Hi, Aquired this TV about a week ago. Was dead dead. No standby
supply. I found an open winding on the primary side of the standby
xformer. Thought AHA !! Ordered a new one, put it in. Now, the
power LED blinks 5 times, pauses, and repeats. Theres about 4
relays n this things pwr supplies. None of em ever click. Any ideas?
TIA

Probably need to acquire the service manual and do some real in-depth
diagnostics of the standby power supply circuits. Any potential that opened
the primary of the standby SMPS Transformer probably also induced other
damage in the supplies, even maybe the controller circuits. At least with
the power led blinking you have minimal standby, enough to run the MCU,
Eprom, and the diagnostic routines. I'll bet you have open or damaged
components in the chopper - control circuitry of the main supply.
