Question about Samsung HLN467W 46" Rear Projection HDTV
This problem started 4 days ago when the displayed image scrambled the colors on all channels. My wife unplugged the unit until I returned. I powered it up and it came on for about 2 minutes, then scrambled. I unplugged as couldn't power off normally. Plugged back in after a minute or so. Picture came up ~30 secs later and stayed on for a minute then the TV shut itself off. 30 seconds later it seemed to try and turn itself back on but failed. This cycled for a few minutes so I unplugged as again couldn't power off normally or via the side power button. I plugged in and the preceeding repeated. I did this a few times and finally the TV came on and worked normally. Next day this basically repeated. I'm on Comcast cable and running DVI if that matters. I tried antenna input and same problem. Much appreciate any help. Thanks in advance!
Can we go further into light engine?. . .Is is shabby connectors, heat sinks, cold solder, caps, has anyone actually repaired the light engine? This is obviously a very common problem. . .I've replaced the lamp, balast, color wheel and bypassed the switch. . .mine still does this for 5-10 minutes, then will work fine forever as long as you leave it on. . .
