. With the TV unpluged clean and or vacuum the internal tubes. Not the lamp though. Do not touch the lamp as any oils on your hands will cause a hot spot and the expensive lamp will fail.

there are 3 leds on the front that blink the error code. which leds blink gives you the error. if its just the standby/temp red led blinking, it has overheated for some reason. there are a couple other fans you could clean but check your ventilation. many people put too close to the wall or close it up in a cabinet. it needs atleast 4" from the wall and someway to vent out hot air and get cool air in. a different model had the temp sensor cause this issue, it is the silver thing right atop the lamp. you will have to pull the whole back panel possibly, there are two wires that hook to it and two screws holding it to the engine (lamp housing). if you get lamp and temp leds blinking, reseat the lamp door. timer and temp leds is a fan error, all 3 leds is a lamp error (lamp, ballast, colorwheel, dmd)
