Service Manual for GRUNDIG T-55 370/5
CUC is 'Compact Universal Chassis', it's the chassis number of the set, it's on the back near the model number, it should be CUC followed by four digits.Night Rider said:i have this tv model and it doesn't work for a few months. it's my grandfather's tv. i'm new on tv repairment and i study on it. so, i said that it is a reason to make my first steps knowing of course about the dangers. So, i asked if i can find just easy a service book for this model to start my "experiments". If you can help me i can find the CUC number when i'll go to the village, because i supposed that the tv model was enough. what is the CUC number Nigel? C.... U.... C..... ?
CUC7301 is the number I need.Night Rider said:Sorry Nigel, the model is: T-55 730/5 and
the CUC is: 7301
I find and another number, i don't known if it is useful to you, here is:
C669 is a capacitor, it's close to the switch-mode mains TX, and it's almost certainly blue.Night Rider said:Yes it's dead. I want to measure the PSU but first i want to ask you first. Is there any service manual to attach me, because i want to known where i will measure. if you are sure about this problem show me only the PSU circuit with some voltages so i can know what i'm doing. C669 is a capacitor or something else? Don't laugh, i don't known very well about the numbers of some special tv components. As i remember this tv had another problem at the past and fixed by a technician, but after a month the tv was dead. The power led is off when i turn on the tv.
Thanks for helping me.
