Re: Samsung 32" TV. No image, backlight or Sound. Power LED Blinks 4 times.
Given this TV is 4 years old with the normal wear and tear, very likely the resistances of transformer can swing off the norminal values, similarly the CCFL or even the caps. This variance could likely be causing the OVP/over-current protection in inverter to kick-in shutting the driver to CCFL.
While waiting for the caps to arrive, i have re-soldered all leads on the inverter board. This seems to improve the intermittent issue, now the problem of blank screen is very much less often. But the underlying problem is still there. Hopefully caps or transformer are the issue here, I don't want to get to the lamps if i can avoid it. Tried changing lamps on LCD monitor before, dust and fingerprints are hardest to prevent.
