Manual was reasonably easy to follow. I am not an engineer or know much about electronics but with the manuals help I was able to figure out the problem, identify the part required for the repair. Replacement part cost around $30. Whilst replacing the part I was telling myself, "this aint gonna work cos it seems far too easy". Took about 15 minutes to do and my plasma TV works a treat. Would never have been able to do this without the service manual.

It is OK, this manual help me to repair my dynacord

Good manual. Even it is an old printed manual, it is well scanned and complete, with all drawings, schematics and parts list. Very good return for the cost.

I'm very satisfied with my purchase. It resolved my problem. Owner-manuals.com is a very very good place.
Thank you!

1.3.8 Coefficient display of adjustment results
For some of the adjustments (FE and RF offset, FZD cancel, F and T gains, and RFAGC), the adjustment results can be displayed and confirmed in the test mode. The coefficient display in each auto adjustment is as follows: 1) FE and RF offset Reference value = 32 (coefficient of 32 indicates that no adjustment is required) The value is displayed in the unit of approximately 32 mV. Ex. When the FE offset coefficient is 35, 35 - 32 = 3 x 32 mV = 96 mV The correction is about +96 mV, which means the FE offset before adjustment is - 96 mV. 2) F and T gain adjustment Reference value for focus and tracking = 20

A
The displayed coefficient / the reference value indicates the adjusted gain. Ex. When the AGC coefficient is 40, adjustment of 40 / 20 = 2 times (+ 6 dB) has been performed. (It means that the original loop gain was half the target, and the whole gain was doubled to obtain the target value.) 3) RF level adjustment (RFAGC) Reference value = 8 The coefficient of 9 to 15 indicates to increase the RF level (for more gains). The coefficient of 7 to 10 indicates to decrease the RF level
C
(for less gains). When the coefficient changes by 1, the gain changes by 0.7 to 1 dB. When the coefficient is 15, the gain is the maximum at TYP + 7.9 dB. When the coefficient is 0, the gain is the minimum at TYP - 4.6 dB.
