My situation is the same as in this post in the archive

It is as if the TV no longer recognises the Beo4 (neither of the two I have), however the 5500 system does respond as usual.
On returning from holiday and switching on the power, the red LED illuminates but does not react in anyway to the remote. Previously it has powered up and requested the pin, but not this time.
I forgot to switch the central heating off, so there were no unusual temperatures involved.
The Beovision3 is standalone with no connections other than to the turntable, and a single SCART to the Toppy.
Any thoughts very welcome.
My BV7_55 does this every now and then - completely unresponsive to volume, stand, sources etc so I can't turn it off! Completely dead to any BEO4 commend. I have to unplug everything at the mains that's connected to it and then plug it in again. This has reset the system without fail on the 3 times it's happened (one of which was this afternoon)
Dave.
Thanks - just tried disconnecting both stand and SCART before switching on. Still left with a stubborn red LED, no response to the BEO4 at all.
"You think we can slap some oak on this thing?"
leosgonewild:Does the led respond to option programming?
I get no response to the BEO4 at all. However that may be because I don't know how to access option programming - can you clarify?
Thanks
Thank you - that is very helpful, the Beovision does respond to Option Programming. 0, 1, 2 all cause the LED to blink. Sadly nothing else happens subsequently, but that is definitely progress!
There is no MasterLink system installed, however I do use the BEO4 to control the 5500 system (which is not connected to the TV directly, only via the Toppy)
Firstly let me say thank you to everyone who has contributed to this thread, especially as I have so little to contribute to this forum in return.
Unfortunately despite following the advice to select V Opt 2, and power down the TV, this morning the same thing happens (or rather doesn't happen). There is no response to any key press, except if I access the V Opt setting, and then the LED blinks once.
If there is anything else I can try please let me know. Many thanks.
We like to try and help!
You haven't said (unless I missed it) which Beovision model you have? This may help with problem solving or maybe give others an opportunity to chip in. Lee from Lifestyle AV may be able to offer some insights as they deal a lot with BV's.
EDIT - just reread it properly and you do say BV3. Not a BV I have.
When you have powered the BV down, have you disconnected the power from the mains or used the standbye switch on the TV?
Thanks Dave - Yes, a BV3-32 type 8813
I have tried both the switch and unplugging from the mains. I have resisted the urge to dismantle anything, so far...
If you disconnect from the mains for more than 30 minutes then reconnect it, you should be asked for a PIN. Have you got the PIN protection activated?
What happens if you press the red dot (off button) on your remote for over 3 seconds?
I wouldn't dismantle anything either! I suppose you could disconnect everything from the BV so it is just stand-alone in case another component is interfering somehow.
Also, double check all connections (especially SCART) are fully connected. A loose SCART can cause havoc - I know from experience.
Sadly I have failed to awaken the TV.
Pressing the remote off for several seconds has no effect, only V.Opt causes the led to blink.
I decided to remove the back and reseat all the connectors that were easy to access, unfortunately this has made no difference. I'm not ready to take it to the tip yet, but I'm running out of options. If anyone has any suggestions at all I'd be very eager to hear them. Many thanks.
A dead microcomputer is not uncommon with the RF models (Avant and BV3), as well as tube problems.
With the following, i am assuming you're experienced enough to do some things inside a tv and are aware of the risks and dangers...
To start with the latter: (tube): remove the little video output PCB from the tube, make sure ir doesn't make any contact with the parts in the tv and try switching it on.
If you see some life (of course no pic but at least the tv comes out of standby), it could well be the tube.
switch off again and re-place the video pcb.
Don't be surprised that, after doing this, the tv turns on again and just works...for as long as it lasts, sometimes one time only.
This is an easy way to establish a tube problem (but reversed: a tube fault does not per se generate this behaviour).
Thanks Paul, much appreciated.
I did as you advised, checked that the LED would blink using V.OPT 2, and then tried to power on, but nothing. No change at all.
Does this point to the micro-computer? Are there any other simple diagnostics I can try?
Ok, so with the video board detached from the tube, no change...
Well, there are other options for trouble, hard to tell from a distance (maybe swap the power supply board, if you can get your hands on a spare), but from 'statistics' i'd at least suspect the computer, or one of the ram/rom chips.
Swapping stuff with a working chassis would be an option, overhere in NL you can get these tv sets for free and/ so i don't know how much time and money you'd be willing to spend on it.
In any case, the 'easy' test are done, i'm afraid (unless someone else knows another option...).
Thanks for all your help.
Unfortunately after 35 years of watching B&O TVs I have thrown in the towel. Ironically my parents 5500 (now relegated to the guest bedroom) still works perfectly, whereas the 7802 died three years ago, and the BV3 died before its 12th birthday (at least it only cost me £150).
It was painfully watching the BV3 being dumped in the tip, almost as painful as it was trying to get it there.
I'm now watching a 42 plasma made by Panasonic, the picture is excellent, the internal speakers are comically poor (not that I ever use them), it cost just £180 new.
