When the filter caps went bad, the power supply output will be AC and feeding the circuits which can damaged the parts on the board. Check to see if you have the 12 or 18v feeding the back light invereter board. There are surface mounted fuses on the inverter board also. Send me good pictures of the whole back where all the boards are and close up picture of the inverter board, may be I walk you through. budmrtn@aol.com

My samsung plasma tv powers on has sound and a picture, but is snowy, and coloring is slightly off. I have opened the tv to check for bulging caps and have found no obvious culprits. what next?


Snowy pics are not the symptom of bulging caps.
you must mention what type of source produces 'snowy' pics.
have you tried with other sources and ports ?

I recommend, you test out the following.
- DVD with Component connection
- HDR or STB with HDMI
- TV/Antenna

Screen Comes on and goes blank within 3 sec


Look for bad caps (bulging/leaking tops) in the power supply first, it may have taken out the fuse and transistors in the inverter circuits also.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor with a blank screen


The monitor is about 2 years old, time to inspect the caps in the power supply first, look for caps with bulging top. The problem can also be in the inverter circuits, or bad lamps. See example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

First, check to see if you do have 12vdc feeding the inverter bd. The problem can also be bad lamps (worst case). Capacitors look good? No bulging tops?

The problem can be bad backlight inverter board or it is not getting the 24vdc from the power supply. Look inside to see if it has bad caps with bulging tops. Also check the power supply output voltages, you should have 5vdc, 12vdc, and 24vdc.
