** TV won't turn on.** No picture or sound. Please Help !


If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

I'm trying to fix my 21 inch JVC TV, its on standby mode i detected the problem it was Horizontal output transistor, when i replace it with new one it work but after 24 days it got shorted again so i...


depending on circuit design in some TVs when flyback becomes defective then (1) only flyback gets deffective or (2) flyback & 1 transistor big in size fixed near flyback gets deffective or (3) flyback,big transistor & resistor or diodes or some times ICs will get deffective ..........so flyback replacement is compulsory + which ever components gets deffective ....... usually flyback gets deffective after 4yrs (between 4yrs to 12 yrs depending on TV brand & usuage ) .............so in your case along with horizontal transistor replace flyback also ..................... Remove that flyback from main board ? using marker make a mark (1 dot on knob & at the same line put another dot on flyback --- these 2 dots should be in same line ) on all the knobs on fly back ....now turn all the knobs one by one in anticlockwise direction slowly until it stops .... Then observe from the mark which you made before turning .. --- you will get an idea which knob howmuch it was turned in anticlockwise direction.... now take flyback to electronic shop & buy same type ( equivalent will not work )......at the shop itself check part number , number of pins & their position of old flyback with that of new flyback ----- everything should match 100% - nothing less nothing more .... it should be exact .... check many shops...now turn all the knobs of new flyback in anticlockwise direction very very very slowly until it stops....now fix it to mainboard very slowly & carefully....don't forget to connect red wire from flyback to TV TUBE ...again iam repeating don't forget to connect red wire from flyback to TV TUBE .... Now observe mainboard carefully whether any connector is not connected ....now connect only tv powercord & stay at a distance & switch on Tv for 2 seconds & then switch of immediately....during this 2 seconds TV gets on & led also gets on continuosly (won't blink) & there should not be any smoke or sounds on main board ...this confirms you have replaced flyback without disturbing other components & not shorted any joints..... so now again switch on tv ..wait 3 or 4 seconds ...led will be on but there won't be any picture ... Don't worry ....in the beginning you have observed howmuch knobs on your old flyback were turned in anticlockwise direction....remember..? see your old flyback again.... Now using suitable screew driver turn all the knobs on new flyback in clockwise direction one by one very very very slowly ...untill as it was in old flyback ( approximately ) --- remember TV is in on condition ... means high voltage will be there ... bymistake if you touch any part of the tv .. you will get very severe shock.... So be very very very carefull ..now while doing this adjustment observe what is happening on the screen - how brightness is changing ... Now switch off tv....connect signal ( antenna or dvd or cable..) & again switch on TV ....so now depending on brightness & clarity of the picture ..looking at the tv screen again you have to turn 1 or all the knobs on flyback either in clockwise direction or in anticlockwise direction very very very slowly ..once you start doing this adjustment practically then automatically you will come to know which knob should be turned . in which direction - & howmuch it has to be turned .... But remember this adjustment is very important .. Sometimes it will take 30mins to finalise the exact position.of knobs .. so take your owntime & finalise the exact position of those knobs..then switch off tv ..fix back the tv cover .. then switch on tv again ....that's all .......100% GUARANTEE again your tv will work normally ....vishnuswamy_23.jpg

My amp will turn on and even when I have the guitar and amp connected no sound comes from the amp. I don't know what to try to fix it, so I have left it alone, testing it every once in a while (it...


Possibly a loose connection, or bad solder connection. unplug it from power.

If you think you are up to it geta soldering iron and some solder, and a screwdriver, and take the amp part out. be careful of the speaker wires. put some tape on each one and label them so you know where to put them back. after you got it out you might have to take some more screws out to get the board off of the chasis, so you can see under it. this is where all the components are soldered to the board. maybe use a magnifying glass. touch up anything that looks questionable.
do all over. you don't need to know what everything does if you just go all over. careful not to cause any shorts. you might see something that obviously needs to be fixed. you have found a problem. you can't fix something if you don't find a problem. do all over anyway if you think you still have to.

Put it back well enough to test it. then put it all the way back together, or continue to look for a problem, or take it to someone, like me!


Good luck

Hi, Sorry we don't know it either. Unplug TV for 1 hour and then try again. Sometimes unplugging will reset the TV. I hope it did for you. Good luck.

Toshiba 32a33. I'll be watching tv and the volume bar shows goes down to 0 (no sound) when it is in this mode the remote control will not work on the volume, you can get up and manually up the volume...


1st check to see if your remote volume down button is stuck. 2nd do you have wireless internet (router) or any other wireless devices phones,ceiling fans, another Toshiba remote, if so try unplugging them (or remove the batteries if it's a remote) while it's changing the volume one at a time. If a different device makes it stop try changing the channel on it. Also make sure the t.v doesn't have a mind of its own and remove the batteries out of the t.v remote, let it ride for a couple days if it happens without the remote being in play then you know your t.v is acting strange, if it stops then starts back up when you start using the remote again then you know your dealing with a remote issue. Sometimes Freq.'s merge causing remotes/wireless devices to conflict with each other.
