Title: Kortek Chassis
Post by: hammad on November 21, 2006, 01:26:41 pm: Hello,
I have a request....if anyone can please mark out all the electrolytic capacitors using ms paint in this kortek chassis for me i will be very grateful to them.

Post by: Rickn on November 22, 2006, 07:41:45 pm: Yes, they are both right.

Why do you ask???

I assume the monitor is dead??

Based on the picture, the electolytic by the flyback has a "Bulged Top".

Just inb case the flyback is the transformer on the right with a red high voltage lead that goes to the picture tube.

If this is so, then it likely dried up, changed value and took ot other components- look for burnt resistors.

Unfortenately the list could go on....

Good luck

You've got the chassis...you tell us!

Post by: grantspain on November 23, 2006, 03:52:51 am: i am helping hammad resolve a few issues with this monitor,he has jail bars which is a cap fault on the ht smoothing circuit and i have told him to change all the caps,the reason he is asking about this particular cap is that someone has attached a resistor to the positive leg of the cap and i don't know why-it is possible its a factory mod but it seems more likely that its a previous repair and its possible the last repair tech did not have the correct value cap so hence he is double checking the value
i worked on lots of these chassis in the distant past and do not remember any resistors connected to the solder side,if anyone has a schem for this chassis maybe they could look up that cap value

Post by: grantspain on November 23, 2006, 04:12:32 am: my feeling on this particular cap is to replace it with the value that is in there already and leave the resistor attached,change all the other caps and see what happens-what do you all think?
