It sounds like you have an integrated power supply issue. This type of supply truns on the horizontal oscillator which provides excitation to the Horizontal Output stage which in turn work with the HV section of the TV the extra LV levels are supplied by this interaction. That tsss noise might be the oscillator trying to work or the startup circuit trying to work. I would check the Horizontal and HV sections for failed components.

Have vizio vp50 part#1014350022 went to turn it on and nothing no lite sound or anything.Tried the reset nothing any ideas. thank you


The first thing to check is if your power outlets have surge protector breakers. Try plugging in another simple appliance like a lamp into the outlet and make sure the outlet has power.
If the outlet is fine try plugging in the TV and listening very carefully from the back of the TV for a subtle click noise. The power supply has a mechanical relay that switches when the TV receives power. If you can not hear the click and there are no stand by or power lights illuminated then you likely have a power supply problem. This could range from a blown fuse to a bad capacitor up to a burnt out power regulator. Anything more serious than those problems may warrant simply replacing the whole power supply. Depending on your TV that board could cost anywhere from $50-$175. The power supply can be tested using a multimeter to determine if it is the source of the problem but this should not be attempted unless you have some electroics repair training and are aware of the dangers involved in working on high voltage electronics.

1990 panasonic tv model# CTM-2783S won't turn on


the tv need for servicing, the cause is either bad regulator transistor in the power supply section or shorted horizontal output transistor. that is why the main circuit board doesn't get to turn on. to do the repair just ensure you have knowledge in repairing tv.

No sound, no picture


Hello sorry to hear that. From your description it sounds like your signal board may have been damaged by you plugging in your laptop to it. The signal board is the one with the tuner on it.

Unplug from the wall and hit the power button on the tv. The light may come on dim then fade out or you hear a click. This means it has built in surge protection. Plug it back into the wall and you should be good to go if nothing burnt up.

I have a Sony NSX-40GT1 that won't power on. You can hear the relay click after plugging in, and the red power led comes on, but when you push the power button it does nothing. Any ideas?


I'm having the same problem. Can anyone help. If possible i'd like to fix it rather than go return it. It worked fine for a while and then suddenly started turning itself off. Now every time i turn it on it turns itself off.

TV making chirping sound


If one of the secondary supplies is shorted, the power supply will "chirp" when plugged in. This is the power supply's way of protecting itself and this usually happens when the horizontal output transistor is shorted. If this set was in my shop and needed a new output transistor, a fair price would be right around $100.
