SOURCE: PS3 been working fine over

TV Connectivity
The issue of connectivity between the PS3 and the display is very complex and depends on the type of TV (Analog, Digital or HD Ready), the maker of TV (until recently, only Toshiba TVs have component AV connections as standard in Europe, most other Euro TV sets use SCART which can not carry an HD signal) and specification of TV (the very latest HD Ready TV sets have wider connectivity options than earlier HD "capable" TVs from the same manufacturer which may have lacked HDMI), and finally the configuration of the PS3 model purchased.

It sounds like the HDMI port on the back of your Marantz is damaged. if you know for sure that the HDMI port works on another tv still you might just use component connection because the visible difference between component and HDMI is not very recognizable.

Grey screen means the T-CON board is not getting 12vdc feeding it, check the fuse and voltage on the T-CON board.

You need to check the DC output voltages on the power supply DC output connectors first.

Why would tv sound work fine but while using roku 2 the sound suddenly stopped working?


If the picture is OK then check your sound cables, red and white if analog, or swap out the HDMI cable with one that you know works.
Also, on the SETTINGS screen make sure your audio is set to stereo not surround sound.

New toshiba lcd has sound, is getting all cable


Hi,
What kind of video connections are you using to hook up the cable and the dvd player? Also does the menu of the tv come up normally? Once I have more information I can assist you further. Worst case scenario you will end up needing to return it for a replacement where you bought it from but lets do a little troubleshooting first.
Thank you,
Lee

I have a Toshiba 37" LCD TV. It's either a 37AV50U or 500U. I watched it for awhile last night with no issue and today when I tried powering it on, it would not respond. The remote won't work either...


You most likely have bad capacitors in the power supply. It's not an expensive repair so I recommend taking it into a service center for a complete diagnostic evaluation.
