Try cleaning your air filter sounds like its a thermal problem, often its due to an obstruction in the air filter.

I have a 60' sony wega r60xbr1 i just had a new light engine installed last night the tv was never turned on afterwards . I turned it on the screen come on shut off imediatly the red led flashes 4 times...

LOOK IF YOURS IS A SONY I had a sony grand wega 60 inch with the same problem as many tv turns on shuts off the red led FLASHED 4 TIMES. it is a heating issue if one of the three fans inside are not turning when the tv is on even on the first few seconds of turning it on the tv will send a fault code of four flashes . Then the tv shuts off so it wont burn its self up or damage the optical block. all with this same problem of 4 flashes take a flashlite and make sure your fans are turning if not that is your 4 flash problem. I hope this helps someone and if it does i have done my job .

TV won't turn on. Flashes RED 4 times... shuts off

On this particular set 4 blinks can be either a fan error or a temperature error. Unplug the set and take the back off and see if the fans are running and also check to see if the lamp door might be warped. If the fans are running you probably need a thermal sensor.

Problem for Sony Grand WEGA KDF-55WF655. Hello,

5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?

Sony KDF-50WE655 will not power up. Red blight blinks 4 times

4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?

Sony Wega 55" Replaced Bulb TV still does not work

Hello, please check how many times the red light flashes. If it is 3 times this means that the lamp cover is not fastened securely. If the red light flashes 5 times this means that the lamp driver is defect. If you need more help please advice
