    Thanks the help. I did get a new lamp, but it still does the same thing, but I did not reset the lamp as you both suggested - I will try that and see if it helps. It may be one of the other things mentioned above.

Hi guys

If the lamp on any BenQ model is at it's life end there will be a on-screen prompt that will warn you about the hours.

I think in my 3 years of working on BenQ's , I've only had one problem like this that ended up in the lamp being the problem.

99.9% of the time it is either the Ballast ( lamp's powersupply ) or the lamp's blower fan.

Hope this is of help.

F.Y.I. The lamp can be reset by holding in the up arrow key for a couple of seconds until the on-screen display shows you step 2&3.

Replaced lamp on mitsubishi wd62527 worked for 10 minutes then shut down. Now red lamp light is on


If the red indicator light on the front of your HDTV is glowing a solid red, you should first unplug the AC cord from the wall power outlet and wait for 60 seconds before reapplying power to the HDTV.

After you turn the TV on, if it doesn't power up, try holding the power button down for at least 8 seconds. That's supposed to force a system reset. If your model has a system reset button, use that instead. Press the reset button for about 20 seconds...release it and press it again for 20 seconds, release it again and the led will blink just for a minute or two. You should now be able to turn the TV on.
If after several attempts, the HDTV has not fully powered on and the LED on the front of the HDTV is still glowing solid red, you may want to reseat the lamp.

If reseating the lamp has not resolved the issue then your next step is to order a replacement lamp.

Why does the projector keep going to standby mode?


If the lamp usage time has passed 2 000 hours (when LAMP POWER has been set to NORMAL), the projector will switch to standby mode after approximately 10 minutes of operation. The resetting procedure should thus be completed within 10 minutes.

1. Insert the power cord plug into the wall outlet and then

press the MAIN POWER switch.

2. Press the POWER button so that a picture is projected onto

the screen.

3. Press the MENU button to display the menu screen, and

then press the F or G button to select the OPTION menu.

4. Press the ENTER button, and then press the F or G button

to select LAMP RUNTIME.

5. Press and hold the ENTER button for approximately

3 seconds. The confirmation screen, "LAMP RUNTIME

RESET." is displayed and select OK.

6. Turn off the power.

This will reset the cumulative usage time for the lamp
unit to zero.

When I press power, light blinks for about 15-20 minutes, then goes off. Press power again, on solid for 30 seconds, then goes off. Press power again, TV finally comes on.


Your television is in need of repair. Hard to tell what exactly needs to be repaired but when the power light blinks in that way then this is the TV's way to tell you it needs to be serviced.

KDF-60XS955 Powers off and on every minute


The lamp light will not come on especially if it lights up during bootup from a cold start. The lamp only lights up on Sony when the lamp shatters in its housing and the system can't ignite the lamp from a cold startup, Sometimes it does'nt light up then. So if it lights when u first cut it on the sysem thinks its ok... But lets verify if the lamp is the problem.

With the tv off using your original remote, Press Display button-----channel 5 button----and Volume up button then Power button within 5 secs of pushing the first button, Screen should come on with a diagnostic screen, Look at the lamp driver option and see if its recorded any numbers to the right of it, if so then this is telling you that the lamp has stopped or tried to ignite that number of times..

Push the number 8 key then enter to reset the numbers back to zero.Turn off power now turn on the television and wait until it happens again, at this point go back to diagnostic as explained eariler and see what it has recorded. If it has recorded a 1 on the lamp driver then replace your lamp. Reminder: Once you have replaced the lamp go to diagnostic screen again and reset the numbers back to zero.

Hope this helps...Thank you

Here is the proceedure to replace the lamp and reset the lamp hours.
Lamp Replacement Procedure:
1. Press the POWER button to turn off the power.
2. Wait for about 1 minute until the cooling fan stops.
Note:
The lamp cooling fan will continue to operate for about 1
minute after the power is turned off. Do not unplug the AC
Cord from the outlet until the fan has stopped. Avoid
interrupting the power by using circuit breakers or switchable
power strips.
3. After the cooling fan has stopped, unplug the AC Cord from
the outlet.
Note:
Please wait more than one hour before replacing the lamp.
[ Forced cooling function ]
If you need to replace the lamp more urgently:
- The Projection display has a forced cooling feature.
After the POWER button is turned OFF, and during the
first minute of the normal cooling fan operation, press
the VOLUME UP button on the unit and CH UP key on
the remote at the same time for more than 5 seconds.
The cooling fan operates for about 10 minutes. (LAMP
LED will flash 5 times every 5 second and POWER LED
will flash red for 10 minutes.)
4. Remove the Front Cover Unit from the latches.
5. Turn the Knob to the left.
6. Pull the Lamp Cover out.
7. Loosen the Screw on the Lamp. Then, pull the Lamp.
Note:
Because the Lamp may still be hot, use caution when
handling.
8. Install the new Lamp, and tighten the Screw.
9. Install the Lamp Cover, and turn the Knob to the right.
10. Install the Front Cover Unit.
Lamp Time Reset Procedure:
Be sure to reset the Lamp time to "0" after replacing the new
Lamp.
1. Plug in the AC Cord, and turn on the power by pressing the
POWER button.
2. Press and hold the VOLUME DOWN button on the unit and
the SPLIT key on the remote together for over 5 seconds
in power on condition.
When the reset is finished, the display will indicate that the lamp hrs have been reset to 0 and the LAMP LED goes out.
