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.

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.

4.1.1.
FACSIMILE SECTION (for KX-FP80)
THERMAL HEAD
Please replace original Service Manual page 138 in the KX-FP80. (6.4.3.THERMAL HEAD) 2.Circuit Operation Refer to the block diagram and the timing chart on the following page. There are 9 driver ICs aligned horizontally on the thermal head and each one of these ICs can drive 192 heat-emitting registers. This means that one line is at a density of 192�9=1728 dots=(8 dots/mm). White/Black (white=0, black=1) data in one line increment is synchronized at IC501 pin 115 (THCLK), and sent from IC501 pin 114 (THDAT) to the shift register of the ICs. The shift registers of the 9 ICs are connected in series, and upon the shift of the 1728 dot increment, the shift register becomes filled with data, and a latch pulse is emitted to each IC from IC501 pin 118 (THLAT). With this latch pulse, all the contents of the shift registers are latched to the latch registers. Thereafter, through the addition of strobes from the IC501 pins (105, 106), only the dot location of black (=1) among latched data activates the driver, and the current passes to heat the emitting body to cause heat emission. Here, the two line strobes, STB1 to STB2, impress at intervals of 9.216 msec, as required for one-line printout. The sequence is shown on the next page. [Moreover, for the strobe width, the thermistor value inside the thermal head is detected according to IC501 pin 2. Depending on that value, the strobe width is recorded in ROM (IC502). Accordingly, the strobe width is determined.] When the thermal head is not used, the IC501 (23, THON) becomes low , Q501 turns OFF, IC506 turns OFF, and the +24V power supply for the thermal head driver is not impressed to protect the IC.
