My sony kds50a2000 failed lastnight. I turned the set on and the green power light blinked for a while. I then unplugged the power, waited a few minutes and powered it back on. Eventually the red lamp indicator light blinked. After removing the bulb I noticed a conductor attached to the filament is broken. The set has 6-8k hours on it. I ordered a replacement bulb but am wondering if there may be anyhting else that could cause the bulb to blow out this way. I definitly heard arching when the set is powered on. Obvously its because the bulbs circuit is not complete but could somethign else have caused the bulb to blow? Is it normal for a bulb well withing its life expectancy to blow ot this way?

You should Google the model number with "problems" as there are several sites with good information on this set.
I would suspect this model does not have a color wheel but if it does it would be suspect number one.
Sets that use a wheel that turns at 12,000 rpm will fail. I would (if I was working on the set ) take rear cover off and try to localize where the sound is coming from) Likely: the ballast that powers the lamp will buzz sometimes when bad or lamp is bad.
Remove lamp and inspect to see it is not shattered.
A fan (one on the lamp) could cause this but rarely.
Look, listen, and do some research with Google.
last resort Call Sony with model number (expect them to tell you take it to shop--usual response)
The blinking green light signals that the inverter board is charging the bulb. If the blinking goes to red it means that this process has failed because either the inverter board is not full operational or the bulb itself has failed.
Most likely you will have to replace the bulb - here it is http://www.partstore.com/Part/Sony/Sony/KDSR60XBR1/Royal+Philips+Electronics/Philips+Lighting/F93087600RL/New.aspx If this doesn't fix it then you will have to check the inverter and power boards and replace the failing one.

You tv used lamp XL-2400 or also known as F93087500. It is very common for this bulb to fail and have the exact symptom you are experiencing. I cant count how many times I have seen it.. Replace the lamp with either the exact Sony or an OEM and you will be back in business..
I tried this solution last night. had a similar issue. opened up the back panel and cleaned the fan. just for the fun of it, i tried to turn the tv on and presto. it works fine now and i probably saved a bundle. thanks!!!
4 blink is a fan error. This is caused by one of the three fans not spinning fast enough or has stopped completely. The fan that usually causes this error is the one over the bulb and toward the back of the set. The repair is not expensive, but to do the service correctly you must get all the dust out of the tv or the fan will clog up very fast again. Getting the dust out is kida tricky because you have to get the dust out without contaminating the light engine, if it gets contaminated you will get colored splotches on your picture. I recommend getting a pro to fix it, the repair should be fairly reasonable around $150 to do the repair. The fans are not that expensive.
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.
