I am working with a Mitsubishi VS-5041 with normal audio and OSD but no video at all, either from tuner or external inputs. I brought the chassis to the workshop and at the moment I can not perform any live tests. I checked the usual problems with this set but R509, R519, D726, C763 and C256 wich are the usual culprits are ok. I performed a lot more measurements and could not find anything wrong. Now I must go on at the customer's without any schematics and I would, of course appreciate any info you have on this problem, This set uses the same chassis as the 5042, 5043, 5051, 5052 and 5055.
