The "no sound" part worries me, but the board may have bad solder connections in the vertical section or simply the vertical deflection IC is bad. No sound may be the result of not being able to know you are on a correct channel. Usually when this happens, the bad solder connections are very obvious. I don't have a service manual so I can't direct you. If you do choose to inspect the board, unplug the unit first and note that CRT TV's commonly hold charges before you go touching around inside, if that worries you then don't do it. Most vertical IC's are straight in-line pinned, inexpensive, and when they go may take a load resistor with them so look for burnt/scorched resistors, possibly even a cap that's blown it's stuffings out. You should have or know the basic theory of TV process or you are just hoping for a magic fix and shooting in the dark.

sounds like vertical retrace lines. The horizontal line fault called so. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor.

Hi My toshiba CX36H60 has a problem -- no picture but sound is good. what could be the issue and how to rectify it. Please suggest.


As sound output is ok, main board is correct with respect to sound output, video IF and ther stages. The fault lies on the horizontal output section. It may be LOT fault. Check it further for horizontal oscillator stage, and horizontal output stage. Check the collector voltage at the horizontal driver transistor. If you have a frequency meter, check the frequency of that point. It should be somewhere near 15625Hz. If the frequency there is Ok, then proceed to horizontal output stage. Check the horizontal output transistor. If it seems to be faulty, replace it with similar type and number. If the replaced horizontal output transistor heats abnormally within seconds after swich on the set, surely LOT has troubel. Replace it also with same model mumber and type.
