My TV turns off by itself with siren sound after about 2 to 3 min. About a year ago, 3 lights blinking and turning the unit on problem occured. I tested by replacing the lamp with brand new one, but still same problem exist. Can you help?

the circut that detects the bulb has been also failing in these sets
and the conversion chip that controls the picture , and the transformers are not putting out the full power they are supposed to.
this set will need to be tested to determine the exact cause or causes
My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?
Its possible that one of your fans has failed, and or it could be the lamp itself. Sony television will not power on if a fan is faulty. Open the back of unit and look at all fans to make sure they are running, if so then replace your lamp.
I have the same issue, we've had to change our bulb three times in less than two years. now we have 61" expensive paper weight. Our current bulb is less than 6 months old. The TV is only 2 years old and like i said this is our third bulb.
the blue light blinks 4 times. you get sound. then a few minutes the the picture returns... then it goes out, and the cycle goes on.
I too have a Sony KDS-R60XBR1 tv and the issue that you are experiencing is due to one of your fans in the rear of the tv is not working. The tv automatically shuts off in protective mode. Make sure the POWER/STANDBY light is blinking and not the lamp light below it. Is the power/standby blinking 4 times in red? If, yes then its a fan that needs to be replaced. If its the lamp light blinking then you need to replace the lamp. The lamp is easy to replace by ordering the lamp either from Sony for $250 or find it cheaper for approx. $150 from other DLP sources and replace youself by following your manual. I hope this helps you.
It seems this is a self diagnostic function. the official sony codes are as follows
Five blinks - AKB circuit (automatic kine bias),
the timer/standby indicator blinks for about 30 seconds then goes to
the self-diagnosis function. Something is wrong with the video. Check
video out, Q705, 732, 761 and other components on the C board, also
check Q218, 219, 220 on the A board. In addition, unit could be in IK
blanking, try turning up screen slightly.
- No Horizontal (H STOP), no raster, goes to the blinking
self-diagnosis function immediately. Check C515 & 516 and the
jungle IC, IC206.
It sounds like you have a video input problem. Have you unhooked all inputs from the TV and tried to power it back on by itself? Hope this helps
I would suggest that you guys turn the unit off when this happens, unplug the unit for 30 seconds, plug it back in, and see if this helps. If this does not solve your problem, you should call 1-800-448-2244, so a service center in your local area can be found for further assistance.
