At first my unit gave me the 3d effect so I bought the convergence chips from ebay, installed them, and installed 15 new resistors out of the 20 even though i assume they were fine. I then replaced all 6 pico fuses with new ones and it didnt fix the problem, then i realized the 2 pico fuses on the g board, so i replaced the one that was bad which was the top one, i turned the system on and it worked fine, turned it on about an hour later and the resistors i replaced burned, 5 of them, which is a row, (the second group of five )to be exact right under the ic chip on the left. so i replaced the 5 with 4.7 1.2w 5% resistors, then i replaced the 2 pico fuses on the g board with 5amp 125v pico, and turned the unit on and it didnt fix anything, at this point i dont know what went wrong, or what the problem is, any help would be aprecciated greatly
SOURCE: replace a fuse R52WM24
you can temporarially. Its recomended not to exceed fuse ratings especially the amperage do to pretective reasons. You can get the proper FL231 fuse at the following link. They have a 10.00 minimum order for free shipping so you may have to order enough fuses to add up to 10.00 or pay for shipping if under 10.00 Heres the link.

I can help with the PICOFUSES...they are 4 amp Pico.
As for the resistors, if ANY are burned, look at the convergence amp next to the damaged ones...those resistors are a mirror-image of the damaged ones.
You NORMALLY do not need to replace the resistors, ONLY the picofuses.
SOURCE: I got a 5amp pico fuse instead of 4amp is that
well if i remember correctly there 3.6 arnt they so 4 its a fuse or circuit protector which open when the current load becomes excessive so by increasing the pico size your defeating the porpose of it and fi its truely a 4 amp you would want to put the same exacat back in hope this helped
