42pc1d control board swap

[azza1234]

brought this tv and fixed it as in other post but was left with the red sparkle problem so far have found two people on here willing to flash a new firmware on the control board but thought i would look on the net for a newer control board so found one on ebay and won it for £2.20 but on the auction it says will not fix the red sparkle problem http://www.ebay.co.uk/itm/2614520905...#ht_728wt_1305
yet on another site someone posted

I got my LG 42PC1D plasma back, and replacing the controller board fixed my red dot issue. I inspected it both with no signal, as well as while watching both SD and HD content. I couldnt find any red dots. So it fixed the problem, hopefully for good. I also had problems with HDMI sound cutting out, and they replaced the main PCB board for that, and thats okay too in case anyone has that problem. Part and part number are below for red dots:

Part: Controller PCB
Part # : 6871QCHO77C

now that part# is the one ive just won so do you reckon it will fix the red sparkle problem for me? many thanks

Re: 42pc1d control board swap

The sparklies problem is caused by the plasma panel wearing out; it drifts and the drive waveforms (generated by the Y-sus and Z-sus under control of the control board) are no longer sufficient for good picture quality.

An update to the control board is required which fixes this issue, by uploading new firmware designed to compensate for the panel aging.

It's possible a new board will have an earlier life timer, so for a few hours or days it might work right. But it is not the correct fix and the sparklies will return within short order.

You need to get the board flashed.
