Make	Model	Symptom	Problem
THOMSON	55MT16	Tsound is no sound	Ta02
THOMSON	CHASSIS ICC9	Loses synchro line and plot	Th05 - th04 - tx16
THOMSON	CHASSIS ICC9	Stays on standby	Tp66 and tp69 in power supply
THOMSON	14MG10G	Blue screen with feedback lines	Transistor TT72/2SC2482 with base/collector leakage
SABA/THOMSON	CHASSI TX805	Zener dp50 breakdown	Check welding from pin 5 of the tsl to the electrolytic cp17
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	TX91	Pll will not lock for all frequencies keeps running during program search, on screen display moving / unstable	Changed the tuner and the stv8224 also check transistor at location tv02 is ok
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 = tsound is no response from iv01, 15 = tsound 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	ICC20	Set tries to start three times, hv comes up for a short moment. after this led is blinking first four times, then seven times	Change vertical chip tda8177f and the four diodes in front of it
THOMSON	TX807	Eht at switch on then goes dead	Frame i.c. s/c tda8177
THOMSON	28WS23E ICC17	At switch on set starts-up with lots of sparks inside crt socket, then switches to standby	Replace fbt - hr 8317. tsound is a repair kit available from thompson for this , which includes a new loptx, tuning caps and a couple of coils. tsound are also some surface mount resistor value changes. it's pt. no: 35175720
THOMSON	24WK25US ICC17	No/low contrast after eht flashover	Check/replace tl02 and tl59 in the beam limiter circuit
THOMSON	TX807	Plain raster, retrace lines, no sound	Problem in vif board, resistor 68Ω to +b supply line 12v
THOMSON	28VK-44E	No start-up when cold, warm ok	Changes cp198 47uf, 16v. secondary power supply
THOMSON	RP46	East-west and north-south bowing. really bad convergence	The extra power supply is not working. check r18 on primary side. it should read 220kΩ
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 FERGUSON	14CB25UT C3615UT	No pic - sound ok but reverts to st/by aft 5-10secs	Dl07-by228 in e/w stage
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
