Question about Sansui TVS2750 27"

1 Answer

Sansui 27" Have a problem with 27" sansui tv, after being on for a period of time picture starts to pull in from right side, then tv shuts off, suspect a B+ or High voltage problem, or possibly a capacitor, not sure, don't have schematic, wondering if this is a common generic problem with a simple solution.

    Hi
    Well, after careful examination, I see no defective solder connections or a burned loose resistor, also after use of contact coolant spray on certain components, has also turned up nothing, I wonder could the High Voltage Transformer itself be failing and causing the protection ckt to shut down the set? I notice a horizontal tearing of the picture as the deflection is pulling in from the right side too, just before the set shuts down, does this give you any other ideas?

I think you're on the right track. It sounds like the problem is in the horizontal deflection circuit or pincushion circuit.Maybe a bad solder connection or a resistor burned loose from the circuit board. Stargazer

The picture has gone out on my 27 inch Color Sansui. The sound is still working but no picture. This has been going on for some time. The problem started out blacking out for about 10 min., then the pic...

there could be other causes but the first thing that shoud be checked first is the existence of dry joints that develop overtime between souldered joints due to contaraction end expansion forces caused by the heat as you leave you tv on for hours and off again. if you scruitnize the souldered areas you can see then and just resoulder the areas.

I have a 27 inch sansui television. It is about 5 years old and white lines have started to appear at the top of the screen. They are kind of annoying. Does anyone know what that is.

If your TV has a picture tube rather than an LCD display, you have a problem with the vertical circuit
(the circuit that "paints" the picture from top to bottom). Usually a capacitor in this circuit will open up causing this type of problem.

My tv shuts off after only two minutes

try using a master reset to fix this.
Sometimes after being used for awhile electronics tend to malfunction.
press and hold these buttons in this order....
power / volume up / channel down.
The tv should shut off after doing this.
Turn it back on manually.
This will reset the TVs internal memory chip.
I dont guarentee this as a permanent fix....but it worked for me.Good luck
