Question about RCA 27V520T 27" TV

1 Answer

Power surge tv had a power surge go through it and now I cannot turn tv on. My tv does not power up as a result of an outside wiring problem. There was a broken ground wire from the pole to the house, which has since been corrected. The tv was plugged into a surge protector, which did NOT trip. I replaced the fuse and still have no power. There was a second tv similarly afflicted and changing the fuse fixed its problem, as did changing the fuse in the surround sound system that was on the same surge protector as the RCA tv. The model is 27V520T. Is it permanently dead or is there something else I can swap out? Thanks.

I have a flat pannel 60 inch sharp aquos that won turn on

Usually it is a power supply problem, so check voltages, 5V circuit is usually the culprit caused by leaking capacitor, so you have to look closely at tops of the large capacitors on power supply board and if top is swollen, that is problem, very typical in all flat panel TV's, cheap fix for about $6.00 if you have solder gun.

Good luck. FREE-PPV

Samsung HLN617w won't turn on

How old is the surge protector you used? Because they only last for so long and can absorb so many surges. I hate to say it but it sounds like your TV sustained a power surge.

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.

There is no reset button outside. The main power supply regulator section [SMPS] should troubleshoot. Contact any service technician. If you wish to get some details, check the site linked here. Pull up older posts.

I have an Onkyo RT-R390 Receiver that will not turn on. It just makes a load clicking sound when plugged in.

The sound is the AC input protection relay kicking out due to a high input current surge when the unit is turned on. The work on the lines outside killed your amp. Homeowner insurance usually covers this type of damage less deductible. Call, its free. Contractors lifted your ground reference or live phase before turning off your panel. 1_5_2014_5_02_39_pm.jpg

My 65 in tv shuts off on its own not all the time but too offten

That's a result a power fluctuation from your power source. The TV is designed to do that. Could be the result of faulty surge protector or something in your home's wiring. I've had it happen maybe half a dozen times since I've had mine (01/2009)

Constant beeping

sounds like your selection sensor has got a wire broken. if you look at the wire bundle coming off of carrier, three of those are for selection sensor. 1 blue, 1 red, and 1 black. one of those are most likely broke from continuous movement of carrier back and forth. common problem on this machine. that repair would have to be done by a tech however, as it is not easy.

All TV's in house failing, a few at a time

Hey PNorris,

If multiple electronic devices are failing in your home all at once, I would probably first have to ask if your home recently experienced an electrical storm or major power surge of any kind.

Normally the effects of such large-scale surges are immediately noticeable - TV's and other major electronic devices may fail to turn on, fuses may be blown or circuit breakers tripped, and in some cases electrical wiring may be melted.

If nothing like this has happened recently, low-level power surges may still be a potential cause of this problem. When the motor from any large appliance (such as an air conditioner or refrigerator) turns on or off, it often diverts power to and from other electronic devices using the same circuits. This fluctuation in electrical current may result in low-level power surges to every connected device. While not immediately noticeable, these low-level surges can often cause the eventual failure of (and gradually degrading quality in) many audio/video components.

Typically, the easiest way to avoid situations like this is to make sure that outlets are not overloaded and surge protectors are used with every major electrical device in your home. For older homes however, replacing the house's wiring may be necessary. Homes that were originally built at the turn of the 20th century may not always have wiring capable of supporting the electrical needs of many modern appliances.

Ultimately, this means that in addition to contacting your local TV repair facility, you may want to also speak with an electrician. This is probably the best way to determine whether or not power surges have caused these failures, and may give you a better idea how to proceed.

Hope this helps you out.

Go Ahead. Use Us.

Loses electric

Get a voltage meter and see if you have 110-120volts ac at the outlet. If the lights and/or a bathroom fan have any feedback they could lower the voltage to your TV and it may have a low voltage safety relay that turns off the TV when low voltage is present. This happens in older homes. If this home is older this little problem may be telling you that the wiring in your home is old and in need of replacement. You do not want a fire.
