[QUOTE="ralphmagno, post: 623833, member: 189146"] hi to all changing a chip because the power supply is bad is not a good idea if you never soldered or worked with this don't try. print the diagram and take it to a tv repair guy. show him the cap c9 that could be bad. all the voltages will be low. the 12 v will run about 10.5 30 v will run about 22 v 5 v will run 3.8v if all voltages are good except 30 supply the problem is in the 30 supply area. anyone that repairs tv will be able to follow the diagram. depending on labor costs it may run 50 cents for parts or even a few dollars if more parts are broke. labor is another prob. the diagram above is good. i have fixed 25 of these. hope this helps ralph:) [/QUOTE]
