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.
Capacitor and Power board
follow the power cord to the board. that is the main power board. the capacitors are near the top center (aprox 3/16" diamiter and 5/8" long ) three of them. replace all three . [email protected]
INPUT GOING CRAZY
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 55R6E no picture /no sound
This model set had defective LED lamps from the factory and only lasted 1000 plus hrs...You can get lamps that will last from shopjimmy that will fix the issue for about $60 with shipping. Its not a hard job changing them, just takes some patience and care when handling the screen as it's extremely fragile on most lower price sets.
