While watching the olympics tonight the TV suddenly shut itself off. After unplugging it for about 10 minutes and plugging it back in the power seemed to come back however the TV does not "turn on" or at least does not provide a picture. Instead there is a flashing RED light next to the power light (normally it is green).
If anyone knows what the flashing red light means (and more importantly how to fix it) please let me know. If the TV blew a fuse, where is it so it can be replaced?
a 6ya expert can help you resolve that issue over the phone in a minute or two.

The TV was making the clicking noise and not turning on because an internal error was being detected.
Now things had got worse , and something had blown inside the TV.
The burning smell and high pitched noise is coming either from Flyback transformer or PSU board. Repair is a delicate matter and must be done by a technician.
has TV worked before
how many hours has TV been used
I have seen this 'ShutDown' on many failing monitors..
Typicaly the Power Supply circuit in your TV
have 'Over Current' detection\protection
and your 10 second is just about how long somthing is probly taking to either:
over current and shut down
or more specifically:
one or both things wrong with it:
bad electrolytic capacitors ( maybe )
but if it's a perfect picture for all 10 seconds then probobly some specific semiconductor or module is: 'Heating Up' then 'OverTemperature' and failing in a manner that causes an immediate overcurrent condition, shutting off the TV.
- give more information
- if capable of safely removing the back of the TV to allow for inspection... , WITHOUT GETTING ELECTROCUTED
by the high voltage that remains stored inside the tube, even after power has been removed !
then pop her open and have a look at the PCB's ( circuit boards )
if somthing has been running hot and has led to this type of failure; then your circuit board will be discolored near the mounting of that device... You may even notice a burnt pcb smell at that area.
somtimes you can find these semiconductors or modules in catalogs or online ( OfCourse )
and yourself or sombody with sufficient knowledge of soldering and the
' Potentially Life Threatening Hazzardes ' that exist around CRT monitor repair....
The color problems are caused by cracked/broken solder joints on the circuit that controls the display.
Usually this is located at the back of the tube on a small circuit board. Your description suggests that only the blue signal circuit is intact. I suggest these joints be resoldered for more strength.
It's a possibility that another IC senses this problem (or another one) and then shuts down the system.
Resolder those joints and see what happens.
