Tx32pl10 sound but no picture

SOURCE: The TV turns on and you can hear the sound but the picture is dark except for a thin line of blue dots in the center of the screen.

You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck

Its probably a bad cable otr the connections inside the set where the scket connects to the chassis has broken connections on the mounting. To fix this your gonna need to know how to solder and know the HI Voltage issues with tv sets so if you dont please seek a pro to assist you with this repair. Good Luck

SOURCE: Black screen

could be some bad solder connections on the crt socket or around the flyback area dealing with the brightness

SOURCE: The TV cuts off frequently. The screen is blank & no sound.

It is probable you have a poor soldered connection on the power supply board, hence the erratic timing of the TV going on & off. If you are competent with a soldering iron look for dry jointed soldering on the board. If not have a service engineer take a look at it for you.

I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.
