We heard a "pop" noise


The pop noise could be a capacitor poping its top up.This is a common problem to most TV sets today. Usually located at the power supply board.Once this parts give up it usually shorts the circuit and blows a fuse.Replacements of these parts mentioned will often remedy the problem.Flashing power indicators indicate a problem.If you have the chance of counting how many the blinks are I could have told you the problems code are and the source of the problem.

I have a 52" Sony WEGA plasma TV. The picture went out, audio is fine. No TV picture, no dvd, no anything. What is wrong and how much do I need to budget to fix it? I love my Sony plasma!


that is because plasma tvs have a limit on there screen life and if all is done all day for months and months was watching tv ,playing games then you will need a new tv plasmas **** you can get same quality out of a lcd flat panel and three time the screen life or you could spend anthor grand and have the solution replace and maybe the that part of the control board went out and you will spending about half of what you paid for it to fix thats why i have two lcds have not had one problem with them one 32 for my computer and a 42 for me to watch tv ov on play games with and both the same brand and i paid 1200 for both brand new

50 inch Plasma problem


Most likely a capacitor in the power supply went out. otherwise it may be a bad relay if there happens to be one.
Most reason for a tv not turning on at all is bad power supply

My tv screen went green for a few seconds then went blank, the power light is on but no picture, my tv is not a plasma or lcd.


It appears that you may have either lost the High Voltage to your CRT(picture tube) or your CRT went belly up. There is also the possibility that you also lost the low voltage power supply feeding the Chroma circuits, but either way it will require a repair shop to look at it. You might consider getting a new TV.

The screen on my 1 year old 42 inch Akai plasma tv suddenly went blank although I still have sound. Any clues?


Reset the cable/sat box and tv by turning them off, unplugging them both from the wall outlet, and replugging them after 30 seconds. See if you get pictue back when they get the correct handshake. also, make sure that there are no loose cables going into the TV or into the cable/sat box. You can try using a different type of connecting cord from the cable/sat box to the tv to make sure it is not a bad connecting cord.

What type of cable is connecting your cable/sat box to the TV? Is it HDMI?

Are you using a video game system on the plasma?
