Question about Philips Magnavox 27MS343S 27" TV
I have a 9 year-old Phillips Magnavox 27". I just bragged on it earlier in the week. When turned on this morning, the screen was white but the sound (from Satellite) was fine. After 2 or 3 seconds, it turned itself off (screen shows a prim of sort in the middle as it shuts off). I let it sit until tonight and got the same thing. I unplugged the power supply and cable input and re-plugged them. No dice. As you can tell, I'm not that technical. Any ideas? Unless it is something really easy, I'll have to get a repair man. If you do have any ideas, how much could it set me back? I need to squeeze another year or so out of this tv. Thanks for your help. I do appreciate it.
Replace the 10 ohm resistor on the CRT board feeding the boost voltage to the video output IC.

Hi If you mean thin white lines, this is is an indication of a problem in the Horizontal Drive ckt. most likely the Damper Diode has opened or shorted, this would cause the visual symptom and then the set would shut down, unfortunately this is a problem best left to a qualified technician to repair, hope this helps.
