When TV is turned on, green power light comes on and picture starts to come on, after a couple of seconds the picture goes out along with the green power light and the red standby light comes on and blinks three times, goes off, and back on again blinking three times over and over again. Model# KDL40W3000

I'm having the same problem right now. I get the green light for about 5 seconds (not Blinking) then the light goes out. No sound or picture.

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

The 5 blinks error code means that the lamp driver is faulty. How good are your electronics/soldering skills?

i am having the same problem. My Phillips 37" 37PF9431D/37I LCD High Definition TV won;t turn on. When I press the power button i hear a click and the green light comes on for a couple of seconds and then the red light appears. I can;t figure it out. Did you find a solution?

definitely, something wrong with it. TV shouldn't take more then a few seconds to start, I suggest, while it still under warranty, give Sharp a call to get it fixed.

change the lamp

I have a 40 but i was having the same problem. It turned out to be my lamp. I got a brand new lamp from Projector Lamp Services (relampit.com) and my tv works fine now. Im pretty sure that the 40 and the 60 take the same lamp. You might want to give them a call.

that is a common problem with this rca's check the convergence board for a short circuit
more likely is a transistor or an convergence ic

After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.
