In customers Main Menu, under Functions, the settings for "SQPB"-Playback (S-VHS 

Quasi Playback) can be set to "ON" / "OFF" or "AUTO" (Standard ="AUTO"). 

In case of fault "SQPB"-setting will be set to "ON". This will effect higher FM- range (in 

respect to S-VHS range) but at VHS playback some signal noises which are over VHS 

range may create spikes in pic (related to tape material). 

To solve problem Menu setting for "SQPB"-Playback should be set to"AUTO"

Philips VR813 Eject during recording/playback, LP mode 


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 

Philips VR813 Timer. Some Programme listings do not support this method of setting theTimer. 

Philips VR813 If "PAUZE" is pressed during "REC", tape is ejected and set 

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

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

Philips VR813 

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

too low 

Philips VR833 After a long time, display flickers 



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. 

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). 

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.

When the VCR is connected to the EXT-2 SCART of a TV that supports easylink, the 

output of the VCR is automatically switched to Y/C to perform the best picture quality. 

This setting cannot be overruled. Therefore it is necessary to use a FULL SCART
