The PAL/Secam/NTSC Decoder and RGBdriver board: This is the RGB Board. http://img146.imageshack.us/img146/1037/p1170001pu6.jpg Typical defects: heat problems. The picture is not clear, there are distortions or lines Replace all electrolyt caps. The picture flashes in green or red during power up, strong colour distortions, green or red lines There seems

The mainboard: Rear view: http://img182.imageshack.us/img182/9606/p1170015fp5.jpg Front view: http://img186.imageshack.us/img186/8353/p1170016ki4.jpg The big black metal sheet is a frame and a cooler at the same time. From left to right you see 4 chips mounted on this frame: 2x TDA 2040 chips for the sound amplifier, a 11-pin Chip for the deflection

The power supply: The power supply can be set to a service position, press the hook on the top and a pull a second one on the black metal sheet in the front. The plastic is old and very hard. Watch out, these hooks can break easily. But the frames are still available, around 20 Euros each ;) http://img178.imageshack.us/img178/5791/p1120009qe3.jpg Put

How to dismantle the MX5500: WARNING: in this tv are voltages up to 27KiloVolts, 27.000 Volt. If you hit the red cable or the picture tube while the tv is still under operation, then you will be injured or dead. This is really no fun! The power supply runs with around 350V and very high power, if you hit here the wrong part, there can be very high currents

Hello B&O fans, this is a little guide how to test and repair this magnificent MX3500 MX5500 LX5500TV set. I think, it was besides the newer MX6000/7000 and the last MX8000 the most advanced and highest evolution of all video TV sets on the market. Almost 20 years old, a MX5500 has a crystal clear picture, very good sound and is still better than

Nein, man kann beide Pentas modifizieren. Bei beiden Typen (also BeoVox und BeoLab) kann man die Frequenzweichen verbessern, bei der BeoLab nochmals den Verstärker zusätzlich. Ein zerlempertes Paar Beovox liegt so etwa um 500 Euro, zerkratzt und verbeult. Schlimme auch noch deutlich drunter... Ein technisch und optisch wie neues Päärchen

Something like that is good enough. It should be capsuled and resist against dust and smoke. http://www.reichelt.de/?;ACTION=3;LA=2;GROUP=B212;GROUPID=3127;ARTICLE=14619;START=0;SORT=artnr;OFFSET=16;SID=278upq4awQARsAABt7JDQ958145b8daefb9aac00d2d0973afc559

The broken sound and wrong speed: Sometimes a small part in the deck gets lost, it is a very small steel bolt. The white plastic part and the bolt are one part, it is still available at B&O, the part number is 3016023 Guide pol control, costs around 5 Euro. The plastic part breaks around the bolt, there is almost every time a split in the material

The defect tension arm: Sometimes a small spring gets lost, it's the one on the right side. Without this spring the "tension arm" will be in the wrong position, the tape is kept loaded on the tension arm and will be destroyed when ejected... or some other parts. I have simulated this defect here, you see the two guides for the tape around

Broken time and adjustments: A defect lithium cell is sometimes very difficult to see. Sometimes the VX works quite normal, the picture is good, but if you disconnect mains, then the logon (tv set and VX are talking when connected by scart, the tv makes a download of channel data to the VX) is very slow. Sometimes the VX disappears from the AV-menu
