Noisy flyback transformer tcl CRT TV model 14F1

They often begin buzzing when the oil inside them gets old or evaporates from a cracked housing. It needs replacing however be very careful. Flyback have 50000 to 100000 volts in them even when the tv is off. There is a safety discharge procedure however if you are not familiar with replacing a flyback do not attempt it yourself. FLYBACK TRANSFORMERS CAN SEVERLY INJURE OR KILL YOU.

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

My jvc av-32890 makes a click and shuts off 95% of the time.It will not stay on and when it does it is only for a few seconds.

maybe your flyback. check b+ on the flyback. If you dont have voltage you can unsolder b+ pin on flyback and feed a 75 watt lamp to verify if power supply or flyback trouble.I think it`s pin 9 on flyback. look for print b+ on pcb.

Toshiba 32'' tv no power no sound red led in front on and blinks also hearing hissing from flyback model#cx32f60

for sure your tv has power as indicated by your flyback hissing it also indicates leaking high voltage that might destroyed your vertical or any other parts near your flyback ,the flyback itself should be replaced for its high voltage arcing can ruin so many components

I was told tthat the flyback is bad on my toshiba tv model #CF36G40 can i replace the flyback myself? Is there any adjustments that need to be made after replacement?

Stay the hell away from a flyback. It will knock you clear across the room! The only thing I look for in a tv is an internal fuse, and then I look very carefully. If I don't find a fuse, I toss it.

36" RCA- loud whine/squeal when it is plugged in, otherwise no power.

The HOT Hortz output transistor has gone home, 99% of the time from a faulty IVHT (Flyback Transformer), very common on the ctc187cl* chassis. The factory Flyback is no longer available, I have had problems finding an aftermarket one to replace it with.

The HOT is a BUH517, but you can also use a 2SD5129. It is the transistor mounted on the siler heat sink with a metal clip rather than a screw, just in front of the flyback.....

If you replace just the HOT, most of the time you will get a rapid arc (27,000volts - BE CAREFUL!!!) from the lower (yoke) post on the flyback. If the flyback is shorted, It may also just burn out the HOT and go right back to "squealing"....

Good luck finding the flyback!!!

Tv showing blue screen with flyback lines sound ok

Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket
