[QUOTE="garga pista, post: 1089517, member: 321281"] Hello! I'm trying to repair an LT-8700 receiver, looking for a schematic or service manual, or just an advise. It works "halfway". The receiver boots up, front panel display and remote works, but no picture output. No picture, nor OSD on the TV scart, RCA plug, or on the modulator. The receiver had D2mac and Videocrypt decoder boards, I've removed both, it works without that 2 panels, but still no picture. But on the VCR scart i can get "sparklies", changing the channels seems working, but no OSD on the VCR scart :( But if a connect an another receiver on the VCR scart, the receiver switches to it, on the decoder phono out comes out the picture (still without osd). PSU works, all the voltages measured correct. Does someone has any advice? I've made some pictures from the inside, it looks interesting, that there's a vertical panel in the back with 3 connectors. From the 3 connectors, one has a lot of cables running different places in the main board. Is this normal, or is it retrofitted?
