Is There A Quick Fix For A Output Transistor Problem??,,,Or A Short??


If the output transistor is shorted you will need to replace the transistor. which doesnt cost much for the transistor, as long as you can install it yourself.

Blinking green light on a projection wide screen tv sill not turn on even with a system reset function any ideas?


A couple of things:
1) Power supply issues - most costly fix.
2) Horizontal Output Transistor went out 'HOT' - not a bad or costly repair/fix.
3) Flyback 'which supplies the 3 crt's' their High voltage.
Semi expensive repair/fix.
I would call and contact a few TV repair Service shops in town or your area and see if they can give you an estimate of repair.
Blessing,

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.

I have a Mitsubishi CS-3125R that displays a horizontal line with sound. I suspect the horizontal transistor is out and cannot find one. Any ideas?


You are misleading yourself. When you have a horizontal line across the screen it means that the vertical circuit is not working. You see, the vertical circuit moves the beam up and down which is not happening. The horizontal circuit moves the beam left and right and it is working. Your set probably needs a new vertical output IC and some electrolytic capacitors that work with it. The caps dry up with time and harm the output IC.

TV is beeping from the back.


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

Flyback transformer and horizontal output transistor change out


There is a little loose sleeve at the transformer. It can be pulled out, but it is best to squeeze the sides through hole on each side of the terminal to remove the sleeve. The wire just comes out with a small pull afetr the sleeve is removed. Good luck.

First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner.Feel free to ask and post whatever the result of your troubleshooting..


Hope this may help;

TV - worth fixing or pitch?


Horizontal output and regulator transistor often short out on this model causing a dead condition. Also the resistor right next to the regulators goes open as well. Electronix.com has a sony repair kit to fix the power supply. You just have to check the numbers on your Horizontal output transistor to make sure you get the right kit for your model.
