How do I connect my PS3 to my sanyo dp50747 in hdmi? I have everything hooked up correctly, but its not coming up on the TV. What do I do?????


If you see a no signal message, then it means that the signal output format of the PS3 does not match . It happens if you have previous used it on another tv and now connected it to a different tv. To resolve this, turn off the PS3 . Press and hold the power button on the PS3 till you hear three BEEPS. The PS3 should automatically detect the tv's resolution and the initial setup screen should appear. After that you should just follow on-screen instructions to set it up.

I have a 2002 Mitsubishi Medallion TV. The only input for HD is DTV (no DVI or HDMI inputs). Is there a converter box from HDMI to DTV that will allow for 1080i resolution?


From looking at the back panel of the TV, the DTV input can be configured as a component video. The M-Link/DVI-HD port is also a DVI with HDCP port and maximum signal handled is 1080i. The M-Link should work with an HDMI to DVI cable or adapter. For this to work, the source must not be a computer or another device using the default computer video output (computers give RGB output). The DTV port would need an HDMI to Component video converter. See this page for some examples: http://www.hdtvsupply.com/hdtocoad.html . The first one in the list (for Netflix and Boxee among others) will give 1080i out if the source is set correctly.

Most DVI-HDMI cables are single link. I've seen some examples where DVI-I (single link) and DVI-D (dual link) cables are not interchangeable. If you have video problems, check your cable. An HDMI to DVI adapters will let you run an HDMI cable up to the TV and then converter at the TV as a separate connection.

I hope this helps.

I would suggest to leave your directtv hd/dvr box connected the way It is.
The HD Colorstream 1input on your TV should work just fine.
This TV does not have an HDMI input but you can buy an adapter and connect to DVI/HDCP IN and that might be able to get 1080i video resolution on your TV.

HDTV goes blank when connected to Fios HD-DVR or Fios DTV recvr.


If you can first connect the Fios box via component and that will rectify the issue and still allow HD. HDMI is funny, if there is anykind of communication issues between the TV or the Fios box you see what happens. You might also call Samsung to see if there is ANY firmware/software updated for your TV specifically to fix such an issue with the Fios/Mortorola connection. If there isn't then the issue is the cable box since the TV works ok on HDMI with other devices.

DVI/HDMI Cable lost my pic and sound


Try disconnecting the hdmI cable and the dvr box.
Connect the cable directly to the cable input.
Sometimes the dvr boxes will cause this problem
after you connect the hdmi cable.

Connecting HD cable box to DVR too HDTV


When I hooked up my HD cable box using an HDMI cable, I had to go into the cable screen menus and select HDMI output. You may have to do something similar when using an S-video cable. Your DVD recorder doesn't seem to have an HDMI input, so you'll have to use the S-video or (worst case) composite video (red, white, yellow cords). Your cable box may also be scrambling the signal so that you can't record. That may be why you can record by bypassing the cable box.
