There is sound but no picture, the screen is black, what can I do about that? horiz output transistor is out,may have poor horiz drive as well and the flyback transformer could be bad
...on untill its off for a while. Examine horiz circuit with magnifier.....look for bad solder connection.............check power supply area and solder pins of horiz output
... 257805; TL 02 ( horiz output transistor) 2SC5148; and open connections on the printed circuit board at LL 04 and L14401 (coils) all of which can cause the horizontal output transistor to be shorted. ...
horiz output transistor w/OEM or better quality. I was curious if you had any more information about which components they are or what exactly they look like. I have a degree in electronics so I'm not
Does this mean time for a new TV? Probable bad flyback transformer or shorted cap in horiz circuit,horiz output xistor suspect,also...................have tech check orreplace set....................T
...output transister is o.k. and the flyback transformer is also o.k. Check regulator and large filters in PS. Capacitors. Install horiz driver kit #483531057673 and replace 47mf/25v cap in horiz driver ...
horiz. output transistor) as well as resoldering the hhorizontal driver transformer and the horiz. driver transistor. Hope this assist yout repair and makes a happy one. Thats what were here for! Good
