What is the plasma panel in this model? LG, Samsung, Fujitsu-Hitachi?

Any tips for what to look for or how to troubleshoot?
I have found a couple of swollen caps on PS bd in the Buffer power supply area, what should Va be reading, 70V?, the 2 swollen caps are located under the heatsinks (one each side) seen clearer in the second photo, pictures to follow:
Swollen caps could certainly cause your issue. Will await pics.

Connector SY
D5V measured as 5.1v
Vg measured as 14.93v
VScan measured as 188.3v
Vset measured as 196v
VS measured as 204v
Connector SX
VS measured as 204
Ve measured as 108
Va measured as 14.93
D5V measured as 5.1v
Cn8005 (Buffer)
Va measured as 69.4v
D5v measured as 5.1v
I could be reading the label on the connector SY wrong, is there such a thing as Vg or is that Va, in which case 14.93v is considerably low as Va should be 70v according to the label on the Panel which reads
Va 70v
Vsc -190v
Vs 209v
Ve 110v
Vset 198v
Following this manual there are no error detection codes on the PS alarm board, the LED just comes on solid as do the 2 leds on the PS board.
i.e remove all connectors except mains input, place jumpers on relevant pins on all 3 connectors as indicated and power up.
If LEDs are on control board these are NOT fault indicators but in fact status OK indicators.

Having repaired the wiring harness the tv has no change on picture.
Now I'm getting 8 blinks from the Error Bd on the PS bd, No Ve, and yet when I do the PS board test according to the Service Manual it all checks out ok. So it must be logic bd playing up.
