Question about Sansui TVS2750 27"
When the tv is switched on, a black and whit pic appears for 10sec the the screen turns blue and white horizontal lines appear.
Note - sound is ok
SOURCE: Horizontal White Line
In your statement i found during switch on you get picture. Check whether in a few minute picture suddenly goes to the horizontal line or height reduces and then goes to line. If suddenly goes means change any zener diode in pumpup circuit. If it is not means LA 7840 ic getting imbalanced supply voltage i.e.,negative and positive voltage are not equal. Suppose only one vcc means supply resister getting high ohms and change the the supply resister.

Have you tried the a / v inputs?? If they work,might be a bad tuner.If they don't work,then your symptom is no video-no audio=
power supply problem? Check all voltages....T.

Check for short circuit on your Powersupply. If you can isolate it, much better. check the voltage regulator if it supplies power to the system. better still check the regulator itself.
