My panasonic th-42pwd8uk tv wont power on. When I press power it clicks to turn on then clicks again and the screen never shows up. No red lights no blinking lights just a solid green light.

Check the capacitors and replace the power components. It is an easy fix if handy with soldering electronics. Tv Repairman may charge less than $100.00 bucks to fix it !
Good luck

Sony pfm 42b1 negative picture


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.

Sony Tv PFM-42 V1 doesn't show any picture or tv menu

This is a common problem with plasma tvs You did not mention whether you could generate any sound like through your dvd player or something like that. Whether you have audio or not makes a difference on which board may be causing you the problem. Just because it does not have a picture for tv viewing does not mean it won't produce some type of sound through your av1 input. Try it and I'll try to be more specific.

Sony Plasma TV

I had this same exact issue yesterday. I own the same TV model and here is what SONY had me do to get the picture back. Ultimately the picture comes back, but it will be very dim and needs repair. Most likely a power supply issue. Try these steps:

-Press power off or leave with standby light on for 5 minutes (wait the full 5 minutes)
-Unplug TV / Press top buttons 5 times each to remove static from system boards (yes, each button 5 times each)
-Wait one full minute and plug TV in and press power on

Sony PFM-42V1 42 in

sounds like X buffer/scan or control/logic problems. without good service info you will have a hard time troubleshooting. And it will get expensive guessing. Could even be a panel, probably gonna need a pro look.
