Re: Samsung LA37B530P7F LED TV - Whitewash
latest update is if I open the ribbon cable clip on the right hand panel board and manipulate the cable I can occasionally get a perfect picture. Is it
Worth replacing the right panel board?

Next round of measurements.
Table 1 is voltages at T-con with neither voltages attached.
Table 2 is voltages across the two panel boards including the unmarked points just following down the line.
Any further suggestions?...Leave a comment:

Hi all again,
So I replaced the t-con board and I am still getting the same whitewashed image across the entire panel.
I have attached the voltage readings with the new board in place, i also took some extra readings with bits disconnected to see if that helps figure it out.
By left and right board disconnected, I mean the two boards found under the panel which connect off the bottom of the t-con board. Right and left sides are when viewed from the back of the tv looking forward.

Samsung LA37B530P7F LED TV - Whitewash
Hi Members,
I was wondering if anyone could offer some guidance in regards to whitewashing that is occurring on my TV.
Attached are pictures of the display as it normally occurs, over exposed with white. If i disconnect the left board from the T-Con board then the image on the right hand side appears normal, but whenever the left board is connected it is washed out. Earthing the pads or moving the left board, or T-con board make no differences on the picture.
My initial guess was to just replace the T-Con board as its relatively cheap and easy to... -
