Sony repairs certain power supply issues without charge even if the unit is out of warranty.  They fixed mine free.

I have a sony pfm 42b1 that now has the standby red light flashing continuously while on.... what to do??


It is possible that the TV was hit by a small power surge, and the audio processor is locked up. You need to unplug the TV from the wall for 40 MIN, and that will reset the audio processor back to normal.

My television powers up comes on for a second and then dies and the stanby light just flashes. i can hear the fans power up then it just dies straight away. How can i fix this? and what is the problem


Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over. You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Sony pfm-42b1 plasma tv goes to a flashing standby light when turned on - any ideas / info would be greatly appreciated - thanks


How many blinks do you get ???? It put itself in protect mode so the TV thinks something is wrong.

2 blinks X sus circuit board temp is too high

3 blinks y sus circuit board temp is too high

4 blinks center temp is too high

5 blinks digital 5V circuit is messed up

6 blinks means the PDP Panel board has failed

If you feel you cannot fix it or its too much money I will buy the TV off you for a part that I need for my sony pfm-42b Please email me at joekeniston@gmail.com and we can discuss this in more detail

Thanks

My sony Sony PFM-42B1 blink 5 times


When a Sony TV flashes five times, that means that there is an AKB circuit fault.
This means that there is something wrong with the video.
Try first unplugging power for few hours, if that does not work, call a technician, as several IC and components must be tested and eventually replaced.

Your best bet, if you have ther board out yourself is PTS Electronics. Techs even feed these guys because they're well known for their quality of work and reasonable price. If you're looking to have a shop there bring the whole set in and work on it maybe this will help.
