Lamp/cover light blinking

I got this unit from a friend for our church.

It will not turn on, and the lamp/cover light is flashing.

I tried the covers as in the troubleshooting guide, but no luck.

Can you help?

    I have the same problem. The unit powers on, but the bulb never turns on, and soon the lamp/cover light is blinking orange.

    This one has a broken cover button, I have to use a pointy object to open the cover in the first place, but It doesnt seem like that should be the problem

I had the problem with the lamp/cover light blinking and nothing turning on.

I took the entire thing apart, messed around a bit, and put it back together disappointed that I couldn't find any apparent problem.

When I turned it back on it then worked. Must have been a loose connector.

Odd, but I am happy ;)

I think there is a common problem with the lens retractor mechanism as mentioned here
At first with mine I thought it was the lamp but when checking the number of hours it in fact wasn't. There's a little motor that opens the lens cover and one of the gears slips so the projector doesn't know it's fully open. Can just manually slide the lens cover then turn it on!

How do i determine if my ballast board or capacitor is bad in my toshiba hd tv model no 57HM167?

The chances of the ballast failing are small on this model. Count how many times the Yellow light flashes before it pauses. Then google 57HM167 and the amount of blinks. ie " 57HM167 Yellow light flashes 3 times" That will tell you what you need to know. You can also post it here and we can help. I suspect you have a stuck fan(the fans are monitored to see if they are spinning. If not, they will not allow the TV to start up). Or you have the cover for the lamp not installed all the way. There is a switch that the lamp cover activates and the the TV will not turn on without it secured.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

Flashing green standby led light at the front panel is an indication that the unit waiting for the lamp to turn on. Since the lamp led light flashes, the unit sensed it already burned out.
Faulty lamp driver has a different error code which is "flashing of the standby light 5 times".
Your unit will back to normal operation again after the lamp replacement.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hlp 5063w on off front button flashing lamp then stanby..hear sound no picture.. shuts off then comes on.

If the lamp and standby lights are both flashing and the timer light is off, check that the lamp cover on the back of the TV is properly positioned in the groove and secured by the screw. Take it off and check that the screws that hold the lamp itself are secure. There is an safety feature that keeps the lamp from turning on when the lamp cover is off.

If the three lights (timer, lamp, and standby) are blinking, then the lamp needs to be replaced. If the timer and standby lights are blinking and the lamp light is off, then a cooling fan isn't working. When only the standby light is blinking and the other lights are off, the unit is overheating and a ventilation area may be blocked.

I hope this helps.

Changed lamp and TV won't turn on, power light flashes 3 times

Red light blinking 3 times shows problem with lamp cover.
Lamp cover is not fixed securely in your tv after lamp replacement. Lamp cover is first thing that was removed to replace lamp, check lamp cover and make sure its back in place properly.

Tv went off while watching a program power standby red light blinks 6 times then pauses then repeats tried unplugging unit waiting a few minutes then replugged same results nothing. can anyone help me ?...

Here's an excerpt from the Sony Manual online. And the link -

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.

Wont start up


Pls clean the filters and check the lamp by opening the lamp cover. If lamp looks okay in all aspects then send the projector to any engineer to check the ballast unit of the lamp.
