|---|---|---|---|---|---|
| Thomson | 24WK24U ICC17 | Set is tripping with flashing from the red standby light | Short the collector of TL71 to earth, if the set comes on you will find the frame chip is blown and ZL11 cp is o/c. If the set still wont come on them the LOPT is suspect | ||
| Thomson | 28WR23EG ICC17 | AV1, AV2 are fine but AV3 do not work. Picture may be ok but no sound | Replace BA7604N, and check CX64 47pF | ||
| Thomson | ICC17 | Standby led fault codes and meanings list / standby led flashes then pauses | Code meanings are as follows: 10 = child lock mode, 11 = timer mode, 14 = there is no response from Iv01, 15 = there is no response from IS40, 20 = bus access prohibited by software, 21 = bus data line held low, 23 = bus clock line held low, 25 = switched 5v supply missing, 26 = crt is not warming in the allotted time, 27 = deflection failure more than three times, 28 = IF01 guard voltage pin 8 exceeded, 34 = no response from the nvm chip IR03, 36 = incorrect address passed to bus handler, 37 = unexpected level on NMI line power fail, 41 = bus data line not recoverable | ||
| Thomson | 28WS23E ICC17 | Set trips off int. Set tries to come on then goes back to standby | Dry joints on line o/p transformer | ||
| Thomson | 28WS23E ICC17 | At switch on set starts-up with lots of sparks inside CRT socket, then switches to standby | Replace FBT - HR 8317. There is a repair kit available from Thompson for this , which includes a new loptx, tuning caps and a couple of coils. There are also some surface mount resistor value changes. It's Pt. no: 35175720 | ||
| Ferguson | ICC17 | Dead Set | Check DP21, 39V Zener, in the startup circuit | ||
| Thomson | 24WK25US ICC17 | No/Low contrast after EHT flashover | Check/replace TL02 and TL59 in the beam limiter circuit | ||
| Ferguson | M8422U ICC17 | LED flashes once the 6 times then goes to standby | Replace LOPT | ||
| Thomson | ICC17 | Picture lacking in contrast and brightness | The symptoms suggested a beam limiter fault, replacing transistor TL02 BF422 which was found to be leaky produced excellent pictures | ||
| Thomson | W7023U ICC17 | Dead with front LED blinking 2 then 7 times | In prot mode - brown gunge around LOPTx. Fit replacement (comes a s a kit) pt no 35123670 | ||
| Thomson | ICC17 32WS23U | Trips 3 times then dead | LOPTr & LOPTx faulty | ||
| Thomson | ICC17 32WS22U | Dead - at sw on LED turns green then flashes amber twice, goes green then flashes amber 6 times & repeats | Dry joints CRT base | ||
| Thomson | ICC17 28WS23U | Tuning procedure | Sw off TV mains whilst in st/by. Hold chan - on TV whilst sw on. Full auto tune menu appears | ||
| Thomson | ICC17 28WS23U | Shuts down at sw on aft EHT rustles up | LOPTx replaced stopped shutting down but still no sound/vis - CB01 10nF 3kv in A1 supply on crt base leaky | ||
| Thomson | ICC17 28WS23U | Dead apart from Red LED that does not change | LOPTx low res turns all ways round | ||
| Thomson | ICC17 28WR25UG | Dead - no st/by light | DP21 37v zener BZX85C39 also check RP20 470R. | ||
| Thomson | ICC17 28WF25U | Int reverts to st/by with red LED flashing | May run again for a while when sw back on - leakage in focus spark gap. Fit new crt base pt no 80298800 | ||
| Thomson | ICC17 28WF25U | Dead with all volts appearing at psu o/p at 1/2 normal value briefly at sw on | The 39v I/p to TP21 chopper Tr in st/by psu low at 11 v - DP21 39v zener leaky | ||
| Thomson | ICC17 28VK24 etc | Dead with red LED blinking 2 then 7 pulses | LOPTx - comes with mod kit 35175720. Also check FOP chip IF01 & cct prot ZL11 for damage by LOPTx | ||
| Thomson | ICC17 24WK24U | Tripping with red LED in sympathy | To disable trip s/c TL17 e-c; blank raster with fb lines now present; Field fback supply missing due to ZL11 MP25 o/c |
