Most likely the issue in on the large signal board. The TV is going in to shutdown. Repair might run $200.00 or so.

Open up the tv. On the boards that have connectors, de-attach all of them, one by one. Use a can of "duster" to clean out each receptical, then re-attach each piece. Do this to each and every connector on the boards inside. This should solve the problem.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS].

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Check whether Va & Vs voltage come to the display panel, from the main power supply regulator board. If not, the SMPS board [power supply regulator board] is faulty.

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years

My sony wega kf-50E200A tv keeps turning off. during each cycle the green light blinks 42 times and the tv comes on again for about 3 minutes and it happens all over again


More than likely the power supply is defective, but without testing and the repair manual that is just a guess, you make the decision to replace or repair the TV.

My tv has gone some orange colour


Try unplugging your tv and anything connected to it - you might want to take a picture first so you have a reference. I would also unplug everything connected to the tv: cable, stereo, etc. Wait a few minutes, then plug in and re-connect everything.

You can also go into your TV's setup menu and adjust the picture settings - try restoring the default settings first.
