I wish there was a ONE answer fits all manufacturers have their own unique opportunities.

The most common problem in UPS'S are the batteries going "dead"...which may or may not damage the following 1. The fuse for the batteries 2. The battery charging circuit.

Hope this helps

In onida ky thunder strf6654 getting burn,fuse blown when also change of str.????

Check all the associated components at the power supply regulator section circuit; especially check the zener diode/s. Replace them. Replace the STR only after replacing these components. There is a chance to these components too can damage, when the original STR has burned out by any reason. If you wish to get more, about the schematic diagram; check the site linked here. Type in the number of STR in its search box, or Pull up previous posts, either by type in the Brand name to your set in its search box, or view it in Mosaic / Timeslide / Flipcard option.

If you are trying to view TV channels, you might have to run a channel scan, check your user manual to see how to do a channel scan. Or just go into the menu and I'm sure it is there under channel setup or some name like that. I hope this helps you.

Can't find a fuse replacement...

We can't predict which components have been damaged due to lightning. Sometimes, a fuse only, otherwise more other components might have damaged. Anyway, if fuse should blow out, surely there will be any more reason. You should find it out first, before replacing the fuse. If not, more damage can be occur. Check for any shorted components, diodes, capacitors etc: at its main power supply regulator board. Be sure that there is no other defect occurred.

My harman kardon avr 520 shorted out. i see 2 fuses blown 1 slow burn 7a 250v slow burn & 1 slow burn 2a 250v 5x20mm. Is this a good place to start fixing it? i had metat to metal shorting because of...

The output transistors are most likely shorted and need to be replaced. Since this was a short caused by user action, there is a high probability that other components further back into the circuitry is also damaged. This is not a repair that should be attempted by a homeowner. Incorrect repairs can cause further damage, so I would suggest that you at least get a repair estimate from a local shop. If you have any electronics experience, we can then perhaps guide you through the actual repair.

Please keep us posted.

We had a lightning strike close by and now the TV will not turn on. Is it possible that there is a fuse that is blown?

It can't predict what may have wrong with your TV; becuse the lightning stroke will have trillions of volts when it strike the earth. Even its near presence will spoil the power supply section of any equipements. There is surely a fuse inside it, and you can check after opening the TV. Check it first. If it is burned, make a visual check inside the components of the TV for a burned damaged if any. If you find any of it, please do not put an other fuse and make an experiment with the TV. it may cause more components to be damaged. If no visual burned componets are seen, just put a fuse of same ratings [ratings will be either printed on its rims or indicated by colour bands across it]. If the replaced fuse again gets burned as the set is switched ON, make sure that some components in the power supply is shorted, and a through checkup should be done. Contact any experienced service technician to do the work. OK.

My Samsung Tv turns on but cant see picture how do i fix this?

we need to isolate this simultaneously, you must remove back cover and visually check for burn parts. (warning for the high voltage pin) if you can take pict. ckt side the better for us to trace from power supply board to horizontal section. let me know where we can start for analysis.

Blown fuse

Continued replacement of fuses without fixing the reason for them blowing MAY be doing additional damage to components in the unit.

It needs to go to a repair shop. It is likely there is damage in the power supply section or that of the power amplifier section.
