I am very happy regarding the online purchase of this manual from Owner-Manuals.com as with this I could set right my Denon CD player and Amplifier.
I once again sincerely thank them for the prompt service which was rendered to me.

More than pleased with my prurchase, very good product for the price.

Manual-link came 30 minutes after having paid for an extremely rare (40 years old) item (sony icr-120) and helped me to get the radio rework again. So really good help for me, fast and reliable delivery and -taken that into consideration- a very reasonable price for that service. So thanks again! Mike, Germany

Some of the pictures in this manual are a bit irritating. I had to dissassemble the unit and some of the screws have different threads, which is not mentioned in this manual. Also some of the drawings of the boards look different than the actual boards.
After all, the manual was very useful. I was able to recalibrate the capstan drive and it is working fine again.

This manual is very good. 303 pages scanned in a very high resolution. My camera has bad, leaking capacitors which all of the V5000 models are suffering from these days.
There is a huge part list with all capacitors, transistors etc. in this manual which helped me a lot. Otherwise I would not have been able to buy replacement parts.
The dissassembly guide is very enormous and detailed. Unlike on the Panasonic MS1 manual I downloaded here it actually looks like the real parts look. And the screws are labeled correctly, so you shouldn't have any left after the repair. ;)

ADJUSTMENT
X86 Circuit Adjustment Specification (K, R, H type)
Item 1. Adjusting image detection coil L103 Adjustment Method & Value 1. Turn VR101 [RF-AGC] counter-clockwise as much as possible. 2. Impresss sDC2.0V to TP [IF AGC] (IC101 #36). 3. Input fo=45.75MHz Mod=1KHz AM60% Level=100dBµ to TP [IF] (CF1 #1). 4. Observe the waveform of TP [VIDEO] (IC101 #8) using an oscilloscope, and adjust L103 so that the output level is at the maximum.
Maximu
Condition � ANT no signal � If the waveform is clipped, raise the DC voltage somewhat. � AC range
2. Adjusting audio detection coil L101
1. Turn VR101 [RF-AGC] counter-clockwise as much as possible. 2. Input fo=41.25MHz non-modulated Level=94dBµ to TP [IF] (CF1 #1). 3. Connect a voltmeter to TP [SIF] (both ends of R107) and adjust L101 to 0V ± 0.01V. 1. Turn VR101 [RF-AGC] to clock-wide direction as much as possible. 2. Input RF signal 30dBµ 11CH color bar to ANT input terminal. 3. Audio (P/S-6dB) non-modulated. 4. Connect a voltmeter to TP [IC101 #12] and adjustVR102 [SMET] to 3.5V ± 0.05V. 5. Set RF signal 70dBµ and adjust VR101 [RF-AGC] so that the value of the voltmeter connected to TP [IC101 #12] is 4.6V ± 0.05V. 1. Connect frequency counter to PIN1 of CN5 [IC2 #7]. 2. Connect Pin3 [IC2 #8] of CN5 and Pin2 [GND]. 3. Adjust VR1 [15KHz] and set to 15734Hz ± 100Hz.
� ANT no signal
3. Adjusting S-METER VR102 4. Adjusting RF AGC VR101
� SlideVR101 so that AGC will not be effective at 30dBµ. � Be sure to conduct adjustment on the SMETER before adjusting RFAGC.
5. Diversity free-run frequency VR1
� ANT no signal
