    I have a Sanyo DP19648 HDTV, when I purchased it and hooked it up to cable it worked fine. It's been 4 months I've had TV and the other day I turned it on and now I get no picture or sound. Any reason why this is happening, any advise.......thanks.

    TV all of a sudden turned off and I can not turn it back on! Is this the kind of product sanyo offers? Maybe we all should look elsewhere for our next purchases. I was under the impression Sanyo created good reliable product. Whats up Sanyo?

My flat panel hdtv would not turn on, either by the power switch or the remote. The green power light would come on, but nothing else... no internal 'relay' click.. no picture, no sound. I puzzled over it for awhile, then fixed it in two minutes... how? I diconnected the power cord from the tv, let it set for two minutes and plugged it back in, turned on the tv and now it works wonderfully. try this and see if it works for you.

The tv is not coming on. At first the green light comes on then the light turns red.


Check the inputs on your TV, are they correctly inserted? Is there a device connected to them? Try to change the input on your tv.
If this problem persists, it is your power supply failing, and your tv needs maintenance.

Green light comes on no picmor sound


Hello Afox5, hi, make sure that there are no user controls or setup that are out of order. as a backgrounder, TV of this type mostly has two boards, power supply and main board. On the power supply board, this has two section, primary that deals with mains voltage and secondary that deals with TV supply current requirements, if you see green light mean that power on the secondary section of the power supply board of your TV is working, but it does not mean that the power supplied to the main board is correct, the supplied current produced by the power supply section to the main board that controls sound and picture needs to be checked, so voltages are needed to be checked and loose wiring, or screws needs tightening, are a common trouble, but some go to extremes like replacement of any boards.

The tv just suddenly stopped projecting video and sound. Now can't get tv to come on. When I unplug it from the wall and plug it back in the green light at the bottom is on and when I hit the power button...


1.You have a power supply issue on the main board of the TV.
Your TV will need service.
2.the inline protection fuse or the rectifier circuit has malfunctioned ( weak or bad) component and need replacement parts.
3. the clicking sound is the start up circuit but the voltage signal sent to the next circuit is not received therefore the system in not activated.
