I purchased my Dynex 26(?) late june, and fine until yesterday. watching tv, which is connected to a time warner cable box. tv hums both cable and tv switch off. turn both back on, but now tv screen is very dark and cuts off after a few minutes

Change you hdmi connector.

If the cable box has audio and video outputs on it then use RCA type cables to connect the outputs of the cable box into the video and audio IN of the back of the VCR. Then select L1 on the VCR. If your TV has video and audio input connectors connect another set of cables form the VCR OUT to the IN puts of the TV, then select the AV inputs on the TV. If your TV doesn't have video and audio inputs, then use a coax cable from the RF/Antenna OUT of the VCR and connect it to the antenna jack on the TV. Now select 3or4 on the VCR to whatever works for your location and tune the TV to that same channel. That's it ...you now can watch and record the channel you're watching. You will have to have the VCR powered up all the time to watch TV

Have you tried using component cables instead. One of my Time Warner cable boxes did the same thing using HDMI.

time warner has only one code and it is 400

split your input cable line and connect one end to your digital input and the other to your
analog or air input.

10463 try using this code

Connect cable on combo player cable in post to time warner cable box cable out post. and connect the combo player to TV with audio and video patch cords.

try connecting the box to a different input
also try connecting another device (like a VCR) in place of the box to see if the problem exists without the cable box

When you use the Time Warner Digital box, you're using the tuner inside that box rather than the tuner inside your TV to select a channel. Picture in picture TV's have two tuner's inside so you can view two channels, but they can only tune the analog channels from your cable company, and only if it's hooked up in a manner that will permit this to happen.

So you only have one digital tuner (the Time Warner Box) so you can only view one channel at a time even though your TV supports Picture in Picture.

It MAY be possible to have limited use of the PIP if you connect your TV in a different way. Your Time Warner box is most likely connected to your TV set with composite cables, those are the Yellow, Red, White cables. If you buy a coaxial cable splitter and split the cable before it goes into the Time Warner box you can then run a coax cable into both the Time Warner box and the coax input on your TV. This would allow you to tune the analog Time Warner channels with both of your TV's tuners. In my area I think the first 60 channels or so are still available in analog, but there is no way to watch any of the higher premium channels without the Time Warner box.

If you go through these steps and you select the coax input on your TV your PIP will work on the lower channels. It MAY be possible to tell your TV to display the input from the composite cables on one of the PIP screens and the input from the coax on the other, but I kind of doubt it.

I know this sounds complicated and if you're not familiar with the way all this works it is complicated. The reason lots of people won't respond to this kind of question on this site is because there is no easy fix and by trying to help I run the risk of getting a bad rating. I don't get paid for this, I just like trying to help, so if I have not explained this in a way that's helpful to you please ask some additional questions before you give me a bad rating. Thanks.
