I need an email address to send you a copy of the service bulletin on how to do this the correct way. PLEASE do it the way describes in the bulletin, and not as other have described it on the site. If you choose to do it the east way, you risk having your very own timebomb/fire hazard sitting in your living room. I'll wait for the email address and send it to you. Thanks!

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.

The thermal fuse is located close to the front of the set just to the right of center, looking from the rear of the TV. Mounted near the lamp. Part# 191002393. Once you have the new part, it should not be difficult to find it in the set.

Thermal Fuse

The thermal fuse is usually located near the lamp to prevent the lamp overhaeting and damaging the set. Sony uses two types of thermal fuses: the first type is a circular metal type, about the size of a quarter with two metal tabs for push on lugs that connect to the TV. The second type is a small plastic half moon type woth wires coming from the base. Contrary to what you might read elsewhere on this site, it is VERY IMPORTANT that you mount the new fuse where the old one was, for safety reasons.

Thermal fuse replacment

The thermal fuse is located under the lamp housing in my TV. It’s a dime sized device mounted to the bottom of the TV with two wires coming out of it. The newer model Sony uses an upgraded thermal fuse, part number 191002393, that looks like a tiny black square plastic at the end of the two black wires. It is mounted next to the lamp (right side). It is accessible from the front. A skinny long nose plier can be used to grab the wires to lift up the fuse out of its holder but there is not much room to work with. Then you will need to remove the two screws that holds the plastic piece where the fuse is mounted. (the two screws are accessbile from the back using a long cross tip screwdriver). Then you have to slide the plastic piece back and lift it up a little to be able to slide out the bad thermal fuse and slide the new one in. I found this process very frustrating. If you do not have a lot of patience, I advise to just simply trace the thermal wires of the bad fuse back at the connector then unsnap to remove. install the new one in and just wrap it around the wires of the old fuse so it's not dangling. Install all the covers and enjoy watching (again). Hope this helps.

Sony model KDF55WF655 blinking light 6 red flashes,no picture,no sound....
I just replaced my thermal fuse for $4.80 plus shipping handling.Took me 30 minutes to fix and 30 minutes to get dust out of TV.Take off the back of the tv about 8 screws,then remove the fan housing on the right hand side about 4 screws.If you have the new fuse you will know which wire it is ..grey and white.I found it easy to get to the other end through the front panel of the tv only 2 screws ,remove front panel and then remove cover on projection bulb and you will see the other end of the fuse clipped on.Remember to unplug tv. TV is working excellent now .
Thanks to everyone on this website.I have pictures if anyone needs them to repair it.

If your set is going to cost you $495.00 to fix it then you might as well buy a new tv which will be cheaper.from my experience that tv will only cost about between $75.00 to $200.00 to fix.get an estimate from another tech have them take a look at it.before they repair.and let me tell you that it is not the whole power board needs to be replaced just the regulator and some other components.good luck.
