How to replace the fuse on KV-32FS10?

I have had this for 8 years now and when I tried to turn it on, there was
a pup sound and now nothing comes on, not even the red light power

I am guessing a fuse was blown, but not sure. If it is the fuse, can it
be easily replaced, this thing is very heavy and if I can not access
it dont want to hurt my back.

Did you get your set fixed or did you replace it? My same set did the same thing. Turned it off for 2-3hrs after watching it and when I tried to power it up- nothing but the sound it would normally make just before the major power up, sort of a relay click sound. No picture or sound but the red light blinks non-stop.

Low voltage can create different trouble, sometimes a cpl at the same times. Call your insurance company and they might help you to build a direct request to the electrical distribution company (thats how it is here in canada) No simple tricks for that, experimented technician gave up in 33% on such situations. Not an easy trouble....

My 10 year old KV-27V22 turned off by itself and won't turn back on. No fault code(standby light) no nothing. Power to set is good.

Take the back off of the set and check the fuse if it is bad replace it be sure to uuplug your tv before you take the back off of it after you replace fuse if it is bad plug it up and see if it will come on if the fuse blows again then you have a deeper problem like the bridge shorted or transistor, restors in the power supply of the set.

Sony KV-36XBR400 power on/off unit unreliable

This unit has 3 power supplies. The secondary is the one that is used to turn on high-voltage power to the set. You will see a number of blinks on the LED, you will get sound, and then nothing.

This part is on the main chassis, it's called BOAR D, and t costs around $300. You have to do a little soldering to replace, so call i n a tech

Sony trinitron 32" just powered off by itself and won't turn back on.

Sounds like you all have a bad bulb that needs replaced.
This is a common problem.

TV won't turn on

Unless you know Solid State Electronics, there is nothing you can do. At best, You could unplug the TV, remove the back cover, slide out the Circuit board, and check the fuses. They will be at the front of the Circuit board, left hand side. But in all likelihood, it is not just the fuses, the Power Regulator STR would also be short circuited (happens often in SONY TVs) and so it is best that a professional technician have a look.
