Okay thank you for confirming.
Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, most likely a faulty power supply or main/control board, though there are many possible failure points. This issue could be a manufacturing defect, but is also often caused by a power event (shock/surge, prolonged over/under voltage condition, etc).
This could also be the result of age related wear and tear, as a 2001 model tv, that type of failure wouldn’t be surprising. Even for a CRT based set, it is about 50% past its expected service life.
There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation
1) Unplug the power cord from the tv
2) Wait at least 1 hour (60+ Minutes)
3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.
If this reset process does not work, it would unfortunately confirm an internal hardware failure.
This is something that would require repairs to correct; if you're thinking about a do it yourself repair, you'll need to be comfortable and skilled with electronics repairs, which would require dismantling the set (removing the back panel of the tv), diagnostics with a digital multimeter to test voltages inside, changing out boards as needed, and possibly desoldering/removing and soldering/replacing capacitors (a common failure point).
If you’re considering repair at a local shop, you’ll find a typical repair to be around $400-500 for diagnostics, parts, and labor.
While I understand that this tv was very expensive and state of the art when new, that is no longer the case. B&O tvs are nearly impossible to find parts for and it is equally difficult to find anyone who works on CRT tvs at all anymore, let alone the specialty BO products which require special training. For a set of this size and age, you would be much better off replacing it rather than repairing it. You can get a brand new LED tv
with a fresh warranty and better picture in the $200 range, less than half of what you could expect to pay for repairs.
Depending how you’d like to proceed here, I can help with finding parts, finding a repair shop, or recommending replacement options. Just let me know.
