I recently purchased a manual for a Samsung DLP tv to help with a trouble shooting problem I was having. Every tv repair shop wanted close to $400.00 for the fix, but after I found Owner-Manuals.com I hit pay dirt. The manual they had for me to purchase and download was a complete service manual for the exact tv I needed. It was complete with wiring diagrams, schematics, and even part numbers. If your the fix it yourself type I highly recommend trying to find any manual here before paying someone else to fix whatever problem your having.
This service manual have great value... Recommended A+++++++

Board- Setting-up (Non-UK version) The only adjustment necessary on the RGB board is the setting-up of the Phase Locked Loop (PLL), a circuit which mutes the audio output in the absence of a valid video signal (i.e. no TV or AV).
Make sure there are no syncs applied to the input of the phase locked loop. This can be acheived by tuning the receiver to an unused channel (ie noise). Monitor II02 pin 5 with a frequency counter set to read kHz to 2 decimal places. First turn RI22 fully clockwise, then turn anti-clockwise to set the frequency between 15.45 kHz and 15.59 kHz, nominally 15.52 kHz. Check MI01 pin 6 is low (0~). Tune the receiver to a valid signal. Check that syncs are applied to the input of the P.L.L. Check that MI01 pin 6 is high (SV).
