Blinking Red Power Light

After watching fireworks in HD on the 4th, the screen went blank. Sound works fine. It has been in service for The front POWER LED is blinking 6 times red, pauses and then repeats. If I press the power button I get 4 green blinks and then the same 6 red blinks. I cannot turn off the set using the remote or the front onoff button. I tried a hard reset by unplugging the set and then plugging it back in, no joy. Manual says if power LED blinks 3 times it may be the cover to the projection bulb. I have removed the bulb and it looks fine. I reinstalled bulb, no joy. I checked the voltage that powers the bulb, sperry reads zilch. I also checked for continuity between the two leads on the bulb and it reads infinity, which makes me think the bulb is bad. When I press the power button I hear a click from within, but no fan action. A couple of questions: Is the service port on the back of the unit for technicians only? Is the first step replacing the bulb or do you think it may be something else? I am willing to perform further dissassembly of the unit and check voltages, continuity and peruse for fried electronic components. Thanks.

    Attempting to get anything on the screen ends in failure. I don't get anything on the screen with those button combinations to see which ones and how many times they have occured. What I think you are saying is it is time for a service call for repairs, yes? Or are there components I can buy and replace for this problem?

    Update to the blinking red power light. I saw another entry with the same symptoms (6 red blinks then a pause, no power) and decided to try replacing the thermal fuse, Sony part number 191002393 per the recommended fix. The original fuse sits directly under the bulb and ostensibly will keep the set from getting too hot by blowing and cutting power to the lamp circuit. The original thermal fuse is visible when you take the bulb out and can be accessed through the front, but you will need to take the rear cover of the unit off and remove the fan so you can have access from both the front and the back. Easy fix. The new thermal fuse is much smaller and simple to install. Set works great!

It sounds like the horizontal (H stop) and vertical (V stop) has gone bad. Check Cap 515 and 516. IC1509, Q1505 and the jungle IC, IC206. You can also bring up these fault codes on-screen to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, press the following buttons: Display, Channel, 5, volume Minus, ( not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problems named, are abbreviated as, "OCP", "OVP", "V STOP", ETC.

    If you know which components to replace, you can buy them yourself off the internet or a TV repair shop. That would save you some money. Parts really aren't that expensive for this type of TV. It's the labor charges that kill us. Most shops have a beginning rate of $100.

AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

The lamp can cause the picture to cycle without spitting out a lamp error. I'd replace the lamp and clean out the dust/dirt from fans, etc to hopefully resolve your issues.

I am working on one right now with a similiar problem. The power supply is bad in the one I am working on, and sadly, the part is not made anymore. I hope you have better luck than I am finding the bad component in yours. Sorry for the negitive answer.
