Problem with Samsung P-401 DVD player

[smackman1]

This DVD player distorts the color on my TV. It plays but the colors are everywhere AT TIMES. I have cleaned the optics internally. It will work then all at once the colors just distort. I moved this DVD player to my bedroom and it started off "messed up" but has cleared up AGAIN for now. I know its not the RPTV because it was doing this on my old tv before this. This has been a on going problem for YEARS. I have come to the conclusion its not a dirty Lense or mirror because I have tore this unit down and cleaned it with pure alcohol more than once and air dryed it with can spray. I have become a Samsung expert in tearing a DVD player apart. HAHA. My philips DVD player plays without issue.

What is going on? What external interference problems could be causing this? What am I possibly overlooking internally. This player will work perfect for a month then all at once the colors go everywhere with ANY DVD I put in the player. I know this is a older player but very few DVDs have been played in this unit maybe 100. Thanks ahead for help and advice. I am a Electronic Technician but do not specialize in DVD players.

Try this without the dvd player there might be something wrong inside the t.v. maybe an electrolytic capacitor needs to be solder.

Are you getting the same results using ANY of the outputs or have you tried them all? (component Vs Svideo Vs Composite) I have worked on quite a few units and color symptoms almost always had to do with connections on the RCA connectors & on very rare occasion an encoder IC or loose connection somewhere on the main pcb. ---any laser related issue has to do with reading/playability on a disc & has no bearing on color whatsoever.

Of course, unless a connection issue, it won't be worth the trouble.
