- Very good scan quality, PERFECT!
- Sehr gute scan Qualitaet, empfehlenswert!
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.

Dot matrix LCD driver power supply. LCD driver power supply. Internal logic power supply. Input/output singnal synchronization. When "L", a forced LCD OFF operation is performed, and SIGn & COMn output the unselected waveform. Initial state is set when "L". "H" if there is KEY data, "L" if there is none. KEY data can be read in respective of the state of this pin, CMOS output. DATA shift clock. DATA is read on rising edge, and output on falling edge. Performs input of commands, key data etc., and key data output. Input is performed from the MSB on the rise of the shift clock, and the first 8 bits are recognized as a

Dot matrix LCD common output. 1. Dolby NR Adjustment Settings : â¢ Test tape : TTAâ200 â¢ Test points : TP1(Lch), TP2(Rch) â¢ Adjustment location : SFR201(Lch), SFR202(Rch) Method : 1. Play a Dolby NR tape and adjust SFR201 and SFR202 so that the Lch (TP1) and Rch(TP2) levels are 300 Â± 5mV. 2. Adjust the level in the forward running direction, and then check in the reverse direction. If the level drifts from the specification, perform readjustment.
