Hello friends checking the lcd tv RCA L26D10, I arrive at the workshop only with the standby light, at the beginning I turned on the blank screen with a spot in the corner ........ checking the source SHP2608A-101, I found that there was no 12v voltage of pin 1,2,3 that goes to the main, and on pin 7,8 that should go 5v only 3 appear. Near the PC101 octoaclopador I found a U103 regulator that looks like a transistor is the AZ431, which was leaking since it mediates slightly on the reverse pole, I replaced it with the KIA431 .... as the replacement is the NT999. When turning it on, it gives me -5v on pin 123 where there should be 12v, I kept looking for alterations and I got to the smd transistors Q7: BA0G1G and Q4: DA0D17 ..... Which are damaged ...... they would have the kindness of Tell me what the replacement of these would be and provide me with the RCA L26D10 tv service diagram, source SHP2608A-101 On the web there is a service diagram in Chinese, but there are no specifications of the parts or data of the components. Greetings to all. I hope your support soon

Thank you very much for your help
