Since 2010 I have a Philips TV 37pfl 8605h. For digital TV I installed Ziggo Smart card Ir.deto.
For Net TV via Local net I installed USB PTA 01 adapter.
Incidentally there are short interuptions in sound and blocks in the picture. I got the advise to remove
the USB. No interruptions any more. Repaced USB a day later; no interruptions. Now again incidentally
interruptions. Mainly just after activating the TV. Is this a warming up problem? Please advise me.
