Re: reward for anyone one who fixes this bang and olfsen
It has a Samsung 720p 40" panel from about 2006 in it. I am quite surprised it is worth as much as you claim; must keep an eye out myself!Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I every one!!
I have a Bang & Olufsen Beovision Horizon that is always in standby mode ( green light on ).
Main board is 715g7132-m0h-000-005k. Corrupted firmware? I have all the ok voltages in psu.
Any idea?
Thank's...

Hi.
BacCaps forum is awesome - thank YOU ALL for sharing knowledge!
This is about DONG YANG PSU BN44-00195A failiure in Samsung 245BPLUS. It started with bang and smoke from the back of LCD. Downloaded diagram BM44-00192A - a bit different but I will use all parts names from this diagram [and real PSU].
BIG CAP CP801 had 315V, on standby pin 5,2V. After shorting S_B ON (through 3,3k ohm resistor) 24V and 5,3V were missing, on CP801 was 312V.
RM801 [real PSU: RM801 - 0,22 ohm 1W] - FAIL
burned, measured 10M ohm.
QM801 [real PSU:... -
I'm about to take a journey into repairing this 3 Channel ICE amp. It's got a bunch of fun components I am not familiar with like Direct Stream Digital chips. It also has some onboard Digital Signal Processor which I haven't identified yet.
I am not familiar with ICE amp circuits other than they are a type of PWM amplifier so I'm assuming they require a ton of high frequency filtering on the output. I'm also assuming that the output of the DSD chips probably directly feed the ICE amp signal since DSD is also essentially PWM or creating an averaged AC signal using high frequency ~2MHz... -
Hi guys
I have a B&O Omen laptop here. It has very specific fault symptoms, hopefully someone can give me some guidance
If I plug in a known good 180W third party charger the little LED next to the power jack on the laptop flashes red once, but the laptop will not start. It will not flash red again unless you unplug and reconnect the power.
If I remove the main battery (I can't see a cmos battery) then the led by the jack does not flash when I plug in the adapter, but if I press the power on button with adapter attached it flashes once white every time... -
greetings from Westport CT.
I have recently purchased a circa 1986 beosystem 3300.
it worked gloriously for a few hours. then no sound and smell of burnt electronics from the beomaster 3300 amp model: 2953
attached is a bit of the schematic, I have the full pdf schematic if needed.
all, functions aside from sound output seem to still work on the unit. (cd/tape/phono change, display volume display, remote control, radio station, on off etc.
I'm pretty sure the smell was from resistor edit[r122] burning up. (see picture)
I will replace the...
