Samsung SP43T5HP unit keeps power cycling


A couple of nights ago while my parents were watchign TV the unit decided to switch off and then seem to go into a "power cycling" loop. They could not stop it using the remote, the only way was to either unplug it from the wall or use the power button on the unit itself.

I had a look yesterday and when I pressed the power button on the unit again it didn't go into standby mode, it actually tried to switch itself on, the "standby/timer/power" (it's the one light) light flashed red 5 times then on the 6th time it went green, I heard sound for a second with no picture, then the unit would start the power cycle loop again.

I took out the batteries out of the remote (just in case that was soemhow causing it) but that didn't help either. At this moment I have unplugged the unit from the wall and will re-plug it in after 24 hours to see if that helps.

the manual for the unit doesn't have any troubleshooting steps for light sequences, etc so I can't do much. I am guessing it is the lamp but I would have thought the tv would behave differently to this.

Does anybody know what's going on?

    Same model and problem. I was told that when it went. The picture showed in green and black/grey so I guess if its a lamp it would be the red one. The sound was fine when this happened. Thats until it was turned off. now when you turn it on it has this problem. Does anyone know which bulb is the red one.

I had this problem in December...ultimately it was a problem with the digital board (the tech tried a new light engine first, but that didn't fix the issue). Pay attention to the lights on the front...but if the picture doesn't come up at all and the power just cycles, your issue may be bigger than just the lamp.

You must change the bulb. It is worn out.

TV doesnt turn on. It cycles thru a couple of times and then stops. 2 green lights and 1 red light flashing on front panel. replace lamp about a year ago

Check the filter and see if this is clogged. If so clean and reset. The processor of the projector seems to switch off power due a feedback error and must be traced.
If the lamp holder is loose fitting, if the lamp has failed or if there is problems in the power section this can trip.

Screen is filled with a circular Red/Green/Blue pattern

The problem will be with the de-gausing circuit, this de-magnetises the tube when the set is switched on from cold, this is a fault you will need to get an engineer to look at ie, not a D.I.Y repair.
