Sony Plasma 42B1 - No picture or menu on screen

Sony Plasma 42B1 - No picture or menu appears on screen - completely blank. The power switch does light though. I need to know which board may be the problem as I have another plasma of the same model that I could swap boards.

Hi,
As you said TV has no power and there is no sign of power in TV like its standby light.
Power switch or Power Supply board is bad and required replacement.
Check below image that shows power supply board location.

I have a 42" Sony Plasma Model# PFM-42B1 was watching tv when picture went out. Red standby light keeps flashing. Was told to unplug for 5 hours then plug back in & count how many times it blinks,...


Hi,

There are a number reasons why this might happen:
  • The backlight has gone (Find a dark place and shine a torch into the screen and see if you can see an image in the background, if you see an image then the backlight has gone) - Needs a new backlight (Engineer to remove and fit) or have a new panel fitted.
  • The panel has died - Need a new panel
  • A cable has worked itself loose or is broken
  • The inverter has gone - Need new inverter
  • The driver board is faulty
Thanks

Sony pfm 42b1 negative picture


Hi,

I have a Sony PFM-42v1 and it does the same thing, look in your tv menu for picture inversion, usually under screen saver. What it actually does is reduce the chance of screen burnin. By reversing the image it sort of resets the hot areas, brightest colours and the cooler areas being dark colours, switches them around ( negative ). This cools the hot spots and heats up the cold spots.

There should be a option to turn it off, mine and I guess yours as a default is ON, mine has the ON, timer and OFF options.

Hope this helps, please let me know if you need more info.
