Samsung Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| 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 | CI6230 | No sound - ok via scart | Audio in at tda8415 ic601 ok but no o/p - no osc due to 10mhz xtal being u/s | ||
| SAMSUNG | CI6230 | Field non lin and short pic | 4 | ||
| SAMSUNG | CI6230 | Dim heaters, non lin field, hum bar on cols - all line derived supplies low | C560 4.7uf @ 250v & c590 2.2uf @250v on crt base | ||
| SAMSUNG | CI6230 | Dead | C416 2µ2 250v blasted - check d814 s/c ru4am - byw95c does | ||
| SAMSUNG | CI6229T P72 | No pic unless a1 advanced - looks like failing mono tube | C416 2µ2 250v ht decoupler | ||
| 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.! | ||
| SAMSUNG | CI6229 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 | CI5955N | Field collapse | Replaced tda8350q & r412 0r27 |
