Why won't tv turn on by remote or power button unless we try 4-5 times?

My TV has the same problem.
At first, it was an issue with the button itself, somehow some gunk got down under the button and kept it from pressing down all the way most of the time.
A few days after we fixed that, it started to mess up again, this time it was an issue with the way it transmitted signal to the TV.

If the button being blocked isn't the issue, replace the batteries. If the batteries aren't the issue and you don't have a soldering gun, then you'll need to purchase a new remote.

I bought one from walmart for ten dollars and it works just fine for basic use.

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 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 ) 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 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 ) 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 turn all the knobs of new flyback in anticlockwise direction very very very slowly until it 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 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 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 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 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

Sstandby light blinks & doesn't turn on.

Television will not turn on consistently


There are far better experts from this site who would know more if you can post back specific model no or preferably the Chassis no. of your Toshiba.

Just to start the ball rolling, to my knowledge, most models of CTVs since a few years back uses an internal mini computer. Like any computer it does need to be reset and in your case, unplugging (actually for a few hours) performs a hard reset . For a few minutes is a soft reset.

At times, the standby led or power led would also flash a certain sequence to indicate if there is an internal fault detected by the protection circuitry. By unplugging, you did a reset on the protection circuitry and if your problem is intermittent or develops over a period of viewing time (chances are heat related problem), then the protect will auto activate and will not allow power on the next time (if the unit is plug).

Hope that this be of some initial help/idea. Please post back and I'm sure others would be offering detailed assistance thereafter.

Good luck and kind regards.
