SOURCE: blue screen with HDMI

Check the power supply modular cable connection that is by itself in the upper right corner.  On the one my son-in-law has the double yellow jumper wire that connects to this plug in two locations was loose (not properly inserted) in the modular connector and had worked it way out.

SOURCE: TV does not always recognize the DVD player

that's a firmware problem where your tv's firmware does not handshake with your dvd's firmware. This could be from your dvd's software being to old for your tv to understand it. HDMI (TDMS Technology) still has Alot of catching up too do with 3rd generation tv's. Alot of HDMI devices still have the first gen software loaded into them. So a tv after 2005 won't work with HDMI from 2003 (1st gen). Most tv's made after 2007 have software that's "backward compatible" so they will work with first gen HDMI.

How does your tv perform outside this problem???

SOURCE: Westinghouse TV no stereo

Hi my name is Roety,
I can help you with your issue ,
Why don't you simply run the cable box and DVD stereo outputs direct to the receiver. Thats what most people do. TVs do not passthrough stereo signal very well do to DHCP compliance requirements .

Intermittant Audio with Yamaha RX-V465 only from cable box


I have the same receiver... You can try pressing the Option button and choosing Signal Info to see what audio signal the receiver sees and if that changes over time. Maybe the cable box is not outputting according to specifications... TV can live with that, but receiver maybe can't.
You can also try to connect the cable box via SPDIF cable (optical or coax) to see if it helps or not.

HDMi ( no signal, not supported) doesn't work with Dmr-Ez47v


Any HDMI cable manufactured in the last couple of years should all be HDMI 1.1 compliant, your problem is most likely the logic board in the TV itself or the HDMI connector on the logic board has a bad connection..

Have you tried hooking-up a standard DB15 VGA cable to the AKAI TV and your laptop?

If this works your problem is in the TV and will most likely have to be repaired to receive the HDMI signal since your Panasonic DVR and your laptop are not recognized by the HDMI input on the TV.

Good luck!

Progressive scan


Approach 1: Try unplugging the DVD player from the wall for an hour, then plug it back in. It may or may not reset to the factory default settings, which might put it back to "interlaced" output.

Approach 2: When a DVD player is switched to progressive scan, it uses outputs different from the coax cable "TV out" and the COMPOSITE outputs (often yellow, white and red RCA jacks. If you have the proper cables, you can connect them to both the DVD player and the TV, then cycle through the AKAI TV's "source" settings to switch the TV to the new cable input location.

For example, if the DVD player has "component" outputs (marked Y, Pb, and Pr) hook up RCA plug cables between those jacks and the AKAI TV's Y, Pb, and Pr jacks. Connect the Y to Y, the Pb to Pb, and the Pr to Pr, of course. The LCT3285TA has two sets of these jacks. Either will do, but note if you use YPbPr1 or YPbPr2. Once this is done, push the source button on the side of the TV (or on the TV's original remote) until it shows YPbPr1 or (...2 if that's what you connected). If the DVD player is on, you should now see the DVD menu or the picture from the DVD. Now you can use the DVD remote to switch back from progressive to interlaced video. The picture may go blank at this step.

Now push the TV's source button again until you see "3" or whatever channel you had been using in the upper left of the TV screen. You should see the DVD output picture (menu) again. Back to normal.

If your DVD player doesn't have YPbPr connections, it may have a HDMI or DVI jack.
The AKAI TV also has a HDMI input, you *could* get and HDMI cable (or DVI to HDMI cable if the DVD player doesn't have HDMI), hook it up, then cycle through the TV's source inputs until you see the HDMI in the upper left... in the manner I've just described.

Final Note: The progressive scan output of your DVD will actually give you a much better picture on your AKAI TV than its interlaced output. To take advantage of that, you'll have to hook up YPbPr or HDMI cables between player and TV and switch sources when you want to watch DVDs instead of TV programs. You may need additional cables to send the stereo audio output from the player to the TV for the progressive source hookup.

Compatibility Issue with HDMI Switch?


anytime your talking about a switch your talking about a temporary connection. The issue with using a switch is that for HDMI you want best quality and you will not get that using a temporary connection. The unit may be recognizing a weaker signal and turning the port off. However since the output on that particular unit is 1080i you should be fine using composite, just get a nicer monster set.
