Re: 6 red light blinks-possible thermal fuse prob.

The thermal fuse is located under the optical block. However the optical block needs to be removed to replace it. So unless you are very familiar with the disassembly of this tv I suggest you have a Sony ASC to do the repair work for you. You don't want to take a chance of damaging the optical block.

Sony KDF E60A10 60 in. My TV starts up but then the green light switches red and blinks 6 times. No picture or sound. What is the issue

6 blinks mean a thermal fuse problem. This model had a problem with the thermal fuse that does not close once it is opened. This is caused by a blockage of the fan that cools the optical block, usually from accumulated household dust. This causes the TV to overheat. The thermal fuse detects this and puts the TV into protect to prevent further damage to the TV. To fix, the fans need to be cleaned and the thermal fuse needs to be replaced. The parts are not very expensive (around 20 dollars for the fuse) but it does usually takes a while to fix because the unit needs to be taken apart to have access to the fuse and optical block fan. The GT board might have been damaged for the excessive heat but most likely a new thermal fuse will fix the issue and clean fans will prevent it from happening from the future.

Sony grand vega 55" will blink green for three times than red blinking under the power light. nothing comes on no sound, no picture and no fan's are running. Tried to change the bulb, power board...

Your problem is your thermal fuse.It is located around the bottom of the compartment that houses the lamp. You will have to remove the lamp and take the bottom back panel off. Then you will have to remove the fan. I ordered the thermal fuse so I would know what I was looking for when I started to replace it. If you take your time and are patient enough you can fix it yourself. I fixed mine and it's working great.GOOD LUCK!!!

Sony Wega KDFE55A20 screen and sound going out, red blinking lights, but comes back on...then repeats. Replaced the bulb about 8 months ago and seemed to solve the problem. But it is occuring way too often...

p# 19100239 6 blinks indicates fuse. Do not plug set into switched outlet. besure set is allowed to cool down before ac power is ever removed. Thermal fuse is on the optical block under the lamp housing. do goole search for part availability and source.

6 red light blinks-possible thermal fuse prob.

You need the location of the part that's stamped on the board near where it was soldered in. And you need a soldering tool to resolder the new part in and cut the excess wire with cutters so you're not to short out the circuit.

Screen goes black, 5 blinking red lights, screen back on for 20 seconds....cycle continues

Let me first say that if you are getting 5 blinks its not the thermal fuse. Your problem is your Lamp. You have what we call an intermittent Lamp. The only way to fix this is to replace the lamp. Part Number A-1085-337-A. Average cost $217.00

Blinking Green Light to Blinking Red

The lamp could still be the issue even though it looks ok. The other possibilities are the lamp ballast (power supply for the lamp) and/or the thermal fuse. In either case I would have a technician look at it so you don't replace parts you don't need.
