No picture; No sound

2 possibilities. First, the bulb which allows you to view your picture could be burned out. If that is the case, your tv will turn on and you will hear audio but no picture. $85 for a new warranted bulb from Shopjimmy.com. Second possibility. If your TV is on with no picture or sound, you probably have a light engine problem.$325. I don't think it's your light engine. Just don't have enough information. Check the first possibility first. The bulb takes less than 5 minutes to replace. Don't buy just the bulb, buy it with the housing. It doesn't cost more, it costs less and saves a ton of aggravation. Don't touch the bulb with your fingers, use latex gloves when working on electronics.

Sounds like a startup self test. All wireless devices go through a power on self test. Does it connect? You can connect to it and go online? I rarely turn mine off, only in a electrical storm.

sounds like the bulb needs to be changed

sounds like the projection bulb went bad. change the bulb and it should work. sometimes they make a high pitch noise when they are trying to turn on. the bulbs seem to last about 2 years for me.

ballast is not striking the lamp and needs replacing

When the lamp fails in this unit, often the thermal fuse opens. The error code is 6 blinks. To replace this part requires a great deal of deal of disassembly.

yes it sounds like it.

I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.

the tv will try to reboot a few times. just let i try and eventually it will start blinking red. if you could count the red blinks then i can further assist you.

Tried to turn it on? Sounds like you need to replace the lamp. However, I got an additional week out of my unit. Although poorly dimmed and the red Lamp light blinked constantly for that one week, at least it gave me enough warning to seek out a replacement. But so long as you're not mistaking the Power/Standby or Timer light for the Lamp light then I would have to agree with you. http://store.l-f-l.com/prod/A-1606-034-B Includes shipping to the United States and no sales tax outside of California.
