Question about Sony KP-53XBR200 53" Rear Projection Television
Red standby light blinks twice each time it blinks. will not turn on at all.is there a code for 2 blink red light i should know about.Is there a board I can replace to resolve this problem? BruceB.
2 times red light indication:
, 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 doesnot come on, Load on power line is shorted.
You will either need a repair technician or you can delve into the set yourself if you are a technician. You would be looking for bad caps, fuses, bad solder joints on the main power supply board.
it would come around 100$ ,even if we try to solve at a point the technicians does the work neat and clean for your valuable tv.
first try using a stabiliser,cuz if the current is not stable your board will short every time

2 blinks is +B OCP protection. The manual states "Short circuit of
power supply system in each circuit." and "Goes to the standby mode.
Short circuit of +B line"..
you have to replace the power supply board ...If you hire a tech, you can at least point him in the right direction. You would be looking at $150 and up since this TV would require an in-house visit.

Yes absolutely correct.you will have to replace the power supply board.its the power supply board problem.
to replace the power supply board is not a difficult job as it is just fitted by some screws and some plug in wires that is easy job.but the tough job is to open the tv to reach till power supply board.
the part number of power supply board is A-1316-400-A
you can get this board at
click the link directly and the cost of board is $198. but if you are not familiar with opening the tv then its quite advisable that you get it done by a local tv reparing technician.as it will be safe .
Please do rate the solution.Thank you for using fixya.keep updated. thanks

When power on the set, the green light blinks about 8-10 times before the light stays lit. Then the green bars appear. Looking at the service manual, it would seem to be an issue with the GI/GK board. Perhaps there is a connection problem betwwen the B1 and GI/GK boards. I did remove the B1 board and reattach. but the problem remains. Is this a direction I should follow (remove the GI/GK board and inspect?
My 2 cents,
