Question about Sony KP-46WT510 46" Rear Projection HDTV
Ok here's what I have. The convergence went out. As per previous suggestions I've obtained the 2 convergence chips. I've removed the board and decided to check the fuses (PS8001 to PS8006) and chip power supply resistors (R8122 and 8127). PS8003 is open and I'll replace it. However, the two resistors on the board are jumperwires and not resistors. The board has the R #s correct and shows a resistor yet there are jumpers in this location (0 ohms). Do I leave this as is since it worked for 3 years or replace with resistors? If so do they need to be higher wattage power resistors? And since the fuse 8003 was bad should I still replace the convergence chips or put the board back in and give it a try after replacing the fuse? Any help would be appreciated. Thanks.
No leave the jumpers in and yes replace the chips as that's why the fuse blew so it would not take out the power supply when they shorted. I hope you did get the right IC's, the ones that say Sanyo on them. If you did not, these replacement IC's you purchased are the factory rejects and may work for a short time, but not for long. Also do not forget to apply an ample amount of heat sink compound on the backs of the new IC's before you install them. Good Luck
