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.

Check the fittings of audio output IC; to its heat sink. If it is loose, this kind of fault can occur due to IC overheat.

that problem is usually cause of shorted fly-back transformer that give a very high voltage you can find that by hanging all secondary connection of fly-back then power it again then use your multimeter and range it to dc then ground the black prove to the body of your unit test the b-plus voltage if the supply is flickering it means your fly-back is shorted and if the supply is stable it means you have a shorted diode in secondary thank you

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!

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.

Sounds like a loose connection somewhere.

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.
