Straightv from the SONY service manual

  • 2 times, Diagnosis: B overcurrent (OCP). Possible causes: H. OUT (Q8024) is shorted. (D board), +B PWM (Q8035, 8038) is shorted. (D board) Symptoms of the problem: Power does not come on, Load on power line is shorted.

  • This is not DIY stuff and is dangerous to play around with. I suggest you get a tech to fix it rather than opening it up and doing it yourself. Also dont keep turning it on in the hope it will start. It is more likely to start a fire if it begins to overheat from being constantly started and left plugged in.UNPLUG it

    Green power light blinks, and TV comes on, and goes out, and power light goes red


    Sounds like a problem with the power supply. After it shuts off do any other lights blink, apart from power LED turning red? Please provide this info as it is a self-diagnostic code that will help identify the problem.

    4 times blinking means Fan stopped, power is not supplied on Fan 1, Fan 2 Fan 3 and at Fan 4. Or Fan connector is not attached securely. Cleaning these fans by using a vacuum cleaner can also solve your problem. Sometimes these fans are clogged by dust.

    TV doesn't turn on


    If it does not give a picture at all not even for a moment, i would suspect a bad power supply, the circuit has quite a few components and either one of those could be giving you trouble.

    Sony kds-r50xbr1 turns itself off and then green light blinks 52


    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.
