I meet a client who wanted her TV checked by a technician and after asking her a few questions about the nature of the problem, I realized I was not getting the real picture of how the screen was since she was talking of picture being washed being out.

So I requested her to send me the screen shot of the TV screen via whatsup and this is what I got.

Sony home theatre DVD receiver model HBD-DZ350 dead now repaired


My neighbour brought to me this DVD receiver to my shop for repair a few days ago.

I did my usual initial test by connecting it to the power outlet even before opening it.

I noted the machine was powering on briefly and then shutdown, with this I concluded that the machine is getting powered but shutting down due to overload somewhere within the system.

With this in mind now it is time to open up and find out where the problem is.

In this case substitute the main fuse (across the two pins of the main fuse holder with a series bulb.

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.

Usually whenever you see the screen is not full vertically means there is some problem with the vertical circuit meaning it is not doing its work of opening the screen vertically.

Since the owner wanted the TV back urgently he decided to accompany me to my workshop and once on the bench I opened the set and went straight to the vertical circuit.

14 inch JCV Television dead now repaired.

I customer came to my shop and asked if I can check out his television with went dead yesterday while watching news.

He went back to his house and after ten minutes he was back with the said television.

I plugged the TV via my series bulb to confirm what he said and indeed the TV was dead.

Looking at the fuse I noticed it was not there, further checking I noticed the TV was from another technician and after repairing decided to use a just wire instead of actual fuse.
