| Sharp | 66FW-53H DA100 | Dead - LOPTr s/c, C720 100µ 200v split open | opto-coupler (IC705) and the two damaged components above (Q601 & C720). Fit avalanche diode across C720
to prevent future damage (cathode to positive). A new TEA5101A (IC1801) was also fitted on the CRT panel as a precaution | 14-09-04 |
| Sharp | 66FW-53H DA100 | Stuck in standby ,only orange LED | Replace opto coupler IC705, Q601 (BUH 515), Q5408 / Q5407 and R5425 (470ohm) on tube base. C720 (200V/100uf.) Add avalanche diode RH-EX0875BMZZ across C720 | 14-09-04 |
