Question about Sony KP-46WT510 46" Rear Projection HDTV
I have a convergence problem it is dipping at the top of the screen. All colors are visible was told it needs the color convergence chip replaced..do you know the part # and where I can order one..Also need a service manuel and sony remote to reset after repair..Can't pay a mint in labor cost. Would appreciate any info you can provide...
The system will not let me post to a link, I wrote: OK first off, as you stated, you will for sure need an original replacement remote for this TV set to make any types of alignments. You may also have a friend relative or maybe a neighbor who may have a remote you could borrow. If not, there is one available here http://www.remotes.com/remotes/servlet/rs?a=gmi&smodel=KP46WT510&brand_pn=SONY_KP46WT510&mode=large&uid=11859736726080 Now the convergence IC's, there are two of them that will need to be replaced, the number is STK392-560 You can get the original Sanyo IC's from HERE http://www.mcminone.com/search.asp?keyword=STK392-560&btnSubmit.x=10&btnSubmit.y=8 You will also need to get some heat sink compound and apply to the backs of the new IC's before you install them. Now after all is said and done, before you plug in the set, take a multimeter and check resistors R 8122,and resistor R8127. These two resistors supply the voltage to the IC's. They are 7.5 ohm resistors. The R8122 carries the negative 22 volts and the R8127 brings the positive voltage to the IC's. Next, check the circuit protectors around the IC's also. They are PS8001,8002,8003,8004,8005 and PS8006 and make sure these are not open. These circuit protectors are nothing more then 3.2 amp fuses. I do not have the KP46WT510 service manual, so you will have to go to servicemanuals.net Good Luck
