    This just recently occured with my Sony 55" LCD TV.  It's only 2 years old and can't see this TV be broken already.  Any idea what it might be? What's with this thermal fuse and where is it located?

    KDF-E55A20 sony tv

    I have this problem and have order thermal fuses from parts store




    I have opened up the back of the tv to reveal the electrical components. The cooling fan is to the right (when looking from the back) It is a 12 volt unit. Parts store list several fans 1-787-065-11 sony (sirocco--$76.15) or direct replacement 1-0787-460-11 $25.27 they also list another Sirocco fan with a different part number (same price.)

    My question is how do you determine if the fan is defective--

    I am leaning to the fan as a source of the problem. Not producing the right CFM (air flow) or pulling too much current or both.

    Also: in looking from the rear--where is the thermal fuse located.

I want to clean the projector sitting in the back as I see that there is some dust on it. I dont know if that is a good idea or not or if it will even make a difference with the image on the screen. I want to take a pc of cotton and windex to it while I am waiting for my thermal fuse. Anyone with advice?

The optical block would have to be removed or loose inorder to get to thermal fuse housing.Also make sure to clean cooling fans carefully to remove crusted dust.If fans are dust crusted ,then your thermal fuse may not last..

Sorry, I have to say it. If the bulb (LED) is shot it would have to be zero flashes :-) It's my weird sense of humour. After that I hope you'll forgive me and someone can give you some real help.
