If you think a power supply is okey, do you hear oscillation sound. if you do change a line transistor and observe.
if does not work contact me, again

My sony kd36fs130 wont turn on .the green power light clicks then the light dims ans I can hear a tv coming on sound but stops when the light dims


From your description the flyback transformer has failed causing the high voltage to load down, if the TV is 10 years old or more, consideration should be given investing in a new set.

I push the on button the red light comes on, tv makes clicking sound, screen does nothing. TV has no static. I checked fuses. what should i do next?


If it is a CRT type tv. Could be the start up circuit is failing. Check it using remote to turn on the tv. If nothing happens check the fuse if ok, then you may have start up problem or, faulty high voltage section. But clicking sounds may indicate you have standbye voltage.

If you can isolate the B+ supply you can check the specified voltage if whether in spec. Then if ok then Horizontal output transistor or the flyback or other minor component like diode and the capacitor.

If you are not inclined on electronics better not mess with it. It will bite. Have a repairer check that.

Set wont turn on


^.^ hi..
I see that your TV's high voltage flyback is leaking out.
or the flyback cap to the CRT aka picturetube is dirty, or it has a open insulation.
(Warning: Flybacks are extremely dangerous, it has a high voltage that kills. becareful.)

Good day.
Flyback could sometime be a problem but seldom that its the source. Have your circuits be checked first particularly the vertical section. Also, check on the supply of your system IC. there may be some imbalances there.

Response is highly appreciated.

RCA 32" wont turn on


It sounds like you may have a bad Horizontal Output Transistor (HOT) and/or a bad Flyback Transformer. The set is trying to start as indicated by the flashing light, but an internal fault is shutting it down right away. It could also be the Power Supply circuit. A 32in. set is not cheap to replace so it may be worth finding a repair technitian and at least getting a quote. The Flyback is the most expensive part, the others are minimal. If it is one of the above problems it could easily be repaired by a qualified technitian.

Tv wont turn on


The green light indicates that it is getting power from the outlet ok.
The clicking is the power relay trying to turn it on but there is an internal fault forcing it to shutdown. You either have a power supply problem, horizontal output transistor (HOT) is shorted or a bad flyback transformer. In any case it can most likely be repaired by a qualified technitian. If it is the flyback it may be expensive.

Hitachi 32 No Picture or sound


if you are hearing a click and electrical statics when you try to turn it ON, the flyback of the tv is busted there are alot of reasons for that problem lighting is one so dont leave the cable screwed in if ever youre going out for a long time. you can have it replaced by a technician ( flyback). but it would cost you. and im not sure if you can find an orginal flyback considering its 10years old. there are replacement flybacks but quality would not be as good as the original one.
