I have the answer for the fan issue on the KDSR50XBR1!!!!!
Ok, I think I have the answer for the BIG FAN failure. I recently did a similar fix on the spindle of an xbox 360 and it is identicle. Ok, this is an EXTREMELY EASY FIX...
Open the back of the tv, locate the large fan (on the lower left on the back of the set.) unscrew the screen and remove the fan.
Once the fan is removed, you will see the side with the model number and the other side is totally open.
On the open side, pull...
The fan will come off, into your hand, it is only held by magnets...
You will notice a spindle on the fan and the other side has the magnets and the hole where the spindle came from (this is the fan motor).
Clean both the spindle and the hole (motor) with a q-tip. The hole is smaller than the q-tip, but do the best you can to remove the old lubricant.
Get a bit of WD40 and lubricate the spindle and spray a touch in the hole.
Put them together, reconnect your fan, test it on startup and thank me...lol...
HOPE THIS HELPS!!!! IT WORKS, TRUST ME...
What do you think? Spread the word, lets save some folks from spending needlessly...

SOURCE: Power on
The power board has parts going out on it. A slow decline in performance usually points to a bad capacitor or power transistor. Take a look at the power board. The board will show extreme overheating evidence if you had a meltdown. If it looks clean, maybe it is just a bad capacitor. If you see a capacitor that looks like the top is bulging out, that is a sign of a bad part. Unless you like to solder, consider this tv done for.
