Screen will not come on. Power Light will turn green and sounds as if it is powering up. Worked fine a few hours before.

if using a box or receiver in line with the set unplug those as well. I assume the red light on the set is not coming on or a light is blinking?

replace the power supply board www.tvcircuitboards.com should be able to assist with replacement boards.

There is a small IC in the power supply section,
not the IC regulator that's the problem.

You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

I had the same sympton on my tv...it worked fine one day and the next day it would flash a green light a few times you would see the screen power on, but still be dark then the power light would go red. I couldn't do anything on the tv no menus or sound. It turned out to be a bad power supply, a new power supply will run around $200-300 - in my opinion it wasn't worth fixing. My neighbor was able to fix my tv - he repairs electronics - ended up cost me $100.00 - its been running for 7 months now no problems so far...I can have him fix this for you if you are in the area - shipping makes this to expensive..he is located in south jersey...or you can try a tv repair shop ( i called for this but they wanted between $75-100 to just look at the unit + repair cost - i would of been back to the 200-300 range) let me know if you need help...John

Have you tried unplugging the power for a few seconds and plugging it back in?

I had the same problem with an AOPEN 17' lcd that was left behind at a rental property... I plugged it into my dell dimmension 4400 in place of my old analog. It worked fine the fist night, and got up and when turned it on again it had the famed green blinking power light. I switched back to the analog, and just disappointed I plugged in the AOPEN to another power source, and power came on a steady red light. I plugged it back into the puta and it came on again. I have not turned the monitor off again for fear of the blinks, and has been working great for close to a week now. Hope it helps someone else out there. Richard

It sounds like the output transistors have shorted. This is VERY common. If you want to try to troubleshoot the problem, I'd need to see photos of the inside of the amp. You'll need a multimeter to check the transistors.

Before opening the amp, remove it from the power source.

Since the resolution is severely limited here, send the photos to me directly ([email protected]). If you're going to send multiple photos, please zip them and send one file.
