Sony KV-36XBR400 power on/off unit unreliable

Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits. To get more details, http://electronicshelponline.blogspot.com/

You are correct. You are right about the power supply and replacing with led hdtv. You will be happy with a Samsung led. Time to upgrade.

Hi.. Sorry to hear that the Picture is freezing.. Here are some of the steps that you can try:
*Try to connect a different video source with the TV like DVD Player, Blu-ray player and check.
*If the issue persists, disconnect the power cord and reconnect to a different wall outlet without the Power surge protector.
* If the issue persists, you need to contact the nearest service center to fix this.
Yes, you were correct many LCD TVs have problems compared to this TV.

this will require a technician.several components will cause this. usually the horiz.
output transistor and flyback transformer in the
high voltage circuit.

this will continue to degrade, almost any failure that can be affected or temporarily cleared up by hitting the set is caused by bad solder joints.

A good shop should be able to find and fix the bad solder connections for probably a little under $100
if you bring it to them and pick it up.

How many blinks are you getting?. Blinking codes tells a service tech what section of the unit is manfunctioning.

The full service manual for KV-24fs120 can be found HERE!

Problem is in the secondary power supply which provides power to high-voltage and scanning sections of main board. This is called BOARD D, and has the high-voltage section, flyback transformer, and control IC on it.

Can't be fixed by user, needs service tech and new part, around $300
