Question about Hitachi 60V500 60" Rear Projection HDTV-Ready Television

1 Answer

Noisy TV (Hitachi)

TV produces a loud humming sound as if there's a cooling fan that's working extra hard. The problem is sporadic in the sense that it can run for several hours without making any noise and then it can also produce the noise when it has just been running for a few minutes. The temperature light has not come on at all, but the noise is getting more frequent. Is it a cooling fan and if so, is it separate or is it part of the engine assembly(meaning all inclusive)? Any easy solution or is this going to require a professional technician?
PS....we're on our second lamp (replaced over six months ago), the noise problem has surfaced in just the last 3 weeks.

The noise in question relates to capacitors, which are (unfortunately) largely dependant upon environmental elements. You most probably find that when outdoors is wet and humid, there is no issue, but the moment the sun is out and it drys out, your problem rears its ugly head again. This is a basic fault and should be able to be solved by a standard TV tech shop, as its in short, humidity dependant. To explain caps, are moisture based electric storage devices; under normal circumstances the chemicals react ideally to provide the expected volts and or current. Alter the environment subastantially and the cheaper versions will not adapt and they will put the unit 'out of spec' as a dryer environment will produce less volts/current and more humid environment will make it perform closer to spec. Its a sod of a feature but thats earth. :) Higer class ie Class 'A' components tend not to suffer dramatic changes and produce more reliable results.

To sum up, the loud humming is caused by out of spec components or for that matter dried up used up components, the fact it runs for hours at a time is most likely weather dependant and if not its likely to be a dry joint somewhere on the board. These are also unfortunately largely dependant upon environmental conditions. Best of luck. :o)

When we shut the fridge door a loud continuous humming noise comes from the fridge. This seems to be activated by the door light switch at the top. Thank you


There are 2 possibilities I can think of for the hum. When you activate that door switch it activates 2 fans and the compressor. There is one fan located on the compressor and one located in the vent system in the fridge. The second fan is used to circulate cool air evenly through the fridge. I would recommend holding your finger on the door switch and listen carefully whether the noise is coming from inside the back of the fridge or from the lower bottom. Lower bottom could indicate compressor cooling fan or compressor. They would need to be inspected. If it sounds more like the other fan mentioned above it would again need to be inspected. The compressor cooling fans can get stuck or become noisy due to bearing failure. The vent fan can get stuck or noisy but also in some cases if the defrost circuit is not working can chock up with ice and create a buzzing noise as the fan blades strike the ice.

Maytag admiral refrigerator, the fan inside the refrigerator is making a loud sound when on and the cooling in the refrigerator is freezing


Makes sense, you are not moving enough air. Do not over fill the refrigerator. Fix the problem with the fan, if it is noisy I am 99% sure it is not moving enough air. To make noise something mechanical is hitting, it could be either the fan blade (cheaper to fix) or the motor.
Good Luck,

If the fan was not that noisy before , this can only be cause by a dirty fan and you may need to clean it up to reduce the hum coming out from it...
