Why does my Vizio 50" plasma tv not capture the video signal? It keeps poping in and out till it warms up and then it will finally hold the signal.


Be sure that your signal is strong enough coming through the HDMI or coax. If your signal is strong enough, it may actually be your TV's power supply needing to warm up.

LG 50 inch plasma wont power on?


U can chk the fuses in the back but it is poss u have shorted it out and it will need to go in to a TV service company. Mine was about us $ 150 to fix. I touched the satelite wire against the back grill of the tv briefly but this was enough. Dont forget to chk that u r getting power off the power switch it is plugged into. Also if it is plugged into something else chk that this is providing power out as it has fuses too. cheers.

Sanyo tv plasma model DP50741stopped working


Does it front panel light ON when you power up the set? If not, the problem is with its main power regulator board. If not, the fault must be to its circuit board.

Best plasma TV HDMI


None.All Plasma tvs designs are alway have high heat output and consume alot more A/C power energy than any other tvs designs out there.Tvs like CRT-tube tvs,DLP tvs -Projection tubes and projection lamps tvs,LCD-flourescent tubes tvs as Liquid crystal display screen tvs.All these tvs designs are all good tvs designs to buy but the pictures display and screen lighting and the sharpness of the pictures never have and able to compare high enough qualities as a display picture on the screen output to a Plasma screen tvs,until now LED-tvs are LCD and LED screen display combine to make it better and brighter technologies and now are good enough to compare to a Plasma screen panel tv.So buy a LED tv will get less heat output and comsume less A/C power energy too and it is good enough pictures qualities too.To compare too as a plasma screen panel tvs output.

We have a 50inch plasma and when we attempt to turn it on via the remote, the tv power indicator flashes and the tv doen not switch on


The most common cause of Failure in this unit is power supply failure caused by failed capacitors.
A visual inspection is The easiest way to identify and confirm bad capicitors on the power supply.
Such a capacitor will show one or more of these symptoms:
1) Bulging of the vent on the top of the capacitor. (The 'vent' is the impression stamped in the top of the can. The impression forms the seams of the vent. It is designed so that if the capacitor becomes pressurized it will split at the seams relieving the pressure rather than making it explode.)
2) Sitting crooked on the circuit board as the bottom rubber plug is pushed out.
3) Electrolyte (a crusty brown substance) leaked onto the board from the base of the capacitor
4) Venting from the top of the capacitor, visible as rust-like brown deposits, or a visible hole in the vent
Once the power supply is repaired or replaced your tv should work normally
