My daughter's TVs have been working fine for the last 3 or 4 years but 2 or 3 months ago the picture started freezing & the sound distorts. It happens from about 5pm till about 11pm to varying degrees most nights. Outside of these hours picture & sound are fine.
The main TV in the lounge has Freeview and changing to an analogue the picture & sound are fine. There is a TV in each bedroom. There is a Wolsey WFAV 425 4-way splitter in the loft (although the gain was on minimum, I have turned it up a 1/4 and it's made no difference) powered by a Wolsey WPS 100/1 power supply unit in the main bedroom.
All the connection are fine and the light on the power supply is on.
Could the power supply have developed a fault? Or is there anything else I could check?
Any suggestions would be welcomed.
