Check eBay "sony DAV-S300" check the 'include description' box. Several there.

You're not likely to find a non-boxed-set control center amp that can safely drive 3-ohm speakers like yours.

HTIB's aren't meant to mix and match with anything. Proprietary speaker connections instead of stripped bare wire are a tip-off.

If you really like the speakers you could troll the auction sites for a new central unit.

It could be down to the Region of the Player or the Laser is Failing. As it doesn't play CDs then I suspect the the Laser is Failing (almost failed if it plays a cleaner but not CDs).

Have you looked at page 57 of the manual?

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

The first two links you've probalbly seen before, they show conncections and connectors. I looked at pictures of your system and it would appear that the only input for video and audio is RCA. I think it has s-video for video only(s-video slightly better). The third link is the only way I can see to get what you are asking. It is an HDMI to RCA adaptor. You would use an HDMI cable out from your set top box to the adaptor then, RCA cables to your DAV-S300. It's the only way I can see. Hope this helps.

Please check the connections of your system and the speakers..!!

One source or many? Could be the source.

Make sure you have the correct input selected and MUTING is not on.

If the product is protecting itself disconnect all but one front speaker and see how that works out. If it starts working you need to isolate which one is/was the problem.

You .need a 5.1 reciever. Run the sub and speakers to the reciever run the reciver to your cable or tv

How does the sub connect to the receiver/amp? If it is a simple RCA phono connection, you can squeeze the outer tangs a little to make it fit tighetr. That will usually solve it.

A stereo 2 phono lead input from a sky box will have dolby pro logic surround info on it (when its a surround programme of course)

The Sony should then process this and give sound on the centre and rears too.

The DAVS300 does'nt have an optic/coax digital input so you can't have dolby digital from an external source- only from its own DVD player
