| SHARP | C1430 | Tv parada. Tem os 300v no coletor de Q701, mas na base e emissor tem só 0,4v em vez de 114v | C706 em curto | ||
| Sharp | CV2123 CS | Field fault / general modification | Add a 1N4148 diode from the emitter of Q509 to cathode of D513 cathode to emitter of Q509, Pt No. RH-DX0045BMZZ, change R534 to 390ohms Pt No. VRS-TV1JD391J and add a fuse in series with L607 and L608 Pt No. QFS-J1023CEZZ | ||
| Sharp | 66FW53 widescreen DA-100 , 50 and 100Hz series | E/W fault | Coil L603 part num RCILP0286BMZZ had severely burnt up and Q506 E/W driver 2SD2391 Part num RH-TX0151BMZZ was short circuit. If you have this fault check L604 for invisible dry joints, if you don't you may find you still have an E/W fault when you have replaced the faulty parts | ||
| Sharp | DV3760H | Dead, led flashing red/green at first, then going to red standby | Replace C604 1000uF, 16v elec. cap. It is in the decoupling circuit for the 5 volt supply | ||

| Sharp | 66FW53H | Dead - neon lit ... another fault! | Check the BZW04145 diode across C720, if short circuit, replace and also replace opto-isolator IC704 MOC8106 and IC706 TL431 voltage reference. You can put an 817 opto-coupler in diagonally | ||
| Sharp | 66FW53H | Colours ramping, poor greyscale | Replace IC1002/3, Set will need reprogramming afterwards | ||
| Sharp | 51DT25H U | No audio R305 o/c | R305 2.2ohm, Q3021 BC636, Q3011 BC635 | ||
