Question about Proscan 32LA30Q Television

2 Answers

Humming After the TV has been turned on for about 15 minutes, a loud humming will begin. It only happens if there is sound flowing through the speakers. If I mute the TV, the humming goes away. I had exchanged it for a new one, and the new one still hums.

    I have the same problem, I also tried using the TV as a computer monitor with the same results. But if the volume is turned all the way down the humming quits! It does not matter where the TV is plugged in or if other items are plugged in with it!

Hi,

More often than not, the humming sound on any electronic device is brought about by the AC side of the power supply not only of the device itself but also all other equipment it is attached to. In your particular case, it maybe introduced into the system from:

  • (coaxial) cable TV leadin;
  • connections of DVD, VCR, game consoles and others;
  • electrical noise from lamp dimmers, lights with electronic ballasts, wireless phones.
It is interesting to note, that the noise could be from other appliances plug in the same circuit as the TV, you of course could try plugging it into another outlet or branch. In some instances, you could even try filtered regulators similar to those used by desktop computers.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Humming sound undercar


Does this happen at all while turning the car? It could be a hub bearing. Just replaced mine and it was a humming sound. It would be pretty loud around 15 to 40 mph but got quieter after that.

As these units get old, the solder joints can start to fail. Also, come of the components are getting tired. If you have no electronics experience, bring this to a servicer. I typically overhaul these units for about $100 plus parts. In most cases, the parts costis less than $20. These are solid units and you can probably get another 30 years out of it.

Part of the overhaul should be reseating all of the output transistors and replacing all of the heatsink compound as well as cleaning out all of the pots and switches.

Keep us posted.

I have a 42 inch Hitachi plasma tv that is making a very loud static noice coming from the internal speakers. It stays at a contstant very loud volume unless I completly mute the tv or turn the volum


Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.

A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?

Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.

Toshiba 62HM195, Loud hum noise when TV is first turned on.


I have the exact TV and had the exact same problems. It is the light engine with color wheel that needs to be replaced, and they are VERY hard to come by for this model. Our repairman has had our TV for 5 months and still cannot locate a vendor that carries the part. He said according to Toshiba, the part has been discontinued. If you happen to find one, please post. I'll do the same.

Loud humming sound coming from TV speakers


I believe this is a dirt and contamination issue within the PS2. You need to open the case and thrououghly clean it out. This means thoroughly, Motherboard, and all. You will need a can of circuit board cleaner.
