If you can find that PCB/chassis version number and I happen to have the diagram then I will post it up for you.
I'll have a look next week, when i'm next round, and i'll note down any codes/numbers I see, which could possibly help

Thank you for your help!

The bar code is of no use to me, as that will be Durabrands specific number which I definitely won't have access to
It is the actual Chassis/PCB number I need, it will be marked on the board and not a label.
If I can find a suitable PCB layout drawing I may be able to show you the location where to find it.
There is no guarantee that I have the actual specific circuit as it is likely custom built for Durabrand, however I will look for you.

I forgot about the ..TA.... numbers indeed. That number is probably the most useful even if it may not point to the exact variant depending on the stuffing of the board. You will get something close anyway.

The longish barcode on the back should carry the exact official chassis variant though (if the label was applied by Profilo Telra themselves), but wouldn't be as useful probably for looking things up.

I'll have a look on Wednesday, when im back round there, and i'll report back, I'll keep an eye out for a TA number for sure, and anything else that might help.

I really appreciate your help, thank you!

Thanks

Hi,

With the TV now. Iíve found the TA number which is 03TA056A and it might have PT90 and PT92 chassis parts. (See attached)

(The PT90 is on the CRT PCB and the PT92 is on a composite in PCB. Im not to sure on the main PCB but there is a plastic bracket on the LOPT which holds the back on with PT90 moulded in)

The resistor is definitely RP71

Thanks for your help.
