Hi there i have a 7 year old panasonic rear projection television model number pt-51g46C that will not allow the green to converge rpoperly everything seems to have a green halo and there are waves associated with the green crt. when you dim the crt the green one seems to me to have missing pieces but according to eevrything i read i need a new convergence ic. so i waited for 3 weeks and recieved my 3 new ics soldered them in and the problem is exactly the same. I am unable to check for power to te ics when it is powered up due to the lack of room burried in the front of the television. i checked all teh resistors i could think of when the board was out. i am thinking this is my problem now and am having a hard time finding any info on this set. i called panasonic and they informed me that they no longer have this repair manual anymore? and for me the nearest place for repair is 2 hours away. I think i am on the right track and am not ready to throw the towel in as of yet..

thank you

therer are small fuses or pico fuses in the power supply that are probably open. Find and check those.

thanks larry where would i find these fuses on the convergence board or on the power supply board?

also would you happen to have a wiring schematic for this model?

okay so i have the power supply board out on this unit and there is only one fuse the 125 volt 7 amp one. i cannot see any pico fuses nor can i find them labeled on the board?? are they labeled with a f before the number just like any other fuse.

they couls be, I have sen some marked with an R as they may use low value reistiors for fuse links, you should get the service manual for this set. you cn download one from here

okay so i decided to tear into her again and everything looks in tact i went around the green ic and all resistors have a value except for this one thing that looks like a resistor but is just all brown?? it is marked with a C and labeled as C 7092 and has no continuity through it when all the others like it do... http://i228.photobucket.com/albums/ee76/jim_rench/100_1944-1.jpg[/IMG]" alt="" align="middle" /> i am awaiting someone with a CC to allow me to buy the service manual but in the meantime i am just looking at it apart in my living room....

Photobucket

now this is the only one i see burnt out

it is pre near impossible for me to check for voltages with the board in the unit powered up is there anywhere else i should look and where do you recomend purchasing a .1UF-Z-50V capacitor? part number ECUX1H104ZFX.

thanks a bunch
