| Sharp | 66FW53H | St/by only | R714 560k start up res - also check R713 560k | ||
| Sharp | 66FW53H | Rotated pic (not horizontal) | Replaced the following in rotation control cct on crt base - IC1601 VHIBA4558F/-1 (BA4558 ic), Q1603 VS2SC2412KQ-1 (2SC2412 trans), Q1604 VS2SA1037KQ-1 (2SA1037 trans) | ||
| Sharp | 66FW53H | LOPTr repeated failure | LOPTx faulty | ||
| Sharp | 66FW53H | Dead with bang | C720 blown, R765 & 766 100R sm o/c, R623 1R o/c & Q601 BUH515 s/c, caused by opto IC501 MOC8106 | ||
| Sharp | 56FW53H | Service mode access | Switch on with vol down & Ch up buttons pressed. The ch up/down & vol up/down buttons on the handset are used to alter values & each setting must be stored by pressing St/by | ||
| Sharp | 56FW53H | No audio | IC302 (TDA7480) l/h audio o/p Ic (about 8ukp from Seme) and two chokes connected to it L315/L316 (3.3microH) (about 1.50ukp packet of 5 from Farnell) were burnt to a crisp.After replacement I still had no l/h audio, found Q306 (2SC2412 sm) s/c in the +5v feed to the Ic (I used a BC847) | ||
| Sharp | 56FW53H | Lines of R, G & B at top of screen & pin cush dist at top | Need to set up NVM values for specific crt type obtained from Sharp Tech bulletins. Also may need to alter geometry settings in service mode. | ||
| Sharp | 56FW53H | Dead - LOPTr s/c | Fit new BUH515, check for dry joints C613 & C607 330µ 10v hi esr | ||
