There are fuses and MOV's to protect for surges.
mov is metal oxide varistor, a resistor that shorts out when the voltage rating is exceeded causing the fuse to bluw.
always right after the fuse on the circuit board on the powersupply board

Surge protector was blinking. smelled a little electrical burn odor. pluged tv directly to wall..all I hear ia a click noise..nothing lights up . help!


The surge protector has likely committed suicide... or died by homicide. In other words, it may have done its job, or been fried trying. Either the breaker/fuse inside melted by design due to a surge, or it died.

A surge protector is only designed to protect you from many small/everyday surges, or ONE BIG ONE. The cumulative wear of small surges will eventually kill them as well. They don't last forever, and some experts recommend replacing them every 3 years or so for safety/performance.

Some surge protectors have a reset switch or a replaceable fuse, but since you smelled something burning, I highly recommend tossing it in the garbage (if not still on fire, hee hee), and get a new surge protector for safety. Your house is worth the $25+. If you have had any other electrical issues in your home lately, get an electrician to do a quick safety inspection as well. Be safe!

PS: Not all surge protectors are created equal. Look for one that has "lighting protection" and costs at least $20-25 , or you likely don't have decent protection (the ones I buy are usually $30-$35, but I watch for sales and keep an extra on hand). Never overload a surge protector or wall outlet. Read the manual for the total watts,etc. supported. And don't expect to collect on the $50,000 equipment damage guarantee some surge protectors promise.

How can I get Dynex TV out of "protection mode"?


the protected mode kicks in when there is a safety issue with the receiver. This usually comes from an overload to the system via a short in the system or perhaps a surge in power. Your receiver shuts down, and you'll need to shut the entire system down to fix it.
In some older homes, some of the wiring doesn't deliver the "cleanest" power, delivering minor power surges to the items you plug directly into the wall. If your receiver is plugged directly into the wall, purchase a surge protector to stop this

Samsung LE32A4566C2D flat screen tv wont turn on?


There is a chance the power supply is fried. However, I've seen some Samsung power supplies that have fusible resistors in the power supply for added protection. So your main fuse could be ok, but there could be an additional fusible resistor in the board as well. Also be aware, depending on where the surge entered the TV, you could also have a defective main board. Not trying to rain on your parade, but surge damage can sometimes be severe.

I THINK I JUST FRIED MY WII THERE WAS A POP NOISE AFTER A POWER SURGE IS THERE ANY WAY THAT i CVAN CHANGE THE FUSE OR IS MY WII FRIED FOREVER?


i have had some experience in taken apart a wii before to modify the case and i never noticed a fuse inside i know some systems (not sure if hte wii does) have a built in surge protection and to reset it you must unplug it from the wall for some time and then plug it back in. But i do fear you may have "fried" your wii.

Tv does not turn on after a thunderstorm and several attempts at power returning to the home. The power went on briefly then shut off several times, now the television will not turn on. We had the tv...


Check the main fuse in the power supply, the TV also has small surge protection devices (MOVs) installed after the fuse, any surges the come along and big enough will cause the main AC fuse to blow. When you surge protector, EVERY connections must go through the surge protector, for example, the AC cord of the TV is connected to the surge protector, the cable connection did not go through the surge protection, the surge then can get to the TV through the cables.

Talk to Sylvania about your TV. If your TV is fried (if it's off it's still vulnerable) they MIGHT be nice and replace it. I recommend you protect all your electronics with surge protectors, since they'll help you should this happen again.

Power surge or electrical outage tv blue light stays on with humming sound no picture


Hello,

Power surges or nearby lightning strikes can destroy electronic equipment. However, most of the time, damage is minimal or at least easily repaired. With a direct hit, you may not recognize what is left of it!Ideally, electronic equipment should be unplugged (both AC line and phone line!) during electrical storms if possible. Modern TVs, VCRs, microwave ovens, and even stereo equipment is particularly susceptible to lightning and surge damage because some parts of the circuitry are always alive and therefore have a connection to the AC line. Telephones, modems, and faxes are directly connected to the phone lines. Better designs include filtering and surge suppression components built in. With a near-miss, the only thing that may happen is for the internal fuse to blow or for the microcontroller to go bonkers and just require power cycling. There is no possible protection against a direct strike. However, devices with power switches that totally break the line connection are more robust since it takes much more voltage to jump the gap in the switch than to fry electronic parts. Monitors and TVs may also have their CRTs magnetized due to the electromagnetic fields associated with a lightning strike - similar but on a smaller scale to the EMP of a nuclear detonation.
Was the TV operating or on standby at the time? If it was switched off using an actual power switch (not a logic pushbutton or the remote control), then either a component in front of the switch has blown, the surge was enough to jump the gap between the switch contacts, or it was just a coincidence (yeh, right).
If the TV was operating or on standby or has no actual power switch, then a number of parts could be fried.
TVs usually have their own internal surge protection devices like MOVs (Metal Oxide Varistors) after the fuse. So it is possible that all that is wrong is that the line fuse has blown. Remove the cover (unplug it first!) and start at the line cord. If you find a blown fuse, remove it and measure across the in-board side of fuse holder and the other (should be the neutral) side of the line. The ohmmeter reading should be fairly high - well certainly not less than 100 ohms - in at least one direction. You may need to unplug the degaussing coil to get a reasonable reading as its resistance may be 25 or 30 ohms. If the reading is really low, there are other problems. If the resistance checks out, replace the fuse and try powering the TV. There will be 3 possibilities:
  1. It will work fine, problem solved.
  2. It will immediately blow the fuse. This means there is at least one component shorted - possibilities include an MOV, line rectifiers, main filter cap, regulator transistor, horizontal output transistor, etc. You will need to check with your ohmmeter for shorted semiconductors. Remove any that are suspect and see of the fuse now survives (use the series light bulb to cut your losses
  3. It will not work properly or appear dead. This could mean there are open fusable resistors other defective parts in the power supply or elsewhere. In this case further testing will be required and at some point you may need the schematic
hope this helpout......

Jamo i300 speakers are dead.


There is peobably a fuse located on the back. Your speaekers are probably okay. If anything fried inside, it is probably the output transistors.

Power Surge at Home


This time it came in on the cable, the clue was the cable box also blew. So if you had a cable surge supression device...for HDTV, I think you would have survived the second surge.

I do have the technology. It is a F-connector type and will handle HDTV signal.
