TECHNIKA DVR100 DVD/VCR

[yellowpinky]

Hello Group,
The DVD does not work, It will not open the drawer or play.
The video works ok. After changing several stressed caps in the power supply there is no improvement.
If the set is left on for several hours the DVD works ok.
I have tried freezer and a hairdryer but no change.
Has anyone a circuit or any cures.
Thanks Ian Harrison (Sound and Vision)
