Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

SOURCE: Blue to Black screen on Sony KP-57WV600

Rowdyroddy,

Thanks you so much for this info.

I had the same problem with my Sony KW-57wv600. Blue screen turns black after a few seconds, and then standby light flashes seven times.

I called a local TV technician, and described problem. I was told it would not be cost effective to fix. After reviewing the "simple" instructions given on www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html I figured I had nothing to lose.

10 minutes to remove front panel, a "very slight" turn of a screw, and TV worked again perfectly. I could not believe it!

Thank you so much for your help!

SHAME ON SONY FOR NOT POSTING THIS FIX ON THEIR WEBSITE! SHAME ON THE TECHNICIAN AT SONY WHICH INSISTED A SERVICE TECHNICIAN WAS REQUIRED.

I have always been a fan of Sony, swearing by Sony products exclusively. After this experience, I am now forced to consider some other options when purchasing electronics in the future.

SOURCE: Projector screen turns off after 10-20 seconds

Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

for more info on this set please check out http://www.hometheatershack.com/forums/hitachi/38229-hitachi-p50h401-led-flashes-3-times.html
if will tell you how to trouble shoot this tv. these tv's are known for two caps in the power supply to go bad and they need replaced then you have to test the sdr boards if they are bad you need replacement boards or you can send them off to be repaired. the link for the repair guy is on the page. this guy also sells the repair on ebay but if you contact him directly i beleave the price is lower. just tell him you were send over by home theater shack.

If your handy you can repair this tv for not to much money. you need to buy two caps and maybe send one or both sdr boards out for repair. I would say anywere from 50 to 125 dollars you can repair it yourself. As long as no other parts are bad.

SOURCE: 42pfl7403d/27. Won't turn on normally.

Hello

The symptom you describe is consistent with an overload(short) on one of the power supply output voltages.

If you hear a clicking noise,that is one of the relays ,showing that the TV power supply try to start normally,but then a short condition is detected and power supply shuts off,and all repeats again.

Now from my experience with these units,the most common cause is the power board itself or the Y sustain board.To make the exact determination,further diagnose inside of tv set is necessary(voltages and resistances readings)-a common occurance would be some defective-bulged top capacitors in this power supply you will have to replace the board.

Depending on the models,these boards cost about-$250 to $300 each.Add another $150 for labor and the repair cost will be around-$400-$450.

I have a Hisense led tv model F39V77C.


Yeah, replace the set since it appears to be trashed. But if you have a few bucks lying around you might want to try replacing the unit's power supply to see if that resolves the many issues you have.

What color is the power light when the system shuts off?
    Red: If the power light is red, or flashing red, when the system turns off, then the system's battery needs to be charged.


    Blue: If the power light is blue when the system turns off, then there appears to be a problem with the system and it will need to be repaired.

    If the orange recharge indicator light blinks while the system is plugged in and charging, then it is likely that the battery is not installed properly.

    If you have ensured that the battery is installed properly but the orange light still blinks, check to make sure that the battery is a licensed by Nintendo. The only licensed Nintendo DSi battery will have the model number "TWL-003" (Nintendo DSi) or "UTL-003" (Nintendo DSi XL) and will display Nintendo's logo.

Please count light flashing again. Light flash time is "0.3 Sec" and there would be pause (light Off time) for "3 Sec". Start counting after pause to next pause.
