I have audio but no picture except a horizontal light across the middle of screen. Sylvania 32" tube type TV. Model SST4324


Sounds like your Output Transistor has blown. I would suggest you take to your nearest TV repair person. Will most likely cost between £30 to £50...
!.This is not a job you should carry out yourself. As you are dealing with High voltage, even when TV is turned off.!
Hope this helps

Sound, no picture, Red LED 4 flashes


Hello Thanshar, Hi, you TV has sound, but no picture. this could be several things, and let us add the red led flash. In my analysis, no picture means no high voltage is reaching the picture tube. this could be due to a bad Horizontal output transistor, and/or a bad flyback transformer. This bad transistor is causing an overload to the power supply section, causing the 4 led flash to blink. Now i want to know if you want to do this service or get professional help. if you decide to do this by yourself, this needs to be performed: the Horizontal output transistor must be checked for short, the horizontal flyback transformer needs to be tested, the deflection yoke also needs to be checked, especially to horizontal coil.

Pop sound frome tv could it be a fuse? now it dont come on.


The pop may be the Horizontal output transistor, shorted. And that is usually because you have or had an extremely dry or bad capacitor! It may be an expensive fix. Thanks for asking!

No picture


I disagree with given info, this tv has no horizontal output transistor because it is dlp tv.
3 red light blink means lamp cover is not placed back properly after lamp replacement/ lamp checking. Make sure lamp cover is fixed back in its place securely and tight.

TV is beeping from the back.


The horizontal output transistor is shorted and probably the flyback transformer is bad as well. Expensive to fix.

JVCAV-N2043TV,Horiontal Output Transistor burns out everytime if fix a new one


Hi There,

The Hor Output transistor is connected to the Line Output Transformer. This transfromer provides a lot of voltages around your TV set but includes the very high voltage to the Picture tube...

These transformers are specially tuned to resonate at a certain frequency,
The Hor output transistor needs to match this frequency....so if the wiring inside the transformer is shorted by "just a bit" the picture will be visible but the transistor is struggling to match the transformer impedance,from the mismatched tuning...so the transistor draws more current from the power supply.. runs hot then burns out...

Usually manufacturers provide a Trip circuit that detects that an overload on the power supply is occuring and cuts the power to the Line output stage ...this is usually detected by a clicking sound within the power supply its called hiccuping.

If some one has altered the correct setting on the power trip circuit then the next thing that happens is the Transistor goes Blooooey like in your case.....

So to save you a lot of money replacing the output transistor
please replace the output transfromer as well next time...

But please... please... re-check the power supply trip circuit to save you a lot more expense in the future....

Best Regards From YUBEUT
