Re: Samsung 305T - Video Distortions
hi,
I haven't taken the panel apart,I did email a bunch of people that should know if it's the panel ,they said it was inside the panel ,but would you tell some more about the inside of the panel and is it fixable or is it replacement time,
If you are having other problems the voltages are listed aroung the plugs on the boards ,if you have a volt meter you can check these ,they should be real close to what is written on the board,a Rat shack meter will do this if you don't have one.
Those spots on the boards that are changing color are hot spots,I got a kit off ebay for all the electrolytic caps,and replaced them,mine had 2 rubycon and the rest were samyoungs I checked the first 8 with a caps testor they were out of spec so I replaced all of them,I did notice the icons/colors were much sharper after the caps were changed,
I did try to reflow the Tcon board ,The oven is the eziest the heat gun has got to keep moving and don't bump the other parts on the board as they will move and you don't want that to happen,I took some heatsinks off of old mother boards and JB welded them to the altera chip and a few around it,I got 2 fans from old computer power supplies,and used a 9volt power supply (wall plug in style),These fans must be wired red wire to plus and blk to negitive or they won't run ,I put one fan over the altera board and one at the top of the power supply board,I use quick dry bathtub silicone and boxed the edges with plastic to make the fan fit the metal where the vent holes are,It now runs very cool,
