Hi Folks,

Have one of these where backlight is constant but picture fades in and out - sound OK. Have cleaned the LVDS lead - but no better. 17PW20 and 17MB22-2

Any ideas ? Chris.

Check screen
if screen Samsung something like 320 -L05
and have picture like slow moving
then screen is faulty

Hi, and thanks Mulja,

  Screen is Chi-Mei V320B1-L04 Drive panel V320B1-C04 Picture quality appears poor in definition compared with many others.

  Not Samsung, but the numbers are similar. Thought to take off the drive board screen - tapping the board provoked the fault, wonder if anyone does a reflow ?

  Thanks again - Chris.

Hi Folks,

Re-flowed solder on a couple of large chips on screen drive panel, and apart from an initial short as I couldn't quite see the pins clearly - all seems well.

Any thoughts on an improved eyeglass ? - Chris.

Hi Folks,

Must confess that after a few days the picture flickered dark just before customer was to call to collect. He was so impressed by Quuq 'Vestel' relevations that he left a tenner for my pension funds.

Who says we never win ? - Chris.

P.S. Note that CPS does a USB microscopic viewer - anyone tried one, and also, how to align one's sight and iron with the pics ?
