Re: tv will not power up - makes a weird noise and red...
It sounds like a bad lamp, a bad lamp driver or a combination of the two. Be aware that sometimes a bad lamp driver will blow a perfectly good lamp, so if you're not sure which is causing the problem, replacing BOTH would probably be the best course of action

Hi, Question shows tv is Sony KDF-60WF655. Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen. Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure. Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem. Did you replaced its lamp in last 2-3 years? Thanks.
3 blinks is a lamp cover error, did you make sure that the lamp cover is screwed in tight? Also check the lamp cover for deformity, there is a problem with your model where the set over heats and melts the lamp cover a little causing it not to make connection with the lamp cover switch. Let me know if you find either of these problems? If not we can troubleshoot a little further.
Is the light blinking constantly or is there a long pause then more blinking. If constant check the lamp door switch . Usually it is broken or jammed. If you jumper it and the set comes on that it. 4 blinks is bad fan.
Please intimate exact model of your Sony TV and also mention how many times red light blinks as there would be pause of 3 seconds in blinks so count pause to pause and let me know to find out problem. How old is this TV and did you replaced its lamp? Thanks.
THE RED LIGHT THAT BLINKS IS IT THE LAMP BOX THAT THE RED LIGHT BLINKS IN OR THE STAND BY LIGHT THAT BLINKS ? IF ITS THE LAMP BOX THAT BLINKS THEN YOUR LAMP HAS BLOWN AND NEEDS REPLACED YOU CAN FIND THE PART # FOR YOUR T.V. FOR A NEW OR REFURBISHED LIGHT IN YOUR OPERATING MANUAL AND WITH THE PART # BUY A NEW ONE OFF EBAY,ALSO YOUR OWNERS MANUAL WILL GIVE YOU STEP BY STEP INSTRUCTIONS ON HOW TO REPLACE IT AS THIS IS A COMMON PROBLEM WITH PROJECTION T.V.'S IF ITS THE STAND BY LIGHT THAT BLINKS I NEED TO KNOW HOW MANY TIMES IT BLINKS AS THAT'S A SELF DIAGNOSTICS CODE THAT YOUR T.V. IS GIVING FOR THE PROBLEM AND FOR SONY THERESE NO CODE FOR 1 BLINK OF THE STAND BY LIGHT.
6 blink error is either a power supply (g2 board) or a blown thermal fuse. if it came back on, its not the thermal fuse so you would need a new g2 board. if it blinks 5 times, you need a new ballast (lamp driver)
