Hi Pete,Thanks for the answer...
Hi Pete,Thanks for the answer to my previous question. It seems however I am now experiencing a power supply issue. It had been awhile since I was at that TV but was sure it was a main board issue. Nevertheless I replaced the main board but now do not get any picture or sound when turned on. I do get standby light momentarily when first powered on, then it blinks a couple times, then shuts off, then repeats. It does this two or three times (power cycle maybe) then completely shuts down and no standby light and none f the buttons on the TV respond. Only response I get is when I unplug then plug it back in. Thoughts?

Hi again, check for any loose wires or poor solder joints which may be causing an intermittent connection.

If you have a voltmeter available, check the outputs of the power supply board and let me know what they are reading.

OK. Please note as well after installing the main board I did not configure it as I do not have a remote.

You will need to obtain a remote to configure the main board.

You can get one from:

No loose wires and sauder joints look good. When I checked standby voltage (3V3 STBY) I got good voltage at 3.3 exactly but when I checked the pin beside it which was just (STBY) I got a lower voltage of 2.64. There are also 3 other pins with voltage ratings beside them on the board, they read +12.3V when I checked them all three pin voltages were 0.00. Where's the issue? I am a self taught TV technician as a hobby only, I have a basic working understanding of circuitry and electrical engineering but nothing more.
