TV is not recognizing the dvd player

SOURCE: HDMI Input Failed

I've been seeing alot of this out in the field. The cable is thick and heavy, after awhile the HDMI connectiion inside the set comes apart and breaks from the main board. In my opinion the only difference between Component jacks and HDMI inputs is the thought of reducing the amount of wire mass in the back of the unit. It's more pleasing to the eye. If it's under any kind of warranty, call a servicer. The main PCB will need to be replaced. If it's not under warranty, use component input cables, you'll get the same performance from your set and save a few bucks.

SOURCE: Audio, but No video when connecting DVD player to TV

Try checking the AV cable. Just interchange the Audio and Video cables, and if now you get video, and no audio, problem is faulty cables. Replace.

You need to bypass your A/V tuner for your video connections (if possible). Plug your video directly into the TV and audio into the tuner. This will also give you a cleaner signal/picture as it does not have to processed by your tuner BEFORE it goes to your tv. Think of it as cutting out the middle man. Your tuner is best left for powering your speaker and not controlling your video despite all of the available connections in the back of it.

I would also get rid of your VHS and cassette players as they are dead technology. Clean up your system and remove the clutter. This will lessen your chance of getting interference. Good luck!!

SOURCE: Toshiba 26AV502U (new) video dropout if VHS tapeis not perfect

Had problem checked by local outfit called "Circuit Pro"; their analysis was compatibility.
Actual answer was that the Toshiba required a better quality input from "any" VHS source.
I finally took a "less than perfect" VHS tape with me when I returned the Toshiba TV to the store and demonstrated the problem to one of the TV sales people. He played the VHS tape through a display VHS/DVD player to three different brands of TV. The picture was often "black screen" on a Toshiba, but was merely poor quality on the other two brands. I upgraded to a Sony KDL26M4000 from the Toshiba 26AV502U.

You are worrying needlessly. Just buy a head cleaner and run it through. It's just like the old VCRs. The heads get an accumulation on them in time, and it is certainly cheaper and easier to clean them than it is to replace the unit. Please rate this answer.
