At 10:20, Very interesting what happened to the diode - a matter of poor contact. I learned something new.

Hello.the great tevz TV, I have 29 inch LG CRT TV(CN-29H3) which won't display any screen But It surely lit its led lamp ,whenever I plugin ac cable. It is written "MC-7CA(MAIN) 6870VM0056C(6) 980424 L.W.G(0)" and "MC-7CA(CPT) 6870VS0167A(1) 971014 K.J.B(0)" on the surface of its PCB. I plug in this 29inch CRT TV,and switched on ,then I measured pin#9 of STR-S6707 by placing red probe of analog meter to pin#9 and placing black probe to negative termainal of C808 the biggest capacitor(400v 470uf) and It was measured 6.4-6.6Vdc. But In the datasheet of STR-S6707,It says that its On-State Voltage is 7.6Vdc.So I think that there would be a defective component which is undoubtedly adjacent to pin#9 of STR-S6707. And In the same way,I measured cathode of ZD808 zener diode and Q800(C3852A)base,It was measured 7.1Vdc. I also measured positive terminal of C805 and cathode of D807 and Q800(C3852A)collector,It was measured 10.8Vdc. i found The big capacitor(160v 100uf) on the cold side,I think that it is the B+ filter capacitor,So I measured it and It was measured 39-40Vdc. I desoldered all of electrolytic capacitor which is nearby STR-S6707 and measured its capacitance and ESR value But It seems that all of electrolytic capacitor seem to be Okay.and I also measured most of carbon resistor and diode which is nearby STR-S6707,But It seems that all of resistor and diode seems to be Okay.. Is there no way to find any clue for repairing this CRT TV?

2:00 quiero hacerle una observación: He notado que casi nunca limpia usted los equipos que está usted reparando, la verdad me apena decirlo pero eso no es muy agradable para trabajar así pues a veces se encuentra un daño oculto en las pistas sucias y/o cables llenos de telas de arañas, espero no se ofenda y me gustaría saber porqué razón no limpia si es por falta de tiempo o porque cobra muy poco dinero por el trabajo, o porque no valen la pena los aparatos que está reparando?, me gustaría saber la razón, saludos desde México.
