will a monitor explode, or had explode in the history you have know of..when the screen is ticking fequently?

Question

where to check and how to fix it?
very much appreciate, thx..
please give comforting answers only please

Answer 1

I haven't heard of one exploding.

When they fry, there might be a little smoke and a zap.
There is over 10,000 volts under the cover of the monitor, so don't touch anything unless you have someone nearby that knows CPR. Even when the power cord is unplugged, there most likely will be 10,000 volts waiting to greet you.

So now that you are comfortable...

Please don't try to fix it yourself. Either have it looked at at a shop, get a new one, or live with it.

Answer 2

I am guessing that this is a CRT.


CRTs do not explode. If anything they implode. However part of the safety testing of a CRT is to drop a 1kg (2.2 lbs) steel ball 1m (3'6") onto the front of the glass. The back of the CRT is much more delicate, but you are protected by the monitor casing.

CRTs can tick, sometimes the image can go black or twitch when it doe this. This is called a flashover, and is an arc between the electrodes in the CRT. It should do no harm, at worst it may change the colours of the picture. Unfortunately there is no fix. This is usually a sharp snap or click.

Other reasons for ticking could be the S-cap relays switching with a resolution change. This is normal.
Or high voltage discharge from the high voltage lead. This happens with dirt and dust buildup on the lead and the build up of charge on the outside of the lead. It is not a problem. (Other than the annoyance) This is normally a softer single tick repeated every few seconds or minutes.

Edit:
To fix it take it to a TV repair shop. They will have to listen to it and open it up to determine the cause.

BTW, CRTs do not have 10,000 volts in them. That is way too low.

20,000 to 30,000 volts depending on the size of the CRT. If you do not know what you are doing don't mess with them.
