My t.v. will not power up or turn on

Once I turned off my t.v. it won't turn back on. I've checked one fuse and it didn't seem blown. is there any other fuses? It worked great until this. I usually leave the t.v. on all night when i'm at work. i've been doing this for about 2 or 3 months and then one morning i turned it off and that was it,nothing more.

Won't turn on after power outage


It is hard to diagnose a set if I don't have a brand name or model number. But if this happened after a power surge, then you could just have a blown fuse. If the fuse doesn't fix, then your problem lies in the power supply somewhere.

My pansonic tv model ct-13r37s won't turn on by


if their is no any power indicator at the front panel the cause is either the primary fuse at the power supply section blown. and then if the fuse is blown that was mean the regulator transistor and the horizontal out put transistor could also damaged. this case can be hand held by trained technician. if you want a do it with your own just make sure you have at least a basic knowledge in electronic repair since you are dealing with some high voltage parts a care must be needed.

What's your problem?the tv won't turn on i check thehorizontal trans and its fine i check the power and everything but nothing


Check the horizontal driver transformer. Measure the frequency at the base of horizontal output transistor. It should be around 15.6 KHz. If there is no frequency measured at this point, horizontal driver transformer, horizontal driver transistor, and horizontal oscillator section should be troubleshooted.

Tv won't turn on


Hello
Chech whether AC power get into the power supply regulator section. Just open your tV, and check it. There is a fuse [ glass cartridge type] on the power supply section. Check whether it has blown up or not. If blown up, make sure that there is some shorted components at the power supply section check it.

Sony 6060F blown fuse


hello!
there is a standard procedure for proper replacement of blown fuse: CRT TVs: unplug degaussing coil, replace blown fuse with 2amp fuse and turn on the set. If it works, reconnect degaussing coil, replace the fuse with correct value(5-8) amp, depends on model(see fuse note next to holder). Enjoy the show! If in a process of replacing the blown fuse with 2amp w/o degaussing coil it blows again, forget about the next step. Set need repair. It could be an easy one, replacing 1 or 2 shorted diodes or bridge rectifier, but could be real piece of work if the power supply got "fried". If your knowledge won't go further, than fuse replacement, I'd recommend local TV repair shop.
good luck,
Alex.

After a lightning storm, my TV will not turn on. Is there a fuse or something on the in coming power that may have blown causing it not to turn on?


Any TV subjected to a power surge will have problems. If you can remove the back cover, do so. Locate the glass fuse. In the best situations the fuse is clear and opened, and replacement will repair your TV. In worst cases the fuse may be blackened, and you will see that many components are burned and shattered. If this latter is true, only replacing the TV is your best bet. In many cases electronics may be connected to surge protectors, but lightning will over ride these devices and cause damage. I have seen this happen many times.Thanks for asking and show all hands of support!

It could be a blown fuse, sometimes when power is restored a power spike occurs this can blow fuses in appliances. Check power to either side of main fuse. Then progressivly check all other minor fuses Cheers Paul

Tv wont turn on


Hello tvlover, The outage actually is not the problem but the spike that happened when your power came back on did the damage. That aside, you may just have a blown fuse. If you are able to and feel comfortable work with electronics, with the TV unplugged from the wall, take the back off of your TV and take a look at the line cord going into the circuit board, this will lead you to a fuse holder, look at the fuse and see if the filament inside has been blown (opened). If the fuse is blown relace it with one of the same amperage and voltage which should be written on the metal part of the fuse. Once the fuse is replaced, plug the power cord back into the wall and power it up. If it comes on and plays, that was your problem and you can turn the TV off unplug it and put the back cover back on, plug your TV back into the wall and enjoy. However if the fuse blows again, that could indicate a problem with a short somewhere in the powersupply path and that will require troubleshooting the set. Now I we have to troubleshhot this TV you will need a multimeter, an oscilloscope, and a schematic of the TV (at a minimum). If you do have electronics experience to this level and do not have this type of equipment, You will have to take the TV to a repair shop. Thank you, and I hope that it is just a blown fuse.
