Alguma fuga da alta para o ferrite do transformador de linhas e pouco brilhoFuga da alta, saltou para o TL02 BF422 e causou com pouco brilhoTransformador de linhas 40330-56,10642070 HR8540 e TL02 BF422Paulo Costa
Thomson 24WK24U ICC17
Set is tripping with flashing from the red standby lightShort 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

At switch on set starts-up with lots of sparks inside CRT socket, then switches to standbyReplace 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

Dead SetCheck DP21, 39V Zener, in the startup circuit
Thomson 24WK25US ICC17
No/Low contrast after EHT flashoverCheck/replace TL02 and TL59 in the beam limiter circuit
Ferguson M8422U ICC17
LED flashes once the 6 times then goes to standbyReplace LOPT
Thomson ICC17
Picture lacking in contrast and brightnessThe symptoms suggested a beam limiter fault, replacing transistor TL02 BF422 which was found to be leaky produced excellent pictures

Assistência TécnicaAs dicas apresentadas destinam-se a técnicos de eletrónica, a tentativa de reparação ou assistência sem ter conhecimentos de eletricidade e eletrónica, podem provocar danos mais graves aos equipamentos e, devido a tensões muito elevadas em alguns circuitos, graves danos fisicos que podem constituir um risco em determinadas reparações.

Não arrisque reparar equipamentos com tensões elevadas se não tiver conhecimentos técnicos para o fazer em segurança.
