After opening the set I went straight to check on the safety components:

I found the surge limiter Resistor (dropper) open circuit but the fuse ok.

I replaced the dropper and powered on but it blow again instantly, I wish I had used the series bulb but it was too late.

I replaced the dropper again and used the series bulb and I notice d the bulb was lighting with lots of brightness indicating a heavy short. I measured the voltage across the man capacitor and found around 65 volts.

14 Inch China Television picture height low

I got a phone call from a client who wanted his television checked, I visited the place and was shown the television and when switched on I noted the picture was only present from the center of the screen to the bottom and also some retrace lines at the bottom.
