Remote not pairing

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience. http://electro-medical.blogspot.com/

The word ''no sync detected' means that there is no video connection between the cable box and the TV set. Isolate the source of trouble by connecting to the TV a prevoius video source that worked properly e.g DVD player. You should also try to get a new set of video cables as the ones you have may be internally broken.
Please follow the installation instructions carefully especially the colour codes of the video and audio cables i.e yellow cable to yellow connectors of TV and cable box , Red cable to red connectors of TV and cable box etc.
good luck!

TV doesn't respond to the remote control...can't change channels

You have to find out if the remote is sending out the infrared signal to the TV remote receiver or not, you can test that by pointing the remote at the digital camera, you should see flashing light on the camera screen when any one of the remote button is pushed (digital camera can detect infrared light). If get the flashing light then the problem is in the TV remote sensor.

It could well be the accumulation of dirt/dust behind the buttons causing them to stick. If you are able to carefully remove the board that the buttons are located on and use a cleaner that will de-grease at the same time. Be sure that everything is dry as can be before re-assembling and then check if the problem persists. If you are not capable of doing this trust a competant technician. Hope this helps.

Hisense LCD TL 3220 tv no HDMI

If your telly has no HDMI then I assume it mus have DVI instead. You can buy a DVI to HDMI adaptor from most good electrical stockists but the only problem is the financial one for the extra cost for the leads :-) Hope this helps.

Backlight spots on tv screen

When you took the light defusing screens out there was 3 screens that you removed, they need to go back in the say way they came out, you mixed them up and now the set isn't distributing the light correctly, pull the panel out again and put them back in the same way you removed them and it will work like it should, simple fix.
