I have a Sony Kp-51ws520 5 blinks

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

The standby/timer is flashing 6 times on my Sony KP-53HS30 TV

no the 6 blinks indicates a missing voltage. If your talking about a sony lcd KD or KE model you probably have a bad thermal fuse. You must also clean or change the Lamp fan so it won't blow again.

Sony rear projector TV problem, KP-61v35

This is a problem with the vertical circuit. This can be as simple as poor connections at the vertical IC or a defective IC. If you can solder, you should be able to fix this yourself. Let me know if you wish to attempt the repair and I will supply additional details and instructions.

KP-51WS520 wont turn on - standby & timer lights on constantlly

You need to check supply volts on main micro IC702 on main board of Sony KP-51WS520 TV.
If you have experience of big TV repair then I would recommend to get service manual of TV from any online store and check above said IC supply volts. TV must give error by blinking light in case any problem in drive circuits and if main micro fried, no error signal will be there.

6 blinks is usually associated with failure of the horizontal deflection amplifier - which shuts down the high voltage system as well.

The repair requires testing to determine the exact parts that have failed. There are, for example, a few hundred parts and a section of the Jungle IC chip involved. So, repairs could require something as simple as replacing some inexpensive passive components OR as complicated as replacing the jungle chip (very expensive).

most of the time it's the horz. transformer and transistor.
