Turn on TV and picture and sound are great for about 60 seconds. Then the picture disappears but sound remains.


I would start with checking the power supply 12vdc output, make sure it is stable with no ripple. If the power supply checks out fine, I would then suspect the main board.

Lost picture


Try unplugging everything and then plugging it back in. When my xbox had the "ring of fire" my brother asked me to fix it and I just unplugged and re plugged it worked and came back to life. (be careful that you either have the instuction menu for setup of you can remember where all the plugs go, otherwise you'll have to right down what goes where or else you may get confused and never be able to fix your poor television)

My HyVision LCD TV Picture disappears after a few seconds


It seems that the "backlight" has gone bad. "Backlight" is the device that allows to see the picture in an LCD TV, when they are about to go bad the symptom that you describe is very usual. It depends on the tv manufacturers and model to expect how long the "backlight" is going to last in a tv.You can shop around for a replacement part and try to do it yourself or take it to an especialized technician. Good luck..

No picture 2 days ago power went out thru out the neighborhood, once power came back TV worked great. today, go to power on TV, here it clicking, but no picture... cable box working, cable working in 2nd...


It sounds like there`s a sort on the secondaries of the power supply. Before the power went off, did you ever turn the tv off by unplugging it?? In other words, did you turn the power off completely to the set or leaving it in standby?? if you always left it in stby, it will be the capacitors in the power supply, they dry out if the power is always on, so they will need replacing. If you did turn off the power, then I think you`ll find that the power cut had nothing to do with the fault you`ve got now, it will be the Line Output Stage which has failed or gone short circuit.

I would just replace the TV, the parts are not going to be made to repair this. The set is just to old.
