Hi Tony,

   Thanks for making things simpler for one initially looking for the 'Picture valve'  Did as you suggested, and the now have the top half of the picture.
   What do you suggest next, noting that earlier you said that replacing the Y-SUS as well would be the business - does the Y-SUS tend to pop the drive boards perhaps ?

Hi folks, esp Tv Tony,

    While waiting Tony's further thoughts, Just had to plug in replacement lower drive board and was rewarded with a normal picture. Still a bit concerned as the Ysus tends to buzz a bit. Is this normal or reason to replace it. Got a screen smash locally, so lots of LG bits.

    Many Thanks - Chris Steele.

If it's an LG 42V6 panel then yes, I would definately recommend changing the Y-Sus (6871QYH029A - Now 6871QYH029R), or you'll be looking for another 6871QDH067B Lower Buffer very soon.

Good Luck

Hello, and thanks to aoi3610,

   Replacement Y-sus in place and all well. 

        Thanks again - Chris Steele
