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.

Loud pop from surge protector that results in intermittent sound on Samsung 46" tv

I hope the surge protector is separate from your TV. It has Varistors in it that are supposed to pass overvoltage surges (it can happen without the power going out) then recover to normal. But sometimes they overheat, then they can become a fire hazard. Or the contacts in the sockets can get charred and flakey. Anyway sounds like it is fried, the only easy solution is replace it. A careful tinkerer with a good scrounge box could fix it, if you know anybody like that.

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.

Following a power cut my tv has no power, have changed the fuse, checked and used another proven working plug and still no power .. Is this tv repairable ?

Sounds like the power supply has copped a mains-borne surge. Replacing the fuse doesn't always fix it unfortunately. The cost to repair the switchmode PSU depends on how many components have been affected within it and the extent of the damage as a result of the surge. If the damage is serious, for example burn marks/large cracks on the board, and the optocoupler is destroyed, the whole set would be uneconomical to repair.

You can never predict when or where a power surge is likely to strike.

We got a power surge last night, now the TV will not come on. The red LED located in front of TV indicates power coming on pressing button but will start blinking monents later.

Possible that the surge had resulted in the SMPS- switch mode power supply - giving a higher output before it would have corrected but had resulted in the failure of some component.
Remove the panel if you can start the work armed with a multimeter, the mains power being put off. wear insulated slippers while probing the circuits specially when the power is switched for voltage checks.
first of all check the main power unit :click for tips on SMPS
If there was no fault noticed visually then check the processor controller section specially the voltage to the processor. If the +5 volt is missing check the regulator or the feed.
If there is power then check if the mP activates the HT circuit, if not the main board had errors to be looked into with a trace of the working voltages, look specially for charred or damaged components.

No power either!!

Unplug the surge protector and plug the tv in directly to an outlet that you know is working, plug something else in first to be sure.

you may find that your surge protector is shot. if it is toss it and get a new one.

32 '' CRT won't turn on afer power surge

Follow these steps to troubleshoot the television not turning on:

Make sure the AC power cord is connected securely to a working wall outlet.
NOTE: If the television is plugged into a power strip or surge protector, unplug it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

Press the POWER button on the television.
Press the POWER button on the remote control that was supplied with the television.
NOTE: If the television turns on and off using the POWER button on the television but does not respond to the POWER button on the remote control, troubleshoot the remote control.

Unplug the television power cord from the electrical outlet for 30 seconds.
Plug the power cord back into a known working electrical outlet.
Attempt to turn on the television.
IMPORTANT for the following models only:

Unplugging the above television models from the electrical outlet may only be a temporary fix. The problem may reoccur after several months of use. To completely resolve the issue, a software update is available.

For all other models, service will be required if the troubleshooting steps do not resolve the issue.

We had a near lightning strike and now my tv (sanyo model ht27744)doesn't want to come on.

Lightening may have caused a surge on your power lines to the house and to the outlet the TV was on.
Do other things work on that outlet? If not you tripped a power breaker.If they do work check this.
Unplug the TV for 2 min or more and plug back in.
Try bypassing your surge protector you had it plugged into. It could have died when the lightening struck.
(no surge protector?) Bet you'll buy one for your next TV.
Look for 3000 joules and up rating for a surge protector and insure it has protection for a cable/antenna input too.
If this doesn't work the TV may be fried or internal fuse blown.
Time to take it to a repair shop or depending on it's age (5 years+) it may be time to buy a new TV and surge protector.
Near Lightening strikes can effect appliances from several inputs that could be affected from outside like Power, Cable, Antennas, Phone Lines that come into your house.
