Question about Televison & Video
I don't watch this television too often, it was made in 2000. The other day I had to move some stuff and unplugged the TV, then plugged it back in to see if it would turn on. I got a picture for about 20 seconds then heard a pop and smelled something funning on the right hand side of the TV and immediately unplugged it. Any thoughts on what to look for I can repair basic electronics/circuits have a o-scope and a DVM etc. Just never worked on TVs this new, used to replacing tubes! =)
It would be the psu, you may be lucky and its just a few blown capacitors that need replacing, if you have not used it in a awhile and its been in standby, then you unplug it and plug back in, it can sometimes blow, as its not been used so components maybe weak, then turning it on has caused the voltage though and the weakness in the capacitors to blow.

Sorry mark that high pitched noise is an indication that the switching power supply has an overload on the outputs. It could be a shorted Horizontal output transformer or transistor or a combo of both. Also could be a shorted vertical driver or output device or could also be a simple cap opened up and is causing a really large current flow BUT if your not a tech i advise you not to tamper with or open the set as you will not "see' a problem or "look" at the open set and find anything wrong! these sets are not user serviceable and can cause you great harm.. So please if the set is this old its probably not worth investing any cash into the repair unless of course it has personal meaning to ya. its up to you to decide Good Luck

If you hear a ticking and or buzzing sound as it is trying to start up then most likely the replacement lamp is bad. Take it out and reseat it one more time to see what happens. The noise you hear is the ballast attempting to fire the lamp up.

I have a 37"Samsung LCD and having just spoken to the Sky engineer (also a friend) he says it is a national problem between Sky+ and Samsung. I have the same problem when on playback but not on real time? If you had your box changed to an Amstrad what sort did you have the problem with?
