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....
You almost certainly have a bad picture tube. The green screen was from one of the elements inside shorting out. The static sound you're hearing is the high voltage arcing out through the end of the picture tube to other parts inside the set. It's more economical to buy a new TV than to repair this one.
Sorry to have such good news, but this is one of the ways a picture tube can go bad, and it happens quite often.
Pull the back Off Disconnect CRT board connected at End of picture tube then turn set on and see if it comes on with volume, high voltage you can feel front of tv for static elect.... Let me know what happens then i can tell you what is wrong with TV.
Self test: Turn on and Press the input and menu buttons on front panel together and hold for 5 sec. after 5 sec the power LED will blink a 2 digit seq. This will let you know what error code. Count the first blinks then a short pause then the second blinks. Example 2-3, 3-4, 4-1. Let us know what it is.
If the picture is oK and no sound. The first possible problem or trouble is the speaker. It may be broken, open, otherwise defective. Second is the phone jack on your TV set. Third is the amplifier. Just check all this mentioned parts.
