sony slv-e700 supply module

[willy11]

Hello,

I have a problem with the supply module SR522 1-413-897-11
Have some one a idea what is the reason ?

The voltage 300V in and the voltage out of this module 13.8 V and 5.9V ara not stable.
The vcr and display is on - off - on automaticly
If a changed the module (from a other vcr) the vcr works good

Thanks
