For this Dick Smith TV GE6878 (Thompson) I replaced the broken remote with a universal it kinda works though if its more than a few meters away sometimes the buttons register and sometimes they wont so I bought another remote from another brand and it has the same problem, I've had an old TV in the past that the sensor died completely and I replaced it to fix it could this be a similar problem? I tried looking for a service manual, spare parts for a receiver and a parts list but I couldnt find any info. can someone please help me to find the info online for a service manual or where I can buy a receiver board, I havnt taken the TV apart yet to inspect if the receiver board has a dry solder joint or dying capacitor. Thank you.

Stick an oscilloscope on the IR receiver on the TV and verify the range of the remote. I've seen instances of this from bad batteries in the remote (even they still measured 1.5V each, but couldn't handle the current draw from thee remote) to bad capacitor on the IR board and over to dirt on the IR.
