Careless handling · Use only lead-free soldering tin. If lead-free solder paste is during repair can reduce life drastically. Make sure that, required, please contact the manufacturer of your soldering during repair, you are connected with the same potential as equipment. In general, use of solder paste within the mass of the set by a wristband with resistance. Keep workshops should be avoided because paste is not easy to components and tools also at this same potential. store and to handle. · Be careful during measurements in the high voltage · Use only adequate solder tools applicable for lead-free section. soldering tin. The solder tool must be able: · Never replace modules or other components while the unit To reach a solder-tip temperature of at least 400°C. is switched "on".

Ensure that a stable situation is created to perform measurements and alignments. When using foam bars take care that these always support the cabinet and never only the display. Caution: Failure to follow these guidelines can seriously damage the display! Ensure that ESD safe measures are taken.4.3 Assembly/Panel Removal 32"4.3.1 Rear Cover Warning: Disconnect the mains power cord before removing the rear cover. 1. Remove the fixation screws that secure the rear cover. 2. Lift the rear cover from the TV. Make sure that wires and flat foils are not damaged while lifting the rear cover from the set.4.3.2 Small Signal Board (SSB) Caution: it is mandatory to remount all different screws at their original position during re-assembly. Failure to do so may result in damaging the SSB. 1. Release the clips from both the LVDS Flat Foil connectors. Caution: be careful, as these are very fragile connectors! Take the flat foils out of their connectors. 2. Unplug all other connectors. 3. Release the tape near the bottom side of the set from the LCD panel. 4. Remove all other fixation screws from the SSB. 5. Take out the SSB together with its shielding. 6. Remove the screws near the HDMI and L/R audio connectors. 7.
