Question about Optoma HD72 Multimedia Projector

5 Answers

HD72 No Lamp function after replacement.

Lamp light LED shows red, manual indicates lamp failure.  Replaced lamp, that didn't work, then replaced light driver.  No change, lamp still doesn't work. On power-up, no red LED and projector appears to start up, fan runs for about 10 sec, (no lamp light) and then fan stops running.  The projector appears to re-cycle and fan starts again for about 10 sec.  This repeats for a total of three times in about one min, then red LED lamp indicator lights up.

    Connections were checked and double checked & verified actual contact with posts on bulb (wore rubber gloves). Original bulb had less than 800hrs & new unit was purchased from reliable source. Any methodology to bench test both bulbs for functionality or continuity? At $300 plus for a bulb a third bulb isn't a viable option. Also, is there any significance on the three attempts to start when the unit is powered up? Is that a built in duty cycle of the projector that would indicate the type of failure similar to an OBD-II in a car?

The projector is sensing the amp draw from the bulb and shutting down due to out of spec draw...replace the bulb.

This can be because the lamp replaced may be defective.

Also the connecting cables when replacing the lamp may be disturbed . You need to check the connection .

I have a Sony KDF-60XS955 tv. It won't power on,


I have that manual. There are three lights to the left of the power button. One is labled LAMP. The manual states "The projection lamp, which illuminates the picture, has a limited life. If the screen becomes dark, the color looks unusual, or the LAMP indicator on the front of the LCD projector TV flashes, it is time to replace the lamp with a new one (not supplied). Use a Sony XL-2200 replacement lamp (not supplied) for replacement. Use of any other lamp may damage the LCD projection TV." I also found in a different page " LAMP LED lights up in red when the lamp for the light source has burnt out." I guess burnt out would be extream. I found one other if you had opened the light bulb cover and didn't close it properly. " If the lamp cover is not reattached securely, the self-diagnostic function may be triggered and the POWER/STANDBY indicator flashes three times." You can down the sony manual at http://www.docs.sony.com/release/KDF60XS955.pdf

The lamp light is blinking once every 5 seconds. The manual says that " Lamp will not light or light is abnormal"


HI,

Panasonic PT50LC13 lamp indicator blinks to tell you the lamp is faulty.

You need to replace the bulb or TY-LA1000 lamp assembly. This link displays all Panasonic TV Lamps and TV Bulbs. This page shows Panasonic lamp location and How to Replace TYLA1000 bulb. TY-LA1000 Bulb Replacement requires the use of a long Philips Screwdriver to reach screws within the lamp cage.

Unplug AC power before removing the lamp and re-install all doors, etc, correctly before starting the TV. Vacuum any visible dust or lint from air vents and lamp area. Do not used forced air to blow out dust, big problems may result.

The user's manual has a description of what the Blinking LED indicators mean.

EPSON ELP5000 bought from surplus; plug it in and the power indicator glows orange and the lamp indicator is not lit. Opened the lamp unit and it is clearly blown. The user manual indicates that the lamp...


It is an indication that the projector is in sleep mode. Press power button and check for any changes on the led indicators. If the power turns red, it means unit is hot. check if the fan is working and if the air filter is clean or needs cleaning. If the lamp turns red it means the lamp is busted, You will experience this since lamp is clearly blown. But if both lights are red, it means that the unit is busted and will require service.

Lamp flashing, hd72 projector


In most projector menus there will be an option to reset the lamp timer, it's usually under the "settings" area of the menu. Try resetting the lamp timer and the light should stop flashing.

Once i powered the avision 220 on, The moniter shows E and 7


Hello,

When you first turn the scanner on, the READY light will blink, indicating that the diagnostics are in progress. Observe
the front panel Error LED (Red) closely. In a short time, the Error LED indicates the results of the offline diagnostics as
explained below.

Ready LED(Green) is off and Error LED(Red) indicates 7, the error indication is"Face down light check failure".

Followings are the solution for the above problem:

1. CCFL is on? Yes. CCD error, Optical assembly is to be replaced.
2. CCFL is on? No. Inverter error. Lamp inverter circuit is to be replaced.
3. CCFL is on? Yes. Issue resolved.
4. If the CCFL is still off, then CCFL is to be replaced.

Hope the above information is helpful.

Please revert if you have any doubt.

Thank you for contacting FixYa.

Regards,

TechSatya
