Hi I have a Bush LED26982HDT when i first turn it on it'll be okay for a short while then it'll turn itself off then when I turn it back on it will turn itself off again very shortly after I turned it on any ideas on what it could be? And this is the second TV of this make and model I have gotten in the past 2 days I am not impressed with Bush

SOURCE: TV has green sceen and turns off by itself

SOURCE: TV turns on, then immediately off again

The flyback transformer are damaged.

it could be a ghost but most likely a bad solder connection , crystal(controls the eprom)(menu chip) , or the eprom chip itself will need to be replaced

SOURCE: I turn the tv on and after a few seconds it shuts

Possibly the main Power Regulator is damaged!!!

Open the case, then look for anything that burned out, replace it!!!

If still won't start, you need a multimeter, soldering iron, try locate output diode on power regulator board, then measure the voltages, it has 3-4 type of voltages;
first diode it should around 115V-130 V DC.
Second diode it should around 24 V DC.
Third diode it should around 11-16 V DC.
Fourth ( if exist), check diode and should around 5 V DC.

The problems usually start on second diode, if persist, follow the circuit board.
