Question about Himage HJ-2205
My DVD player is plugged in to the wall receptacle, however there is no power to the unit. I took it apart and see nothing wrong with the circuit boards. The fuses are good and there are no burned components. So I suspect a bad transformer coil or something of that nature. Any ideas on where I can obtain replacement parts? Or at least how to check these? Any help would be appreciated. Thank you.
25 years of experience should help one get out the old multimeter and measure voltages. Suspicion does not help :) Here we have a saying 'meten is weten, gissen is missen' 'to measure is to know, to guess is to miss'
Most of the dvd player have a switching power supply so you could start from the power switch and see if the ps board get's mains power, from there on move on down to checking voltages at the output (red/yellow/black/white wires running to cpu board and dvd player).

Ok 2 things i would suggest here ...
1. Try another appliance ( that is currently working ) thus eliminating the chance of a faulty power outlet.
2. Secondly, depending on the brand name .. some newer units seem to have a life span of 1 - 5 years, 5 if it was operated in the right conditions ( ie: not damp or dusty ) and considerably less if the unit was operated by children with curious or sticky fingers.
Now presuming the unit isn't brand new ( or you would have simply returned it for a warranty claim ) the next best option here is to consider that DVD players are quite cheap and inexpensive.
Ok so granted this is neither a solution nor a quick fix to your problem, but i trust you will consider keeping your fingers off the circuit board and away from the power supply for your own safety. Some larger components (ie: capacitor ) store large amounts of power and touching them with a metal object may allow them to discharge to earth ... via whatever it is you may have in your hand at the time.
My advice, leave the cover on and take the unit to a repair shop for a quote.
