Service Manual for Daewoo dct7474 paex0025-N existing??

[Bard]

Hi all.

I got a Pureflat Daewoo 74cm TV as a present. After 4 years, the picture dissapears with strippes but you are hearing all audio correctly and the visual is barely visible. It started with if it is on for about 5 minutes, it will show all OK but after that 5 minutes, it will show the stripe effect. I have checked for dry joints, and even soldered all contacts just in case. It did not work, so some component must have gone faulty. Even after my attempts, it did after another few days started to show the stripes as soon as you switch it on.

I would like to know if there are a manual for this television set.
At the back of the TV is says Model DCT7474 and on the chassis board and the small PCB behind the tube has the number PAEX0025-N on it.

I have however seen exaclty the same TV sold as a different brand called AIM.

Can anyone maybe point me in the right direction please?
