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.
2. PURITY ADJUSTMENT
No. 1
Adjustment point PURITY ADJ.
Adjustment procedure/conditions 1. Receive the GREEN-ONLY signal. Adjust the beam current to ~700 µA . 2. Degauss the CRT enough with the degausing coil. Note: Follow the Job Instruction Sheet to adjust the magnetic field. Vertical Bv: +0.030 mT (0.30 gauss) Horizontal Bh: +0.020 mT (0.20 gauss) (Reference: page 3-6) Maintain the purity magnet at the zero magnetic field and keep the static convergence roughly adjusted. Observe the points a, b,as shown in Fig. 1-1 through the microscope. Adjust the landings to A rank requirement. Orient the raster rotation to 0 eastward. Tighten up the deflection coil screws. Tightening torque: 108 ± 20 N (11 ± 2 kgf) Make sure the CRT corners landing meet the A rank requirements. If not, stick the magnet sheet to correct it. Note: This adjustment must be done after warming up the unit for 30 minutes or longer with a beam current over 700 µA. Note: Set to service mode by remote controller then press factory process R/C RGB key to change to RGB mono colour mode. For the following colours press R/C RGB(Hex 7E) key to change.
