Wellll again thank you very much fast and effective. Clear and well done for such an old TV!!!!
;
It has all the information you will need to fix it. The main circuit diagram is only A4 but being a PDF, you can print it to any size - I did it on two sheets of A3 and it didnt lose any detail - just made it readable when pinned up above the bench. I've found the fault, just need to buy some obscure bits to get it going again!
I cant fault the process, I paid for the manual in the morning and it was ready to download by lunch time.

Very good copy in a 54 pages PDF archive. This is my sixth purchase here. :)

Another excellent buy! File too clear and explanatory.

A manual hard to find. It was very helpful to restore my device.
