SHARP	S3B DV5131H	Coloured lines on top	C712 100uf 35v
SHARP	S3B	Q603 lop tr 2sd1554 s/c	Evidence of overheating - check drive wfm - if low change d601, 603 & 607 1n4004
SHARP	S3B	No pic - rushing noise from spkr	9.5v supply missing - r745 0r33 o/c
SHARP	S3B	Low contrast with flashes	Bf421 tr on crt base (auto grey scale)
SHARP	S3B	Flickering pic	By299 d713 high fwd res
SHARP	EURO-DS	Off - no st/by	C707 22µ 50v
SHARP	EURO-DS	Field collapse	Ic1402 nvm3060 can be corrupted - check location 7a should be 00
SHARP	EURO DS1	Off with faint whistling	Gone
SHARP	EURO DS1	Blue screen only	Supply to ic250 pin 7 missing - c257 33µ 16v s/c & d250 2v1 zener o/c
SHARP	EURO DS	Dead low, varying ht 10-50v	Ht pot int
SHARP	DW100 66FW53H	Dead - usually ic705 opto is to blame - pt. no. rh-fx0106bmzz	Changed to rh-fx0110bmzz - when the opto fails it usually takes out the line output transistor(buh515) and the feed resistor to the line o/p stage 1r2w resistor. you need to add a 145v avalanches diode to the circuit on the print side directly beneath c720(h.t. reservoir cap) which also will need to be replaced.
