Very fast and perfect delivery. Clear and well scanned. A lot of work professionally realized.
Again thak you a lot

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. :)

3. TEST MODE
3-1 SETTING
Turn the power ON while pressing the [BAND] key.
� During the test mode, it can be operated in a special manner that is deferent from an ordinary operation by using the keys on the remote control or the main body ,specifically as shown in the following table (3-5 CONTENTS). � Channel space will be no changed in the test mode.
3-2 CANCELLATION
Unplug the AC power cord from an AC power wall outlet.
3-3 STARTING ACTIVE CONTENTS
� The power on state is entered whenever the power is trued on while pressing the [BAND] key. � All functions are initialized and activated in the all lighting mode. � All lighting mode is canceled when any main unit's keys are pressed. The normal display obtained when the selector is set to TUNER then appears. � E2PROM check(Etype only). Check the reading data and the writing data of the E2PROM after setting the test mode. Display shows blank if the reading data and writing data are the same. Display shows "LW" if the different data will be written to E2PROM.
3-5 CONTENTS
3-5-1 TUNER FUNCTION WITH THE SELECTOR ON TUNER (E TYPE ONLY)
OPERATION KEY FUNCTION PTY DISPLAY TA/NEWS S LEVEL RF ATT FL DISPLAY REMARKS

3-4 ACTIVE CONTENTS
� The mute control is not activated when the mode is switched. � The test mode will be terminated by plugging it off the power source or by initializing it when all the settings will be initialized.
3-5-2 AMP FUNCTION WITH THE SELECTOR ON SOMETHING OTHER THAN TUNER � One touch max,min setting for Audio level. SOUND KEY KEY MASTER VR. BASS TREBLE BAND AUTO MEMORY -89dB 0dB -10dB 0dB 0dB 0dB +10dB +10dB +10dB
