My Samsung HL-85087W keeps shutting itself off periodically. I’ve been keeping the timer switch (in the back of the tv) down with a rubber band and that work for several years. I have also tried turning off HDMI signal but it still turns off after awhile. I’ve googled that it could also be the capacitor but I would not to repair that on my own. What else haven’t I tried?

Technician's Assistant: How old is your HL-85087W?

About 13 years old

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

It has not shut off on other sources

Technician's Assistant: How long has this been an issue with your HL-85087W? What happened right before this?

This just started yesterday. But I have notice for alittle while before this, the picture would clich alittle and I had to unplug the HDMI to get a clear picture.

Technician's Assistant: Anything else you want the TV Expert to know before I connect you?

I’ve also tried switching out HDMI cables

Sorry for the delay, just checking the service manual.

Ask Your Own TV Question

All 3 lights blinking at once indicate a problem with the lamp.

have you tried replacing the lamp?

Customer reply replied 5 months ago
But I can still get a picture and I replaced the lamp a little less the a year ago when the tv display didn't even come on.

The three blinking lights can also indicate a problem with the ballast board that supplies power to the lamp.

If it is defective, the three lights on the TV will blink.

That board will need to be tested and replaced if faulty.
