Question about NEC PlasmaSync 61MP1 61 in. Television
My plasma only shows half picture
1. Remove the rear cover 2. remove the perforated large shield on the
main board housing (almost in center). 3. Unplug the right top fan and
temp sensor plugs ( two small plugs at the top of the main board). 4.
Remove screwsthat secure the main board housing, there is also four
screws by the video inputs. Do not unplug the board, just gently pull
it away 6 to 8 inches. 5. Remove the cover with the Top fan attached
(more screws). 6. Now the scan board for the top half of the screen is
exposed. The board has four large heat sinks with two large
Electrolytic aluminum caps next to each heat sink. 7. The problem caps
are at the very top right side of the scan board C192 Nichicon 220 uf
next to the IC, the other cap is C120 100UF on the lower side of the IC
next to a heat sink. I replaced them without taking the board out. C192
is the one that failed, the other one tested OK but I replaced both.
I got the caps from Mouser.com they are 69 cents each, the Mouser part number for the 220Uf is: 647-UUD1C221MCL1GS (Nichicon 220uFm 16V 6.3x7.7 mm surface mount); the 100uF is:647-UUD1E101MCL (Nichicon 100uF 25V 6.3x7.7mm), both are 105 degree C. I bought two extra spares in case I need them for the future.
Reassemble the unit in the reverse order and you are done. Note if you test it without closing everything, make sure you have the main board shield back on, otherwise the screen will bleed due to the noise from the board. good luck! mine has been working fine.. just like new..

I have the same problem, except it is the bottom half of the screen missing on a PX-61XM1G Plasma Monitor. Any suggestions?
