3 times means Lamp and 6 means you have lost a voltage. You may have a thermal fuse blown. This set has a common trouble with overheating caused by the drum fan located on top of the lamp housing clogged up with dust. When the lamp is getting old it runs hotter and that combined with the fan being clogged the thermal fuse blows. You must replace the lamp and thermal fuse. You must also clean out or replace the lamp fan. This drum type fan should be cleaned out every year or two depending on the environment.
6 blink error is either a power supply (g2 board) or a blown thermal fuse. if it came back on, its not the thermal fuse so you would need a new g2 board. if it blinks 5 times, you need a new ballast (lamp driver)
You likely have an open thermal fuse. There is a whole procedure for replacing the thermal fuse and some adjustments that should be done when you replace it. If you feel like you are reasoonably technical and can handle the job, I'll try and walk you through it. If not, your best bet is to find a qualified Sony tech in your area. If you contact Sony at 800-222-SONY and they can recommend one in your area
The PROPER way to replace the thermal fuse is to remove the optical block first. There are at least two recessed screws holding the block in place. BE VERY CAREFUL removing the block as it is very easy to tear/rip wires when doing so. I cannot emphasize enough NOT TO JUST THROW THE NEW THERMAL FUSE INSIDE THE CABINET!!!! The thermal fuse is a safety device mounted near the lamp to prevent overheating. Those that choose to just let the fuse "sit out in the open air" are risking greater failures and the possibility of fire.
6 blinks is most likely thermal fuse failure. parts should be available through sony. thermal fuse is a 2 pin device under the lamp cartridge(looking from back) metal oblong looking peice that is screwed into the bottom of the tv. the new thermal fuse sent from sony will look completly different and as long as you cut the wires on the old one you can leave it in the tv and position the new fuse around the old one.
Is there a light flashing on the front? If you are getting a lamp light flashing you may need to order a lamp, that is a +/- $300 proposition. If you have a light flashing check for a repeating pattern, like codes on car flashing the check engine light. It may blink like 6 times successively then pause, then blink 6 more then repeat, this is a code 6, the codes will give some Idea of what is wrong (P.S. usually code 6 is a bad thermal fuse for the lamp on most Sony PROJO LCD's and would have to be changed out by a Technician).
