Make	Model	Symptom	Problem
SAMSUNG	CI623CN	Field collapse	Tda8350q s/c ; r307 10r 1/2w fusible o/c
SAMSUNG	CI6230WN	Won't come out of st/by when cold	C806 100µ 25v
SAMSUNG	CI6230WN	Tripping	C56 2u2 250v , c590 on tube pcb use 450v types
SAMSUNG	CI6230WN	Tripping	Check c560 2.2mfd 250v crt base , replace c590 as well. ( to confirm - remove crt base connector at plug near lopt )
SAMSUNG	CI6230WN	Pulsing psu & tripping	C560 2µ2 250v on crt base - also check c590 - remove plug by loptx to crt base to check this fault
SAMSUNG	CI6230WN	No r/c operation	Micro ic701 had developed internal s/c which made prot line go low- pca84c840/062
SAMSUNG	CI6230WN	Field chip has short life	Fit a 470n cap from pin 5 of the chip to deck and replace pj28 with a 10 mh choke, check elect caps, give no guarantee and hope!
SAMSUNG	CI6230WN	Dead with squeal	C416 2µ2 250v in lop supply
SAMSUNG	CI6230 UM88MT-1	Filed collapse	When replacing tda3654 fop chip also replace wire link pj28 (from pin 5 chip) with 10µh inductor pt no 2701-001040 & fit 470nf polyester cap pt no 2305-000407 between pins 4 & 5 tda3654 as close as poss to chip to prevent reoccurence
SAMSUNG	CI6230 U88MT1	This set was dead , with just a high pitched squeal	C416 ( 2.2 , uf , 250v ) was short-circuit. it decouples the supply to the line output stage.
SAMSUNG	CI6230 U88MT1	Partial or complete field collapse , replace ic301	Add 1n4148 from pin 9 ic301 to pin 3 ic 301 anode to pin 3 add 1n4148 from pin 3 ic301 , anode to ground add 12pf ceramic fr
SAMSUNG	CI6230 U88MT1	Odd video - no colour	Check 12v supply from reg.
SAMSUNG	CI6230	St/by only	C808 & 806 100µ 25v

SAMSUNG	CI6229T	Int dead or does not switch on from cold	Replace c806 100mfd25v
SAMSUNG	CI6229T	Field collapse - repeat failure of fop chip	Mod by removing link pj28 and in it's place fit a 10uh choke. also add a 470nf 100v capacitor from pin 5 of ic301 to earth. pj28 is the 26volt supply to the field ic and this rail suffer's from spike's.!
