Well I never thought I'd need to replace the remote before the TV itself.
It's been a good tele from COTD bought years ago and still going strong.
Model Daijitsu (Samsui) LCD42HWA
I found a few websites that sell smart remotes that you press "set" until the TV reacts and then it's ready to take control of the TV.
No guarantee it will work on my model but can be returned. Approx $25 through PayPal.. I've sent a message with the model number asking if it will work with my TV.
Anyone aware of a reliable source for this particular TV ?

Your TV is compatible with harmony remotes… And they are very good devices.
