Question about JVC Televison & Video
The blinking light is an indication that the set is in protective shutdown. A problem has been detected and the set is shutdown to prevent further damage. While a poor solder connection could be the cause here, there is also the possibility that a defective component is the problem. Does the light blink in any type of pattern? Usually theprotective shutdown will trigger an indication circuit that will blink the light a different count depending upon what type of defect was detected. CAn you post that count here?
JVC sets are difficult because service information is not available outside of authorized service centers. Whether the problem is a bad connection or defective part, it is most likely within the power supply area.
Please keep us posted.

Cold solder issues - each
component is soldered into small
holes on the printed circuit board which in turn connects said
component to the
other components. Due to time, heat, use, some solder joints would be
or loose. It is possible that the cold solder is still minimally
(hanging by a thread). When the LCD TV turns on heat would be
generated which would
be sufficient to further loosen up the solder joint to the point it no
provides electrical contact. Jarring the unit creates movement inside
re establish the contact, sometime good enough sometimes not enough.
Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".
Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....

It goes on stand by because of overheating, if it is a traditional projection tv it is usually a ballast problem or a problem on main pcb board. If it is a LCD , Plasma etc, it can also be the external poer adapter giving overvoltage after a while.
In first case you need a tv repaiman in second test and eventually replace power adapter.
