Tv turns off after being on for only a few min.
is there a flashing indicator light on the front panel ,,likely red ? it seems the internal circuitry is sensing a fault and shutting the TV down to prevent further more costly damage to the circuit
Hello, i will list the criteria required to service TV and projector
TV`s first and foremost you require a good understanding of how TV`s
work and the ability of reading schematic diagrams, then you require a
knowledge of how printed circuit boards are patterned so you can
navigate around them to locate possible trouble spots.
then you require
1 multi meter of good quality
1 oscilloscope 20 MHz or better
1 shop service manual pertinent to your type and model of unit you wish to repair
this is a minimum requirement of test equipment you can have
you also kneed a location or locations to obtain the replacement parts you may require to complete the service task.
Now if you have all the above criteria in place then you have some hope to service your unit
a flashing red indicator on your TV usually refers to an internal
circuit failure, most modern TV`s have circuits incorporated in the
circuit design to protect good working components not involved in the
fault from further damage so the set will not power up and an indicator
light will start flashing, trouble spots can be anything like power
supply under voltage, over voltage over current, no vertical deflection,
excessive high voltage, XRAY, convergence failure,, EXT EXT,EXT,
Warning rear projection televisions can harbor in excess of 30,000 ,yes that is thousand Volts
There are and never will be user serviceable components inside LOL
Now if you are ready and require further assistance you may contact me
and i will step you through the diagnostic procedures Good
