First, let me say thank you to everyone who's posted on the convergence issues-- I've replaced the convergence ICs and my TV is working great again, mostly.
After putting everything back together (with pictures, all cables and connections labeled, etc.), I cannot get any video to work on the composite or s-video inputs. The AV4 HD input works fine, and all of the audio inputs work fine. But nothing works on AV1, AV2 or AV3 composite or s-video inputs. I've looked around to see if I missed a connection and I don't see any. Does anybody have any ideas? Does anybody know which part of the electronics boards handles the composite and s-video inputs? Thanks!

Re: Composite and s-video inputs stopped working
You may have shifted the input board a little while replaceing the IC's. Double check every plug and connector, not just by visuale inspection, but by going and removing and replacing every connector. I have had problems like this in the pasy and have learned the hard way, everything is not as it looks. Good Luck

I'm having the same problem with my Wii output. The manual for the Denon AVR-1312 says that analog video signals (i.e. component/composite outputs from the Wii) are not converted to digital video signals (i.e. HDMI output from the rcvr). I'm running only HDMI to a projector, so the video signal is essentially lost. The fix appears to be to run an additional composite cable all the way to the projector. Sounds like your fix is the same. No Wii tonight! :(
The pictures show the result of a bad terminal input board. You can verify this by checking the inputs. Connect devices to the board and try different inputs. You will most likely find this problem on the tuner and component input were your DVI and composite video will be ok. If it is the same on all inputs replace the A board
You brought up an issue that we hadn't considered. Shortly after hooking up our TV to the receiver with a composite video, our convergence which wacko. My hubby replaced the 2 ICs, but now our power button just flashes red, with no picture. Not sure if new ICs are faulty or if it's another issue. He will replace old ICs to see if problem still exists with turning on the tube. And he'll try disconnecting the video signal to see if problem exists.
Ouch.. may have to consider another tv thanks to new technology ??????
have you check the electrolytic filters. check the video IC. also check the polyster or disk type capacitor, because they hold the frequency. in on screen mode the half of section is dead, but when you applied a signal it start converting it display mode. every signal is extracted from video signal in TV mode. the best way to check all this properly you need a colour pateran generator. when you used it you will find a fault and the area.
best of luck...
