Power issue on a Phillips 50PF7320A

An electricial was working on my house and caused a short somewhere which resulted in a power surge, which in turn resulted in my tv goin out and it wont turn on again. The tv was replaced by the company, but I was wondering if there was an easy fix or would something like this happening have done too much damage to even be worth it.

It is probably the power supply board, it has fuses on it, it can easily be fixed just take the back panel off and check with a multimeter, if good then the board is bad, the last two i replaced cost 200- 250 dollars

Today my power went out for a split second and came back on I turn my TV back on it makes a high pitched whining noise and the screen wont turn on. Cant add picture but model number is MW30G71.


unplug your tv. let it sit for a good bit. 1/2 hour did your power just go out or did you have a power surge then no power. surges cause the grid to go down for a second too and that causes problems too. surge protectors are good for everything. also are you on cable? if so have the cable company check they're filters into the house may be an issue but check the tv after a half hour unplgged and then plug in and turn on normally? sometimes it needs a reset time period before the fuses inside will reset themselves.

HOW TO PROTECT YOUR ELECTRONIC GOODS AGAINST POWER SURGES


I have only been giving advice on FIXYA for a very short while but have noticed that an awful lot of the people who relate their product issues , particularly complain about faults developing after power cuts / outages. It is apparent, from a description of the complaints, that damage is being caused by outages that may be a result of power surges blowing electricity sub stations.
There are a lot of damaged audio devices / tvs being affected. As such I advise you TO BUY SURGE PROTECTORS for all you valuable devices.
I have them around the house and although we only get an occasional power cut here in the UK I know that at times they have saved my equipment fron power spikes. The small cost is justified in the long run.

A power surge zapped my TV, I turned it back on, it tried to bring up the picture but shut off again. A green light keeps blinking.


if a power surge shut down the unit than a circuit, capacitor or fuse is blown and or burnt and you wont smell that most of the time and since it does have power fuse wasnt blown so a circuit -diode-capacitor is fried somewhere problem is common for an electricial damaged tv but to diagnose an electronic tech would need to tear it apart

Why won't my Mitsubishi 73 inch tv come on? Model #WS73411


There may be a circuit board short and component problem that needs a technician to test and repair. This can be a result of a power surge whereby the house power failed and when it came back, too much amperage may have damaged the vital parts on the circuit board. Alwaus use a power surge protector or UPS.

The replacement board could be defective. Your TV worked fine until there was a power loss so its time to troubleshoot to find out how the power loss affected the original board in theTV. There could have been a power surge.

TV will not turn on.


Sounds like there is a short in the tv somewhere, the clicking is probably a breaker/fuse inside the tv cutting power to prevent damage to the components. Have you tried a different outlet as they can sometimes cause this to occur by surging power to the unit.

My dehumidifier is making a power surge every few minutes. why?


A dehumidifier is functionally the same as an air conditioner. It has a compressor motor, which is a fairly high current draw item.

First of all, unless you are well versed in electrical repairs, you should unplug this unit and do not use it. This is a dangerous condition and a fire or electrocution could result.

One of four things is happening:

1) You have a wiring fault in the circuit your humidifier is plugged into. There is a loose connection in the circuit, causing a voltage drop, and the humidifier therefore has to pull much more current to start it's compressor. This is a very dangerous condition, as an electrical fire could result. Try plugging the unit into another circuit and see if it does the same thing.

2) the compressor of the humidifier is going bad and is shorting out internally. Time for a new unit.

3) Many compressor motors use a 'start capacitor' to help the motor get going. If this part has failed, the motor will try to start, but it will not be able to.

4) There is a fault in the power cord or controls of the humidifier. Just like #1 above, a loose connection could cause a voltage drop, making the unit draw high current.

most of these units are standard 110V units. If yours uses 220V (like an electric dryer), then it could have 'lost a phase' which is also a similar electrical issue.

Power to dishwasher


Their is either a Short or an Electricial grounding taking place during the wash cycle. Don't take a chance on buring out your circuit  breaker in the house  panel box . Quit using it until the electricial problem is found.

Power surge issue


This is a fault in the motor, could be a shorted turn in the motor windings. This has nothing to do with fuses.

Blinking red light


If your Sony TV is hooked up to a good signal and is set up correctly, but only clicks and has no picture or sound, and even the menu will not show up on the screen, then it means that the main power supply has stopped working. I usually find that a small crack in the solder joint of the horizontal drive transformer or a shorted flyback will cause the large horizontal output transistor to short out, and this shorts out the switching transistors in the main power supply which then causes the Sony 0.1 ohm fuse resistor to open up. I have also seen power surges or power failures (brown-outs) cause the switching transistors to short out. In any case, the set absolutely should be serviced by someone experienced in repairing Sony TV's.
