| 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 highpitched 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 | TDA3654 | ||
| 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 | ||
| Samsung | CI5944 SCT12B | Field & E/W problems | IC301 fails - SEME supply kit RK12 |
