Question about Televison & Video

1 Answer

TV making chirping sound when plugged into power outlet. There was a power outage and now the tv is just chirping. I did open it up just to see if any fuses were blown and the only fuse I could find looked ok. TV is only 2 years old and only other problem I have had with it is the input plugs on the front quit working but that was no big deal to me. Any advice? My apartment was without power for 32 hours. When power was restored, My Toshiba 32A14 doesn't start. Instead, there is a chirping noise coming from the back. I removed the back and tested the fuse. It is o.k.

SOURCE: 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.

The only real problem I find with front AV jacks is that they crack loose from the board, because they are subjected to the extra stress of the AV jacks being constantly plugged in and unplugged.

Had a power outage and tv was on when power came back on , heard a pop , now tv has no sound ?


If you have one of the newer flat screen TV sets; power the TV off and then unplug the set from the wall outlet for a couple of minutes and then plug the TV set back in and then power it back up. Lots of newer flat screens have a power supply system that will not reset properly after a voltage spike or a power outage that is a short duration. By unplugging from the wall outlet and letting the power supply drain all the way to a zero (0) setting it usually resets ok when you power it back up. good luck, Dennis

Viore tv won't power up after power outage.


I would first test the outlet. Unplug the TV and plug in your vacuum or other loud or bright object. Turn on test object - if there is no operation, then you have a tripped circuit breaker. Find the electrical panel ( Grey box mounted into a wall, usually in a closet). Find the tripped breaker ( typically the switch will be halfway between on and off, and many have a red indicator by the switch base). Turn switch to off fully, then back to on.
Retest outlet.
If still no power to outlet, unplug everything from that outlet and call an electrician - there may be a serious problem with the wiring!
Hope this helps!!

No sound output need sound unit


Lets focus on the external portion of the TV set first (95 percent of all TV problems are related to things EXTERNAL To the tv itself) Check the physical CONNECTION of all cables by removing each wire bare or RCA and reinstalling it (Each power cable as well), once you have removed one cable, check it for fraying, and if it is already bare, splice a new fresh connection for it. 5. Check to make sure there are NO OTHER uneeded radios, system nearby. these systems, when powered on, will cause electromagnetic interference and prevent more than just severe tv interference SURGE PROTECTOR Surge protectors account for more than 75 percent of electric faults to stereo equipment. Lets start with your AC Wall outlet. It is standard in america that 220 Volts from out of these outlets. This implies that each device will be using 220 Volts (From within that grid zone). If anything including an alarm clock is plugged into any AC outlet socket in the vicinity of the stereo equipment/TV, it will cause electric outage, and prevent electronics from even turning on! Your TV needs dedicated electric power. If your TV is located in the living room then unplug everything else in the living room. Lets plug the TV set into a Dedicated socket. Check all light switches to ensure that power is on for that outlet. Check the TV cable for Fraying both on the ac wall end and where it plugs into the TV. Check all GFCI outlets to ensure that all red reset buttons are pushed in, check the circuit breakers for proper connection and they are turned on. Now, lets try the TV set without it connected to any cable services, vcr, dvd, stereo system, etc.

Tv won't come on


Sounds like the typical power surge created by the outage has caused a power supply problem inside your TV. IF that is it, there not much you can do yourself.
