| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| sharp | 70AS | Line transistor goes S/C after short time | R619 + R620 (39R), L600, L602, L603, C617, C618 + C615.drive at Q606 has to be > 2 V pp check also IC 800 | ||
| Sharp | 66W53 | Failure of Q601 & Q506 | Dry joints C613, change R610 safety, L603 coil rcilp0286bmzz, line tr Q506 e/w tr rh-tx0144bmzz | ||
| Sharp | 66GS62H GA10 | E/W poor & pic breathing | D624 SMD HDX00551BMZZ. | ||
| Sharp | 66GF64H | Blows LOPTr & C720 at sw on from cold | ic 705 & d735 pt no.s rh-fx0110bmzz & rh-exo875bmzz (available from CHS) | ||
| Sharp | 66GF63H | Sound - crackling/int missing - no vol bar movement | Dry joints small audio sub pane | ||
| Sharp | 66GF63H | Dead with psu clicking | Check LOPTr & fit 3 x opto coupler kits (1 psu, 2 data) | ||
| Sharp | 66GF63H | Dead with D735 (EX0875 or BZW104) s/c | Replace PSU opto - kit available but without D735 | ||
| Sharp | 66GF63H | Bright raster with fback lines | pin 2 IC1801 on CRT only 2V caused by Q912 o/c BC337-40 (Sharp special - normal one overheats) Also check D1805 & C1815 both sm on crt base | ||
| Sharp | 66GF63H | Bright picture F/B lines. 2 volts on pin 2 of ic1801 | Q912 O/C. Replace q912, d1805 & c1815 | ||
| Sharp | 66FW54H | Int red pic | O/P IC on crt base faulty | ||
| Sharp | 66FW-53H DA50W | LOPTr BUH515 fails at sw on | Check for dry joints in line driver & o/p stages & replace C607 33025v in driver | ||
| Sharp | 66FW53H DA50W | Sound dist | IC1300 sm chip on plug in pcb overheats & contaminates board - exchange boards reasonable price pt no DUNTK7285BMW1 | ||
| Sharp | 66FW53H DA50W | Contrast level reduces aft 20 mins | IC1801 TEA5101B RGB chip on crt base | ||
| 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 | ||
| 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 |
