This TV shuts down a second after turn on and the power LED blinks 4 times. I would like a service manual if any one has it. Thank you.

hi gordon,
first let me ask you when you first power on set look closely and see if the panel ligts for just a moment. if it does then you probably have an open inverter transformer. I have had this model 6 times with the secondary windings opening. just ohm thm out....

Check the secondaries of the Inverter Transformers. Chances are, one of them is open.

Gordon,

Perhaps one of your backlights is flickering and the inverter board is
shutting it down.

There is a test to test if the problem is on the CCF tube or the inverter,is
difficult to do I did not try it myself yet,if you are interested I will
make a copy for this list,3 equipments are involved in the test, Scope dual
trace with 2 channels A and B , 50 ohms terminator and a true rms voltmeter.

Ok
I finally got a chance to return to that customer today and I tested the transformers. T1200 has an open winding. The next question I have is where can I source this transformer or do I have to replace the the board?
