Question about Televison & Video

1 Answer

I have a Phillips Fla screen and a few days ago it started making this loud buzzing/hissing sound that somewhat goes away once the TV is on but comes back with a vengeance when we turn the TV back on i have even unplugged the TV from the wall and the noise is still there, can someone kindly help me please?? I really don't have the money to replace it with a brand new one right now

    it depends on if a board has to be replaced or not---sometimes a part will vibrate on the power board making a sound--seen several where once pinpointed to a single part (usually a small transformer or coil) hot glue can stop the sound.

Most likely if a buzzing or similar sound that is there even with set off--you have a noise coming from a transformer in the standby power supply which is running all the time if the set is plugged in----

Someone would have to open set and listen for it---either a part, a board, or hot glue would have to be used to mute the vibration that is making the sound----one way we locate is with cover off probe with a plastic tool to see where it is.


If you are not able to do this have a tech or a shop "look" for it.

SOURCE: buzzing noise, sound but no picture

It sounds as if the lamp needs to be replaced. The buzzing sound you hear is the ballast attemting to fire the lamp.

SOURCE: Vizio makes loud static noise, picture goes fuzzy.

You should check your home wiring and grounding. Also be aware of anything that has recently been turned on when this happens. Anyone using a microvwave, cell phone, or other appliance that might be causing the interference.

SOURCE: TV won't turn on.

The YouTube video was correct solution for me, i went to Radioshack and bought two (2) 1000uF capacitors 35 wv part#272-1032. I already had all the soldering tools, i used a desoldering wick and my suction tool, the suction tool worked better. after installing the caps, put the board back into TV and turned it on.. all is well so far. i paid $3.44 for the parts. even if you have to buy a tube of solder, solder iron (15 watt max), and de-soldering tool it's still cheaper then repair shop and got nothing to lose even if you are a novice with soldering. :) Good Luck and thanks you guys for the lead on fixing my TV issue!!!

My polaroid has sound and picture problems


This is a well-known problem with many Polaroid FP displays. Eventually, the picture will simply go black, rendering the TV useless. The solution is a new control board, ~$400.

Distortion/noise and buzz in front left speaker


Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.
