Question about Toshiba 42HP83 42 in. HD-Ready Plasma Television

1 Answer

When switching from any input to HDMI I get a split screen

When ever I switch from colorstream or ant. to HDMI I get a split screen. The top 2 thirds is split in the middle with the main figure on both sides of the TV. The bottom third, all of the colors are drawn down and it kind of looks like a bar code. The Tech came out and changed the component board and the HDMI board and that didn't solve the problem. Now they are telling me that it is a normal function with that TV. I find that hard to believe because it did not do it before. Is this a normal function on a 4000.00 dollar TV? Thank you for your help Dan

    Also the picture will black out sometimes when using HDMI. You never know when that will happen.
    Tech also nicked the screen when he laid the TV flat on the floor. I think that he laid it down on a screw had the back off. Can that be fixed?

    My TV is a Toshiba 42HD84 Plasma

    According to Toshiba there are no software upgrades for this TV. The picture also blacks out and comes back on split. This not only happens with the cable box it also blacked out when I had the HDMI hooked up to my Direct TV Box as well.
    They tell me that in order for it to work I have to turn on my TV first then the cable box. That helps but you should not have to turn off the cable box every time that you go from one component to HDMI. That would be like turning off your car to shift gears. I talked to Toshiba and they told me that this is not a normal function.

    Yes the cable box works fine when hooked up to colorstream. So did my Direct TV box.

Are you tring the same sorce for the component (colorstream) as with the HDMI? What is the resolution you are using? The possibility is that the sorce could be the issue or the TV might need a software upgrade to fix any HDMI issues.

Sounds like a loose connection. Make sure your cables are secure. Try switching your INPUT selection on the remote to something else, for example, if you're watching cable, switch to HDMI, or A/V or something.

You can also try, if the input w/ the issues is HDMI, either swapping your cable for a new one, or swapping which HDMI input it's plugged into.

Good luck.

Page 18 of the manual, you shouldn't need to do steps 2 or 3.

1.Connect the HDMI or DVI to HDMI connection cable from the output of the HDTV set top box or DVD player to the HDMI input as shown on the AVC Center below.
2.With DVI output, connect the cable from the AUDIO OUT R of the HDTV set top box or DVD player to the INPUT (AUDIO/R) jack.
3.With DVI output, connect the cable from the AUDIO OUT L of the HDTV set top box or DVD player to the INPUT (AUDIO/L) jack.
4.Press the INPUTS button, then select INPUTS 1 or 2 to view the program from the HDTV set top box or DVD player. The VIDEO OSD label disappears automatically after approximately four seconds.
5.Select ANT A or B from the INPUTS menu to return to the previous channel.
NOTES:1. Completely insert the connection cord plugs when connecting to rear panel jacks. The picture and sound that is played back will be abnormal if the connection is loose.
2. The HDMI input on INPUT 1 or 2 contains the copy protection system called High-bandwidth Digital Content Protection (HDCP). HDCP is a cryptographic system that encrypts video signals when using HDMI connections to prevent ******* copying of video contents.
3.HDMI is not a "NETWORK" technology. It establishes a one-way point-to-point connection for delivery of uncompressed video to a display.
4.The connected digital output device controls the HDMI interface so proper set-up of device user settings determines final video appearance.

How do you connect a VCR and a Cable Box to a DAEWOO TV that only has one Cable (ANT) connectionn on the back?

The antenna is normally connect to the VCR, which should have ant. IN, and OUT which goes to the TV. If the TV has HDMI input you would connect the cable box that way. You can also get a TV signal switch box, 2 in, 1 out, with a remote to switch it with.

How do I connect a Cable box and Blueray player if my TV only has one HDMI connection on the TV?

Not sure how good they work but I have seen plug in adapters which split a single HDMI input to a two unit input. Like we used on older computers to gain additional USB ports.

Split screen question

To get a split screen working on this set, you will need to do the following steps.

1. Put a splitter on the incoming cable.
2. One side will go to the digital cable box and one to the tuner on the television. (Ant A)
3. Hook the digital cable box using the video out from the box to Input 1 on the set.
That should do it now select your digital cable on Input 1, and then select the split screen source as Antenna A. You may have to switch sources to select a different input.
