Pop fuse when pluged in

Everytime I plug the tv in it pops the fuse on the power input. The television is a model # F35100ST. The previous owner tried to tell me that it was the high voltage trasistor, but I think it might be something else. Please need advice as to how to fix this problem myself if possible

Yes it may very well be the horizontal output transistor or the voltage regulator ic or a shorted rectifier diode on the power supply or the b+ capacitor on the powersupply good luck

The fuse pops when I plug in the set. Otherwise there is no power.


Does the fuse pop even when you have the TV off? If so, it's most likely it's a short in the power cord. Examine the cord closely, and see if there are any breaks in it. If you have a voltmeter, see if you're getting much resistance if you put one tip on each prong of the plug (while it's unplugged, of course). You should have infinite resistance, while the TV's off.

It could be something within the TV's power supply, but I think a damaged cord is more likely (and it's MUCH easier to fix, just cut the cord and splice a new one on). If you're sure it's not the cord, check it again... and if you're still sure, let me know and we can delve into the difficult things that are less likely, but possible, to be the cause.

Lost all power in 1991 RCA TV model F35100ST


Best thing to start here is open up the TV and look for any blown components on the power board (which is the one that has the power cable attached to); check the transformer for continuity first, that is the first thing to blow. Then go on with capacitors, resisters, and any burnt wires.

All of these parts are easy to find and replace, they can be found in local electronics shops.

Please post back how it went and any further information or questions you may have, so we can help you better.

Good luck!

Roku stick dosent do anything. ...? Plugged into hdmi slot on tv and also plugged in power cord to roku and nothing pops up on my tv...? Iv tryed to reset but dose nothing. ... help???


Did you change the TV input setting on your TV to the correct HDMI input? Most Televisions will take a few seconds to scan the input before displaying any image. Most newer televisions have multiple HDMI inputs, and you might need to select each one, wait several seconds to see if there's a signal, and then move on to the next input, until you find which HDMI input has the Roku start screen signal.

Hi,Iwas watching TV and the screen went black.No lights on,I unplugged and plugged again but anything happened. My TV is a Toshiba Regza model 42RV530U. Can you help me? Thanks


If there was a popping noise of any kind when the tv screen went black there's a high possibility that one of the fuses in the tv popped and there is no power to the tv. It could also just be the outlet itself and try plugging the tv to different working outlets.

Pops power supply fuse when I plug it in


Check to fuse box to see if the fuse is working properly. Next, see if the TV "pops" the power supply when pluged into a different outlet in a different power supply area. If the TV works without poping the fuse, the fuse with the original outlet needs replacing. If both outlets "pop", either the electrical system needs checking. Or if this is a new problem that started when you first tried the TV, the TV could be wanting more power than the electrical system will allow. Check the power requiremnets in the TV manual.

TV will not turn on


Assuming you are absolutely sure the TV is getting power,
If you have an ohmmeter, measure the resistance between the two prongs on its plug. If no conductivity (over 1 meg Ohm) the fuse inside is popped. Take the cover off, look in the area near the power cord, it is the usual 5AG type (glass cylinder) fuse. If you replace it and it pops again then measure all the diodes in the rectifier circuit (near the fuse).
Many times power transients will just blow these input power devices. However, many times it will go much deeper and get the TV's processor brain. If the TV is anywhere near 10 years old, I wouldn't go any deeper than the input power circuit.
