Had the same problem on my samsung LN-T4066. TV repair shop said it was fried. Couldn't be fixed.

Before I trashed it I took it to the Geed Squad at Best Buy. They sent it to there repair branch in Dallas. They fixed the problem for $84.00 ! Plus shipping. Said they had to replace four "caps"

Don't know what the caps are, but I was pretty happy with the Geed Squad.

I repaired a KP53SH30 with 6-blinks error.
Sony says the error indicated loss of or short on the 5V regulator. The 5V regulator was bad, so I looked at the 6-volt regulator (it supplies 6-volts to the 5-volt regulator input.
I found a bad capacitor on the "G" board. The top was bulged. It was in the 6-volt power supply. I replaced the 6-volt regulator, the two caps on the input, two caps on the output. I also replaced the comparator chip. I don't know what part was bad, but these parts did the trick. I bought all of the parts at Mouser for about $10.00.
If you are a techno, I can send you the service manual if you need it.
I just noticed your code is 4-blinks.
Sony says it indicates +/-15 volt not supplied, and IC8003 is faulty. Hope this helps,

    I meant to say the 5-volt regulator was good!

    Here's the stuff I ordered from Mouser.

    I ordered a variety of capacitors.

    526-NTE303 1g HEATSINK COMPOUND (for 6-volt regulator)

    647-UPS1V471MPD 35V 470uF 10X20

    140-HTRL16V1000-RC 16V 1000uF 105C

    661-EKME250ELL470ME1 25volts 47uF

    140-HTRL16V4700-RC 16V 4700uF 105C

    852-PQ1CG2032FZH 40V 3.5A, 70kH (6-volt regulator)

    526-NTE943M DIP-8 LOW PWR V-COMP

    Like I said, I don't know what part failed, but the parts were cheap.

    I'd look at the 5V regulator and surrounding caps as well (on main board).

    Good luck!

    I don't know how to upload the service manual. If someones knows how, I'll do it, or I'll be happy to share it via e-mail.

    I believe the Sony error codes are a Sony standard.

    You could try searching Agoraquest, though, I think you may have to pay to access their stuff.

    I've repaired 6 free projection Tv's this year. The Sony has the best picture of all that I have fixed(Hitachi, Toshiba, RCA, Samsung).

    All of the sets I have fixed so far had one or two bad capacitors. They look like they are bulged on the top. If you see one, it's probably a good place to start.

    Best of luck,

SOURCE: the power red light keeps flashing six times

The blink code means that something on the board is over current/over voltage. It could be an overload of the +5 line (A/B boards) or the +5 line is shorted.

The TV needs to be opened up and the boards checked. You may be lucky and only need a thermal fuse. Also check your bulb.

I hope this helps.

My sony won't turn on. when I use the remote to turn on it flashes green six times, I hear a click and then it flashes red six time.

six times means the thermal fuse on top of the lamp tripped. Replace it and give it a good cleaning and it should work.

Will not power on, red light flashing six times

the problem is in the power supply most likely. The overvoltage protect circuit is causing you not to be able to turn the tv on. This is common to all tv's. Solution unfortuantely is get another tv unless you know someone who can either work on or replace the internal power supply
