Page 1 of Help With TV/Sat Box/DVD Player setup

I hope someone might be able to shed some light on a little (but annoying) problem I`ve been having with my TV/Sat Box/DVD setup recently.
The problem is - approx every 10min or so the TV "drops out" - loses the picture & sound with the screen going a grey blank. Then after a minute or 2 it comes back on OK.
However, this problem only occurs on terrestial TV. It doesn`t happen on satellite TV or when a dvd is playing
My TV is a Hitachi one with dual scart sockets. I have connected the Sat & DVD player via a press button 3-way scart connector.
I thought that this must be the problem - so I went to Argos today - and bought a new one. (I bought a Masterplug (£29.99) one with an automatic switch-through which doesn`t seem to work- unless everything else is switched off - so it`s not recommended - and I`ll probably take it back.)
However, the same problem is occurring with this unit as well.
The only other thing I can think of is a faulty scart lead?
Can anyone shed any light on this?

Everything screams out at me TV fault in the tuner section (analogue side of things) not SCART connectivity.

Yeah, if it is the terrestrial channels only it gets the signal from the coax cable so as Rassilon63 says, sounds like a tuner problem, not scart.

You could try unplugging everything from the scart sockets and see if it makes a difference but I doubt it will. That will eliminate your DVD and Sky box from the equation.

Thanks for this - but apologies!! - since I`ve just discovered that the TV is also "dropping out" & going into standby mode when connected to Satellite TV as well. The TV is a Hitachi 28" widescreen (C28W410SN) purchased from Argos approx 4 years ago. Any ideas as to what to check for. Any further advice would be appreciated. Thanx.

i dont know if this is much help to you but i bought an hitichi tv from powerhouse approximatley 4 to 5 years ago and i had the same problem. i`d be just watching a satalite programe or dvd and it would just go off i could usually get it back on withn a few mins with the remote or by switching it off and on again. and for the longest while i thought it was the remote untill one day it went off and did not come back on again.
£90.00 and a new power suply later it was all working fine and its never switched off again since..
