HL-R5667W Freezes & Turns off & on w/no controls

[Terence]

My Samsung HL-R5667W DLP TV is about 4 Years old and I recently replaced my lamp and the TV worked fine for 2 weeks. Today I was changing the channel and started getting intermittent picture freezing, with sound cutting out then the TV turns off for about 5-10 seconds then turns itself back on. Sound stays on for 2-3 seconds while picture stays on for about 5-10 seconds then freezes, TV cuts off and it repeats this cycle. Remote doesn’t work nor does the TV control buttons including the main power button. After several cycles of this the TV cuts off and the standby light comes on like normal. I then can cut the TV on by the remote or main power button but then the same cycle repeats itself again Could it be the DMD or Analog board and how much will it cost to fix? Can I do this myself or should I take it in for repair?

that kind of sounds like a digital board issue. did you replace the lamp with the same kind you had before? brand? you can enter the service mode and pick the kind of lamp you have. if the old lamp still worked before you replaced it you may want to try it to see if it works with the old lamp.

One quick thing to try... get a can of compressed gas used for cleaning the inside of computer cases, open up your set and blow out the dust. Installing a new bulb often disturbs old dust and if a bit gets in the wrong place it can be the cause of symptoms like you descirbe. Do it now to avoid damage to a board if that is the cause. No gurantees, but it helps more intermittent wierd problems than any other solution I've tried/recommended.

Hey Thanks Jason,

I unplugged the TV overnight and in the morning it worked as normal. Since then I only use the TV as a monitor, not using the internal tuner, since this all started while I was changing channels using the internal tuner. The TV is now connected to a Sat Box. I just use the TV's Input select and the Off/On buttons now and it's been working fine for 2 weeks! I'm still a little concerned that this was a omen that my Digital board is going bad! What do you think?

I'll keep my fingers crossed!

you can read about digital board issues on http://www.hometheatershack.com/forums/samsung/ the hlr5067w, hlr6167w and hlr4667w are also know for this issue. check out the big topic about the issues. some times you can find a cheap price on a digital board on DM do a search by the part number I see one listed now. it's listed as working on a sony. they have it listed wrong. this board was never used with a sony.
