Reason : During reception of a DK transmitter in band 1 and 2 the software doesn’t switch in the stereo decoder MSP3415D to DK . The DK sound (6.5MHz) is missing.

TDA9605H audio proc chip - 9v supply was low & F1509 100mA fuse failed due to chip drawing excess current

Phenomenon mostly occurs in case of high environment temperatures. Mount an electrolytic capacitor of 47uF - 25 V on the WDFBU-PCB on position 2342 (PCB is prepared to this intervention).

Low-output tapes can generate white "fishes" in the picture.

To enter service mode on this machine simply press and hold the stop key on the remote then press and hold the play key on the front of the machine for at least 5 seconds. The remote stop key can be released once the play key has been pressed.

The option bytes are entered at step 40 so you need to press "select 40 select". Enter the correct three digits for each of the five groups A-E, pressing OK after each group entered. Move on to the next group by pressing P+. Exit service mode by pressing standby.

Procedure to erase the codeword:

- disconnect the set from the mains supply

- press simultanuously memory and record

- connect the mains power

- release both buttons

- press then record to erase the codeword

When recording or playing back using the long play mode it is possible that the above models may prematurely eject the tape. The reason for this eject taking place is associated with the amplitude of the tacho signals WTAR and WTAL. The problem can be ove Eject during recording/playback, LP mode

No problem when pressing "PAUZE" during "PLAY":

Pin 7 of IC7356 (TDA8136), voltage = 11,8 V during PLAY

Replace IC7356.

Sometimes no colour in PLAY mode

Tape will not load, Mechanism cycling, and erratic Display.

Check supply voltage + 5,2 Volt; this can be easily measured on the PCB-fuse 1001 on the CHROMA PROCESSING PCB. If this voltage is far below 5,2 Volt, check then this voltage also on the supply-unit. Clean carefully the connection points of connector SM1

This fault was caused by regulator 7356 on the family P.C.B.

The 12 volts line was low and unable to supply enough current.

Totally dead. No output voltage of supply (KSM-800), or far too low

If the voltages are too low, replace the capacitor C2112 (100 uF - 385 V codenumber,

4822 124 41556). If the supply is not oscillating at all, check capacitor C2114, and replace it if necessary by a new one (22 uF - 35 V codenumber, 5322 124 41431).

After a long time, display flickers

AUDIO level too low

Audio not recorded; previous audio not erased

If display flickers at dimmer position 5 (maximum brightness), than replace PTC's 3103 and 3109 on the supply module by another type with codenumber 4822 116 40261.

Ensure that the PTC's do not touch each other after mounting.

Adjust R3390 (PBL) again on 40 mVolt +/- 0.5 DB. by means of HIFI testcassette. See

Service Manual of VR632, 732, 733 and 833 page 3-3 chapter 2.6.2.

Remove connector from cable of erase-head and solder the wires directly on the erasehead. Check also whether metal-flakes are present in the flatcable connection of the audio-sync head.Note: touching the wires can already hide the complaint!

Resolder 2012, replace switching transistor.

REMARKS: Bad soldering of 2012, therefore frequency too high and 7040 and resistor burned.

REMARKS : There can be defective jog/shuttles where in case the shuttle ring is moved to the right and a pressure is put on the jog, there is a short circuit between +5V and ground.

Remove glue under 2623. Glue under 2623 is conductive.

Remove glue under 2350 and 2348 Level of pin 19, 7340 is varying because of conductive glue under 2350 and 2348.

Frequently asked questions

Check for a loose pin in the brake/clutch assembly. If that doesn't solve it, there may be other issues. Refer to the manual for your specific model.

First, disable the child lock using the remote. Then press and hold the "Ch-" and "7" buttons simultaneously.

Check the solutions listed in the manual for your model. This often involve component level checks or replacements.

This manual suggests checking for issues relating to the wow and sound quality near the end of the tape as this could indicate a problem with the tape itself.
