Just to close the loop on this, it appears the problem was with a melting adhesive that is used on the inside of the TV. There is a parchment paper that separates one of the PCBs from shorting on the metal DVD player. This piece of paper is fixed to the PCB with a double sided adhesive tape. This tape had become very gummy, almost like a liquid and had turned a nasty shade of brown. I cleaned all of this adhesive off with isopropyl alcohol, removed as much as possible, then attached a new piece of paper to the inside of the PCB with some new double sided tape made for electronics. The TV now works. Thanks to everyone who read this and provided assistance!

The shield is actually really difficult to remove but, instead, I used some tiny probes and my multimeter to probe the IR RX pin on the ribbon cable connector on PCB58. It reads 5V when idle and then when I use my Beo4 remote to issue the “Go” command, it quickly drops to 4.6V. I’m guessing that means the IR sensor actually is working and maybe the fault is higher up the chain. The search continues. Any other advice from anyone would be greatly appreciated.

Thank you so much for responding and telling me about this. I had thought about removing the metal shield but I will go ahead and do that (after I try checking that it hasn’t somehow switched to option 0). If it is the capacitors under the shield, I am guessing those would be surface mounted components since the back of the PCB has no through-holes in that section?

Thanks again. This is my only B&O product so it really helps to hear from someone with more experience. I tried getting help from the CRT TV enthusiast community but it seems that B&O TVs are such a different kind of product that the regular CRT TV enthusiast community can’t really offer much help for issues like this. Thanks again!
