EN 6 • 2. L03.1U AA Safety Instructions, Warnings, and Notes For sets produced before 1.1.2005, containing leaded soldering tin and components, all needed spare parts will be available till the end of the service period. For the repair of such sets nothing changes. In case of doubt whether the board is lead-free or not (or with mixed technologies), you can use the following method: • Always use the highest temperature to solder, when using SAC305 (see also instructions below).

ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available. When ComPair is installed together with the Force/SearchMan electronic manual of the defective chassis, schematics and PWBs are only a mouse click away.
EN 12 • 5. L03.1U AA Service Modes, Error Codes, and Fault Finding Set turns on, but without picture and sound. The screen shows snow, but OSD and other menus are okay. Blinking LED procedure indicates error 11, so problem is expected in the tuner (pos. 1000). Check presence of supply voltages. As “Vlotaux+5V” at pin 5 and 7 are okay, “VT_supply” at pin 9 is missing. Conclusion: resistors 3449 & 3450 are defective.
