Good pdf of the service manual for this unit. Includes disassembly instructions, full schematics, board layouts, parts lists and diagnostic information. Some information is in the pdf twice (single pages, and split pages), but that could be how it was originally generated by panasonic, or perhaps the idea is to make it eaiser to put onto 8.5 x 11" pages.
Information was exactly what I needed. Delivery was overnight (less than 12 hours) and I was happy with the process.

Perfect like it was descriped, Perfect like it was descriped
;
Very good detail, all pages clear, exactly what I needed
;
Excellent service, and just what I needed to service my TU-7700. All pages of the manual are clear and easily readable.
;
Excellent printing quality.
A complete and very usefull service manual with all details.
GREAT SERVICE AT VERY LOW PRICE!

We received the manual in a timely manner and it was exactly what we were expecting. Excellent replacement for original Service Manual.
All schematics are very legible. We are really satisfied.
3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
1.1.1. Leakage current cold check
1. Unplug the AC cord and connect a jumper between the two prongs on the plug. 2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to thechassis, the reading should be between 1M and 5.2M . / When the exposed metal does not have a return path to the chassis, the reading must be .

1.1.2. Leakage current hot check / (See Figure 1 .)
1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5k , 10 watts resistor, in parallel with a 0.15 F capacitors, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1 . 3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor. 4. Check each exposed metallic part, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet and repeat each of the above measurements. 6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent) may be used to make the hot checks, leakage current must not exceed 1/2
