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.
FLOW CHART NO.12 EV+3.3V is not outputted. Is 5V voltage supplied to the collector of Q1159? Yes Is the voltage of approximately 4V supplied to the base of Q1159? Yes Replace Q1159. No No Check D1108, L1105, C1120 and their periphery, and service it if defective. Check IC1153 and their periphery, and service it if defective.
FLOW CHART NO.13 P-ON+2.5V is not outputted. Is 4V voltage supplied to Pin(1) of IC1151? Yes Replace IC1151. No Check D1105, C1110 and their periphery, and service it if defective.
FLOW CHART NO.14 P-ON+3.3V is not outputted. Is 5V voltage supplied to Pin(1) of IC1152? Yes Replace IC1152. No Check D1108, L1101, C1114, C1116 and their periphery, and service it if defective.
FLOW CHART NO.15 The fluorescent display tube does not light up. No Is 3.3V voltage supplied to Pin(6, 24) of IC1503? Yes Is approximately -24V to -28V voltage supplied to Pin(15) of IC1503? Yes Is there approximately 500kHz oscillation to Pin(26) of IC1503? Yes Are the filament voltage applied between (1) and (24) of the fluorescent display tube? Also negative voltage applied between these pins and GND? Yes Replace the fluorescent display tube. No Check the -FL line and service it if defective. No Check the EV+3.3V line and service it if defective.
Check R1560, IC1503 and their periphery, and service it if defective. Check the power circuit, D1101, D1112, C1106 and their periphery, and service it if defective.
