If you see a brief spark at the outlet when plugging in the power cord, this may be absolutely normal. It is the surge that happens when a modern switching supply is plugged in and that big capacitor charges up. If no fuses blow, and the spark occurs every time it is very likely normal. Some poorly designed supplies give a real arc-weld when plugged in, most just crackle a bit.
To the original problem, most newer sets have a small amount of power that is supplied to a microprocessor control board. If this small supply is out for some reason the set won't turn on.

Hi there!

Where you saw the Arcing, check closer to see wether the components are not loose on the board. You may only have to resolder the joints and problem solved. If the arcing takes place towards the tube, then you have a more serious fault. Thus involving High Tension, so I would not advise trying to repair that area if you are not familiar with TV repairs. Please unplug set before commencing any work. Regards and good luck, JUS004

My 32' Sony trinitron went dead like I switched it off. (I didn't). Now it won't come back on. No lights, no hum, nothing. Model kv-32th77 Made in August 1994


No power is coming to TVPlease check the power cord, the plug and the socket. See if it is OK by connecting to any other device. If this is OK then the safety fuse inside the TV is blown. You have to get it replaced.

Daewoo TV Dead


STARTING: fuse, swelled capacitors, voltage reading on the output of the power supply board. In that order. BE CAREFUL the power supply board is the one that plugs in the wall and has 120 volts on it. The output should only be 5 and 12 volts etc. If you have nothing there, that's a good thing, the rest of the TV is probably good.

WARNING: This applies only to a modern, flat TV. If it's a older CRT type, they have up to 50,000 volts in them and will KILL YOU.

Tv has no power, can't find reason.


they have little relays in them, kinda rectangle and tall on the board, you can peel the thin plastic case off the sides and manipulate the switch to narrow it down as to which one is bad.

The power supply may have failed components. It is also possible that there is a failure in the scan amplifiers and in the high voltage sections that caused the power supply to fail. There are a number of scenarios that can cause this type of failure.

The set will require proper troubleshooting to service it. These types of failures will usually not show anything visually.

The first thing is to check to see if the fuse is blown,if so replace with a 5 amp fuse,fuse is located near were the power cord connects to the board,make sure set is disconnected from power.
