Question about Sony FD Trinitron WEGA KV-27FS100 27" TV

KV27TS29 27" Sony Trinitron 1993

While watching tv we heard a loud zap, then it shutdown. unplugged tv and noticed the plug prongs were burt. No lightning or power surge as other equipment was on and remained working. Curious of the cost to fix, as I have a friend with 1994 model with same issue. I have had lots of luck with minor solder repairs in the past with receivers so I have opened up and found power throughout the power supply, and have not seen any leaking capacitors or noticeable damage to the board. It is an older tv, but everthing new I look at is more than I can spend.

If you state that the contacts of the Mains Plug were 'burnt', I suggest that you once clean them with Emery Paper and try again. Loose contact in the Mains causes the 'burning', and the Plug contacts become carbonised. Could be other reasons also, but just try this first.

Screen blank

Sounds like a cap or fuse has blown in the set, you will need to take the back cover of and have a look, check on the power board for any blown caps, you will notice them straight away if one has poped, also check any fuses that may have blown they will also need to be replaced.

Cannot see TV through digital box on my sony trinitron

If there is no audio as well then this suggest that the digital box is at fault. The fact that you can watch DVD's proves this fact. Unplug the digital box for 2 minutes and then re-try. Good luck.

I think you had an arc in the high voltage circuit which zapped the blue drive circuit to the picture tube. This could have been caused by the high temperatures the your set was subjected to. Stargazer
