Question

i do not know what happened to my RCA model # M50WH72S

i woke up and went to turn it on and the power was already on and the screen is black and no sound. and the television wont turn off with remote or from front of t.v i have to unplug it. same thing once i plug it back in the t.v power button is on and no picture or sound and wont turn off does anyone know if i need to replace a part ? and where i could find it i dont wanna pay a lot to have someone look at it. i checked the bulb and its in good shape. please help.

Answer 1

Sound but no picture---is the lamp on?  If the lamp comes on then that means that the power supply, ballast and engine should be good---only thing left is the small signal board.  Not cheap and I dont recommend trying to replace it without some experience.

Answer 2
