Question about Polaroid FLM-2625 26 in. HD-Ready LCD Television

1 Answer

TV Fault Just purchased this TV The only way I can describe this fault is that when we switch the TV on it emmits this awful constant humming noise we thought at first that another appliance in the house was causing some sort of interference so we unplugged everything but the noise still remains I can only think that this TV is faulty (NEW) we can obtain a picture and the Audio levels can be adjusted but this constant humming sound is there all of the time. Any Thoughts Many Thanks Pete

    I have the same problem when I plug in any peripheral there is this loud humming; came out of nowhere. Set is about 2 yrs old. Humming sound comes and goes (never completely). When I plug in computer or hdmi connecter sound intensifies. Any answers would be appreciated thanks.

The audio output section of your tV has the fault. The main reason for HUM on output, is due to a shorted audio output IC. Never use the TV, until the fault has been rectified. Prologed use at this state will damge the speakers, and speakers may also be replaced. OK.

Sony STRDH800 emits a loud humming noise cuming throu speakers as soon i switched on and after 3 minuts av reciver switched off byself and blinking protected......plz help

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

Hi there I have recently bought a 5.1 ministry of sound surround sound system but when i connect it via optical cable to my ps3 it just makes this god awful humming sound....Im really disapointed because...

What's the model number? Did it come with a manual and did you refer to it and the PS3 to make sure what you're doing is right?

Describe the source(s) that produce the 'hum'. Perhaps what you describe as "hum" is digital bitstream noise (DTS not decoded). The source is always a player in any audio scenario.

It will not turn on! it turns on an turns right back off?

It is typical fault for most of the sony colour telivisions. Most common fault seen till now is shorted LOT. If LOT is short, normally horizontal output transistor may also short. There is a short circuit protection circuit in the power supply section of most of the sony telivisions, which will detect the short in the circuit , and will turn off automatically as you described. The process will repeat as you seeing now. Each time the power supply will turn on, it will detect the short and turn off. This process will repeat till you switch off the set. At first remove the horzontal output transistor and switch on the set and look for a constant LED lighting. If the LED lichts constantly, surely horizontl output section has a fault, a short. Detect the reason and rectify it.

Dishwasher stopped washing just making a humming noise

humming noise is the wash pump energised but not turning.
this can be:
wash pump seized up
foreign object stuck in the pump impellor.
pump capacitor faulty - a common fault. if pump turns freely by hand but not when energised, then the fault is probably the pump capacitor - cheap part

Matsui dishwasher mf160

I used the solution I found for a slightly different fault, ( this was the same fault but without the bleebs)
switch off mains and turn off water. Then disconnect water pipe and lay machine on it's back. Switch on electrics, and allow water to run out. Switch off electrics and stand machine up .Reconnect everything and hey presto I can hear two good things, the machine gently humming, and my wife telling me what a genius I am !!

Constant humming/buzzing noise

I purchased a poloroid tv 3732 in may of 2005 from circuit city, after about 14 months the set began making a clacking sound and humming sound that gets so loud it is unbareable. I have to turn the set off. I have found out I am not the only one with this problem that has a poloroid tv. I had a technician at my home that told me there is a service warranty on these sets because the wrong part was used and the part needs to be replaced.
