Philips TV model 34PW9815 the LED on the front of the unit turns green when first plugged into electrical outlet, and then immediately starts to flash red. nothing on the unit works and it doesnt respond to controls either on the set or the remote
hola,tengo un reproductor de musica y a estado parado un tiempo,y ahora al enchufarlo se le enciende la luz de standby en rojo y no en verde como deveria ser.a que es devido este problema?1 saludo y gracias
the high voltage or flyback transformer is not working.the sound runs off a separate fixed power supply.if you run your hand across the screen,is there static?that would mean the high voltage is ok but there is another circuit fault
Sorry to say, but that's usually the sign of a bad picture tube. One of the elements inside the tube shorts and you see the picture you describe, and the set shuts down due to high voltages getting to places it shouldn't. There's no solution except picture tube replacement, and that is uneconomical. You're better off replacing the TV when the tube goes bad.
A qualified tech will need to practice visual
acuity technique! Look at power supply circuit
for signs of stress,dis-coloration and/or bad
connects.Check for bad 47mf/25v cap in area
of stress.Replace BC-327-25 xistor w/BC-328 and
replace BC-337-25 w/BC-338,if present in your
set's chassis style.
