Obviously, check the fan to make sure it is running. Second, see if there is anything obstructing the fan, and then make sure all filters and fans are clean and free of dust build up.

I have the 50" SXRD XBR1 grand Wega; This has been a great set for 3+ yrs. A flashing red light promted me to replace my original buld (this site). I now still have a flashing red "power" light, shuts off...


Its the fan that cools the bulb. Try turning on the tv and look at the fan to the rear of the bulb. If the fan is not spinning that is your prblem. The tv has a safety switch that will cut off the tv if the bulb gets too hot. I was able to tap my fan with a pencil and get it spinning, but that is just a temperary fix. After a while, you will find the fan will stop working all together and it will need to be replaced.

Turns on and off then back on then off


Discovered bulb had blown out.
At power on button, red light and green light flashed and no picture was present. I opened side panel after unplugging tv and let the bulb housing cool, then removed the bulb and discovered it had blown. Luckily I had a replacement bulb from the purchase, replaced it and it worked again.

Power light flashed red 4 times then repeats no pic,new bulb/fan!


Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.

You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

TV won't turn on


problem is fan stoppage this is probable caused by excessive
dust in fan take off back and locate visually the cooling fans in unit
use canned air to remove dust until fan moves freely. if all fans
are clean maybe one fan is not giving rotation detect signal
look at voltage on white or yellow wire from fan s/b 5v then 0v
when fan rotates if one stays at 5v replace it
