The modern television was never meant from the start to be a serviceable device but a disposable,pretty much as are all consumer grade electronics.
There
was a time when a TV would have actual "building block" cards with each performing a specific duty that one could pull and test outside the TV but those days are long gone and we now have high density chips that not only take the palce of hundreds of subsystems but mean you have to chuck the whole thing and start new because NONE of the interna elements are accesable or repairable.
A simple internal-chip resistor gone bad means replace the entire TV and this is not accidental but 100% intentional because while we here all this crap about "green" electronics and RoHs the landfills are becoming overloaded with mass production electronics meantr to have a lifespan of two years.The use cheap parts,are built cheap and cost little so no one seems to care that once upon a time even a novice could wrangle his way around a TV set,repair some minor part and have service counted in decades not years.
My guess is your brothers TV is not only **** up but considering replacement cost not worth getting zapped over.The "light turns orange/nothing happens" leads me to power supply section and the turn on timing being wonky with the end result of the high voltage section not firing but just wild conjecture using the evidence provided.That can mean anything from a bad switch to a bad fuse to a bad thermistor to a loose board or contact to a fried chip to........
Poking around with no clue and without the repair manual (if one even available and that not always true) means you have no idea when something either IS or IS NOT within specs.You
must have the schematic with the voltages for each point clearly marked or the end result is pissing in the wind or worse,poking and prodding until someone gets hurt or something blows up.Luck has nothing to do with modern TV repair.
So unless there is the obvious bad part that can be identified by a visual inspection or you see scorch marks or smell "burnt" plastic there is not much you can do without a bad end result.Leave HV to the experts who have a healthy fear of it and have survived years of "one hand in the pocket" probing.Chances are a repair will be more of a hassle/expensive than a replacement anyway (or buy an "old" set
) if going by the discusssion my sister had just three days ago at Circuit City means anything :
She was looking at a flat panel large screen TV purchase and doing the price compare thing when the service contract came up (another joke BTW-the sell you crap then sell you something that should be free anyway as it once was-the gurantee that if the fkn thing is garbage and blows up they will make it right
)
Sister "how come the service contract is so high"
Salesman "because the TV does not get repaired but replaced with a new one.they are not serviceable"
Welcome to the future
