    I as well have a flashing white screen, almost as if the subjects are getting thier picture taken. The lamp light on the front was flashing so we changed the lamp and it helped for a week. It seems to only be happening when it gets hot. We opened it up and cleaned out the dust and it worked perfectly again for about a week. Not sure what to do, and dont want to put anymore money into this thing. It is a samsung DLP HLN5065wx. Please help...

    Similar issue about the white flashing, with my Samsung DLP TV model HLN-467W. It starts after about 20 minutes, but if I place some external computer fans in the opening right above the exhaust fan vent, blowing in, I can alleviate the problem for a long period of time. What I've noticed is that the exhaust coming out is a lot cooler when I do this.

    I talked to a technician who thinks it might be the color wheel, but we were leaning toward replacing the capacitors on one of the boards. Using the fans, effectively cooling the bulb better, kind of makes me lean toward the color wheel now.

    Does anyone have any new info on this issue to help me out? I really want to keep this baby going for a few more years while the 3D TVs come down in price.

I sold electronics for sears for years and let me just say that samsung has a great picture and good price but they have a wide spread reputation for having bad mother boards and they know it if you buy one always get a extended waranty you will need it.

How can I get the TV screen to come on when only the power and OPC lights flash?


Even when the TV is off, some electronic components in your TV consumes power 24 hours a day. Maybe a power surge damaged your TV when the power came back on.

According to Sharp it is a software problem. Engineer came, installed software update ,10 minute job.....TV worked fine for 1/2 day unfortunately: Then images turned black and white in all channels TV turned itself off, and stanby and OPC buttons started flashing. When TV came back on its own 10 mins later , screen had 2 large square staines superimposed in image (as if it was a burnt screen)...Engineer will be back next week...all quite sad really for a new TV.....will keep u posted
