HDMI problem I have a composite cable set connected to my Comcast HD tuner and recently installed a HDMI to the same Comcast box. There is a slight improvement in picture and sound using the HDMI. My problem is that when I change channels and go from a NON-HD station to a HD station I don't get picture. This is ONLY when I use the HDMI cable. I changed to the other HD input and get the same results. When using the Composite cable I don't experience this problem. Also, if I cycle the power off/on the TV I get my picture at 1080i like I should. Any suggestions?
I have the same issue with my Sony Bravia. I have a SA 8300 HD Cable box and run the HDMI signal through my YAMAHA receiver. Switching between HD and analog channels generally causes the picture to black out (or snow out). Occasionally, I get flickering of both picture and sound (like the signal is being clipped) and I have to shut everything down and start it back up and then it works fine.

I also have the same problem with my Bravia when I use the HDMI, but not with component. The Comcast and Firedog guys thought I was crazy until they saw it for themselves. They were not able to fix it.I also have the same problem with my Bravia when I use the HDMI, but not with component.

HD channels are fine with component inputs but digital stations are terrible, compared to old Motorola box. What's the problem?HD channels are fine with component inputs but digital stations are terrible, compared to old Motorola box. What's the problem?

The Norcent PM-4201 plasma doesn't have a TV tuner. It's an ED-ready monitor. You'll need to connect it to a set-top box. This could be a OTA tuner in a computer, DVR OTA tuner, an ATSC converter boxes or a cable/satellite box. According to the specifications here, https://www.cnet.com/products/norcent-pm-4201/specs/ , the PM-4201 does not have any HDMI ports. You'll need a set-top box with composite or component video outputs. With a computer, you can use a DVI output (or HDMI to DVI). Note: the HDMI to DVI connection will not carry audio to the set.
Jan 3, 2012 - I can switch one of them from one HDMI input to the other HDMI ... The YPbPr option might be set at 720p, and you can change that to 1080i.
Oct 20, 2012 - Change it: Your Comcast/Motorola HD Cable Box may be outputting ...they set it to output a 720p signal via the HDMI out to my 1080p-capable ...
there isn't much point in connecting an hd converter the toshiba cx32g60. the tv can only support an sd signal (composite video or ntsc analog). however, many hd set-top boxes (dvd players, cable and satellite) have composite outputs. these can be connected to your tv. blu-ray videos can't be watched with this tv. (the hdcp (high definition copy protection) can't be sent through most converters.)

(if you tried an hdmi to component video converter followed by a component to composite video converter, the signal may degrade excessively.)
is your cable or sat in HD(720p, 1080i, 1080p) over the air broadcast in the usa is in digital so it should start at the highest res available in your area
next are you using HDMI or composite for your cable or sat going into your tv if not your not going to get higher than 420p because A/V and S-video do NOT support HD
check your cable/sat box is it HD(high def) or SD(standard def) if SD going through cattv/attn in your only going to get 420p
now for changing the resolution its automatic it goes to the highest setting on its own
you can control the resolution through your cable/sat box, blue ray/hddvd player and other HD devices connected to the tv through the options menus of those devices BUT only when connected through
HDMI(supports 720p, 1080i, 1080p) composite(supports 420p, 420i, 720p) A/v and S-video(supports 420p) cat tv/attn in(supports 420p, 720p, 1080i, 1080p) only supports what the tuner will do
Your dvd recorder only has rca, red white yellow inputs it wont allow you to record in HD, although you can play your comcast box any hd, regular digital through and record. Hook up the comcast box if HD through preferably HDMI if not get one from comcast. The HD box is the only box that allow HDMI, component and regular RCA and some RF out. This way you can play HD to your set but also record through RCA or RF again will not allow for HD record unless its TiVo. Hope this helps
Use an RCA audio/video cable for this set up (Yellow/Red/White).
Connect from the Video out (Yellow) connection on the back of the cable box to the Video in on the back of the DVR.
Connect the audio (Red/White) cables from audio out connection on the back of the cable box to the "Audio in" on the back of the DVR.
This should still get you a decent picture but not a true HD picture for your recordings.
When you set the timer to record set it to record either E1 or E2 depending on which input you connected the cable box to and ensure that the cable box is tuned to the channel you wish to record.
*** NOTE: If you keep the HDMI cable connected as you have for the cable box and watch normal TV through the HDMI input on the TV you will get HD programming for your general viewing but still have the option to record with the DVR at a lower quality. ***
If you want CC all of the time, this works well. But since you must power-off the cable box to change the setting, switching CC on and off is a real pain.
Your set-up is similar to mine (Sharp Aquos 46" and Comcast DVR). I have the composite output from the cable box going to a DVD-recorder and on to the TV. Whenever I need CC (usually to catch some mumbled dialog), I just rewind the DVR, and switch the TV input to the composite input. Then I switch back to HDMI to continue watching in HD.
1) Connect the Tivo using the coax output of the cable box into the cable input of the Tivo
2) Exchange cable boxes with your cable provider for one with composite output jacks. It may require you to use a Motorola box that isn't High def depending on what your provider has. I know Comcast has a Motorola HD tuner that has composite outputs as well as component.
3) Upgrade to a Series 3 Tivo. Those units are designed for High Def. Use HDMI cable hookup.
Connect the HDMI outputs on your various components to the HDMI inputs
on your receiver. Connect the HDMI output on the receiver to the input
on your TV. HDMI incorporates digital audio, so no need to buy optical
audio cables. If your receiver does not have HDMI inputs for all your
components, you will need to make a choice. HDMI = Best, component
video + optical audio = second best, S-video+ optical audio = third
best
your model is "tuner free" that means it does not have the RF screw in connector. Buy one that has a tuner, preferably both ATSC(USA digital) and NTSC(USA analog)
