This manual is accurate and of high quality. It is only volume 2 of the service manual. This is schematic, parts lists, and exploded mechanical drawings. The theory of operation and the diss-assembly instructions are in volume 1. The unit can be tricky to dis-assemble portions of so the volume 1 manual can be important. The product description of the manual is accurate but it does not say anything about volume 1 and the image of the front page does clearly say Volume 2.

Wellll again thank you very much fast and effective. Clear and well done for such an old TV!!!!

It has all the information you will need to fix it. The main circuit diagram is only A4 but being a PDF, you can print it to any size - I did it on two sheets of A3 and it didnt lose any detail - just made it readable when pinned up above the bench. I've found the fault, just need to buy some obscure bits to get it going again!
I cant fault the process, I paid for the manual in the morning and it was ready to download by lunch time.

Very good copy in a 54 pages PDF archive. This is my sixth purchase here. :)

Another excellent buy! File too clear and explanatory.
5-8 Output Power of Magnetron
CAUTION MICROWAVE RADIATION
PERSONNEL SHOULD NOT ALLOW EXPOSURE TO MICROWAVE RADIATION FROM MICROWAVE GENERATOR OR OTHER PARTS CONDUCTING MICROWAVE ENERGY. The output power of the magnetron can be measured by performing a water temperature rise test. Equipment needed : * Two 1-liter cylindrical borosilicate glass vessel (Outside diameter 190 mm) * One glass thermometer with mercury column NOTE: Check line voltage under load. Low voltage will lower the magnetron output. Make all temperature and time tests with accurate equipment. 1. Fill the one liter glass vessel with water. 2. Stir water in glass vessel with thermometer, and record glass vessel�s temperature ("T1", 10±1° C). 3. After moving the water into another glass vessel, place it in the center of the cooking tray. Set the oven to high power and operate for 55seconds exactly. (3 seconds included as a holding time of magnetron oscillation:) 4. When heating is finished, stir the water again with the thermometer and measure the temperature ("T2"). 5. Subtract T1 from T2. This will give you the water temperature rise. ( T) 6. The output power is obtained by the following formula; Output Power = 4.187 x 1000 x 52 T+0.55xMcx(T2 -T0) 55 : Heating Time (sec) 4.187 : Coefficient for Water 1000 : Water (cc) T : Temperature Rise (T1-T2) To : Room Temperature Mc : Cylindrical borosilicate glass weight
7. Normal temperature rise for this model is 9.3° C to 10.5°C at 'HIGH'. NOTE 1: Variations or errors in the test procedure will cause a variance in the temperature rise. Additional power test should be made if temperature rise is marginal.
