Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++

Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you

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.

< TUNER SECTION > <U, LH>
1. Clock Frequency Check Settings : � Test point : TP2 (CLK) Method : Set to AM 1710kHz and check that the test point is 2160kHz ± 45Hz. 2. AM VT Check Settings : � Test point : TP1 (VT) Method : Set to AM 1710kHz and check that the test point is less than 8.5V. Then set to AM 530kHz and check that the test point is more than 0.6V. 3. AM Tracking Adjustment Settings : � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : L951 (1/3) Method : Set to AM 1000kHz and adjust L951 (1/3) so that the test point becomes maximum. 4. AM IF Adjustment Settings : � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : L802 ........................... 450kHz 5. FM VT Adjustment. Settings : � Test point : TP1 (VT) � Adjustment location : L906 Method : Set to FM 108.0MHz and adjust L906 so that the test point bcomes 7.0V ± 0.1V. Then set to FM 87.5MHz and check that the test point is more than 0.4V. 6. FM Tracking Adjustment Settings : � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : L903 Method : Set to FM 87.5MHz and adjust L903 so that the test point is less than 9dBµV. 7. DC Balance / Mono Distortion Adjustment Settings : � Test point : TP3, TP4 (DC balance) TP8 (Lch), TP9 (Rch) (Mono Distortion) � Adjustment location : L801 � Input level : 60dBµV Method : Set to FM 98.0MHz and adjust L801 so that the distortion is less than 1.2%. Then check the voltage between TP3 and TP4 is 0V ± 500mV. 8. Output Level Check <AM> Settings : � Test point : TP8 (Lch), TP9 (Rch) � Input level : 74dBµV Method : Set to AM 1000kHz and check that the test point is 40mV ± 3dB. <FM> Settings : � Test point : TP8 (Lch), TP9 (Rch) � Input level : 60dBµV Method : Set to FM 98.0MHz and check that the test point is 200mV ± 3dB. 9.
