Vertical Hold circuit?

I have a Sansui Model number TVS2746C. Made a pop noise smell as if something went/smoked. It still powers up...but just a single horizontal line. I am thinking something with the vertical hold circuit. ??????
Thanks for your help.

The pop you heard was the vertical IC (LA78041) blowing up. You will most likely find two 30 zener diodes (located directly behind the vertical heat sink) shorted as well.

That is usaually a component in side the board called a capacitor that bursts due to high voltages passing thru it. so u will need a technician to replace it for you at a cost

MY 1993 CLUB CAR GOLF CART WILL NOT MOVE, I HEARD A LOUD POP WHEN I WENT FROM FORWARD TO REVERSE/ANY SUGGESTIONS?


check to see if there is a circuit breaker on the wire path from your batteries. Could have blown the motor but You would see some smoke more than likely, and smell it burning. What you described with the popping sounds like an electrical short where the wires just burned up but again you'd smell it and maybe see smoke. The switch may be bad also check it with a meter to see it its making contact and see if voltage is coming up to and exiting the switch.

Shorting out when you turn the dial on front ,was making funny noise the other day too


Please post a model number. What do you mean by 'shorting out'? Was there a pop, or spark, smoke, or burning smell? What was the funny noise? A hum, a clanking, a squeal? And what area of the machine did it come from? Does the machine agitate, spin, or fill? Thanks.

Check IC601, C603 for leakage, I601 and vertical pulse detector QN05

My dryer went "pop"


it could be your mains filter it is situated next to your motor if that has gone it wont work you can usually get one off another dryer doesnt have to be same make but it has to have same numbering on it but most are the same mate if this does work you might find burnt wiring at the inside front of your machine which leads to your door catch if that wiring is burnt out just replace wiring and it should work fine mate let me know what you find and ill try and suggest what you can do
