Anyone know anything about Television technical stuff?

[muzzer79]

I've got a Sony flat screen rear projection TV at home. It's about 4 years old.

It works fine apart from one problem.

We'll be sitting watching a program, and the screen will suddenly start shaking and going all juddery - like a wire has come loose or something so I'm only getting part signal. The channel number (AV1) will also come up in the corner of the screen. This only seems to happen when I'm on SKY. DVD player and Terrestrial would appear to be fine (although I hardly use those in comparison)

Most weirdly of all, if I go over to the TV and give it a firmish bang on the top, or a shake, it sorts itself out...

Anyone know what this could be? I've fiddled with the SCART lead at the back which seems OK and there's nothing loose anywhere that I can see. Whilst it wasn't too much hassle doing impressions of The Fonz from Happy Days to begin with it's driving me nuts getting up two or three times a night to wallop the TV now!

It sounds like the TV is momentarily losing the signal from your source.

How many devices have you got plugged into the TV. If more than one, do you get the same symptoms from any of these devices (eg. DVD player)?

I know you say the SCART lead is OK, but your description is symptomatic of a SCART connector not quite engaging (could be either end of the lead). Have tried a different SCART lead ? Perhaps try a higher quality one if the lead you are using is a cheapie..

Edit - just read your post again. So the problem occurs with the Sky box only, so its not likely to be the TV. I reckon its the lead. Try swapping the Sky and DVD SCARTs and seeing what happens..

If any TV experts turn up (I know there's a couple on here, but I can't recall user names) - anyone know about those SCART --> RF modulators so I can buzz my signals over my house using the pre-existing co-axial cable?

They work alright, they need composite scart rather than RGB (only the signal differs, not the connector, its just a setting on the STB) a normal RF feed is composite video anyway, these boxes just mux the audio onto it.

You have a dry joint or a loose connection.

Good man - I'll give it a bash

Cheers Plotloss, was just wondering whether it was worth getting a expensive vs cheap one off eBay... cheap one it is!
