I got this set and the guy told me that it had bad caps. So i posted about replacement caps and their values.
There were no leaky caps at all in the set. The guy obviously lied or didn't know what he was talking about. Opened it up today but didn't have my camera. The caps are in great shape and the 1000uf are rated at 25VDC.
So here are the symptoms. Plug in set. Use remote to turn on. Led blinks continuously. i am able to shut off the set as well from the remote. I did measure 5 VDC standby and it was good. 5.3 VDC measured 5.2VDC and 13 VDC was at ~ 12.90 VDC.
Turn on signal went from 0VDC to .89VDC.
What else should I measure and any other things I should check?
budm wrote back and told me to do this:
"OK, this power supply-inverter board has built in pull-up resistors for the PS_ON and the BL_ON, so if you remove the cable between the power supply and the main board, when you plug the TV in the backlights should come on right away, if it does, it means the power supply is OK and the problem is some where else.
So far it looks like the main board is the problem because the PS_ON is only 0.89V (<1V = OFF)."
Well I think I did this already. The Main board is the one with all the input video connections and such?
If so, when disconnected and the set plugged in and then turned on, same thing, just the red led continuous flashing. But I will try it again just to double verify.
So I am starting a new thread here on this problem and added what budm has told me so far.
Hoping for help from all out there
Thanks
