Hi


Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. X, Y sustain, buffer boards controls picture, fires the gas, and many others functions. When either of these boards goes bad common problems include negative image, no image, vertical or horizontal stripes on picture, turns on and than turns off, and many more. You’ll need to open the back off the TV and check for any swollen/bulged/leaky capacitors on these boards and replace whichever has gone bad. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

    If its a LCD TV then take
    a look at the power board-the board where, the power cords/plugs goes into. You
    might see some filter capacitors a little bulged up in the top-If this is the
    case-this is your defective part(you can try to replace them-but some soldering
    equipment is needed). If not, then probably the main board has gone bad. This
    is the other board-where all he inputs are going into. Also check for the
    Backlight Inverter Board if the sound is coming fine from the TV however as its
    shutting off so it should be either the power board or the main board. All this
    is only recommended if you have electrical expertise and know how to
    solder/re-solder components.
    . Please do accept the solution if
    the issue is resolved or else revert for further assistance.








    Thanks

I have a viore led42vf80 when turning on the light turn green but still no picture or sound can you please help me


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Hitachi 51UWX20B no sound, no picture, blinking green LED


The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.

No Picture & No sound. Red LED, Green LED, Red LED.


If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.
