Veramente completo, dettagliato e perfetto nella visione. Perfect, thanks!
 ;
Fully functional usable service manual. Considering the age of the manual and device quality was better than expected

Thank you very much, I've been very happy to find this manual on "Owner Manual". It's a perfect copy and it has been really useful for my work!

It took about 24-hours after my payment before I was able to get to the download. Apparently, payment processing is not 100% automated. That is no big deal, just be aware of that going in.
After I got to it, it was in good shape, easy to read, etc. Not some cheap FAX copy looking thing.
Also, this site was the cheapest I found. Another Plus!

Good price, very legible manual, exactly what I needed -- but had to wait a day to actually get the download of the manual. Would have preferred to download it immediately after payment rather than waiting for someone to "process" my order. I was surprised that I had to wait that long.
KTC-V500E/N/P
ADJUSTMENT
X25 Circuit Adjustment Specification (M : For the Other Markets) Item
1. Video detection co il adjustment L303
Adjustment method/Adjustment value
1. Turn VR301 [RF-AGC] fully to the right. 2. Apply DC2.0V to TP [IF AGC] (IC300 pin36). 3. Feed fo=38.0MHz, Mod=1kHz, AM60%, Level=100dBµ into TP [IF] (A100 pin8). 4. Observe the TP [VIDEO] (IC300 pin8) waveform on an oscilloscope and adjust L303 for maximum level.
Conditions
No ANT signal If the waveform is clipped, slightly increase the DC voltage. AC range
Maximum
2. Audio detection coil adjustment L300
1. Turn VR301 [RF-AGC] fully to the right. 2. Feed fo=31.5MHz, No Modulation, Level=94dBµ into TP [IF] (A100 pin8). 3. Connect a voltmeter to TP [SIF] (both ends of R314) and adjust L300 for 0V ± 0.01V.
No ANT signal
3. S-METER adjustment VR300 4. RF AGC adjustment VR301
1. Turn VR301 [RF-AGC] fully to the right. 2. Feed a 30dBµ CHINA 9CH color bar RF signal into the ANT input terminal. 3. Audio (P/S ratio -6dB) no modulation. 4. Connect a voltmeter to CN300 and adjust VR300 [SMET] so it reads 3.5V ± 0.05V. 5. Set the RF signal to 70dBµ and adjust VR301 [RF-AGC] so that the voltmeter connected to CN300 reads 4.8V ± 0.05V.
Postpone adjusting VR301 to prevent AGC having effect at 30dBµ. Ensure the RF AGC adjustment is performed after the S-METER adjustment. No ANT signal Test mode
5. Diversity free run frequency adjustment VR400
1. Connect a frequency counter to CN400. 2. Using the remote control unit TV/NAVI button, switch to adjustment mode. 3. Adjust VR400 [15kHz] so as to obtain 15625 ± 100Hz.
