Very helpfull information and I highly recommend this source for needed information about your products.
 ;
More than pleased with my prurchase, very good product for the price.
;
This is a good quality scan of the service manual which includes an assembly diagram, block diagram, schematic, and parts list. Exactly what is needed to repair my KR-V55R receiver.
;
Excellent concise manual. All needed information was included. Typeface and diagrams were clear. Very fair price considering what others are charging. Many thanks

Response is a little slow- I had to wait 12 hours to receive download link but it says that it may take up to 24hrs.
Manual is old and was not produced in PDF- scanned copy is exellent.
Overall- value for money- I recommend
(5) Lighting in green, and then in red (Alarm of power voltage error)
Unlike [lighting in red] in the STANDBY mode, [lighting in green] continues for about 30 seconds without any output of images and audio signals. Since then, the mode turns into [lighting in red]. Lighting in red (Caution) How to reset the alarming condition The alarming condition can be reset when an OFF� ON setting is repeated twice for the main power supply in the state that the LED is lit in red. The interval between the first and second settings is not particularly specified.
Make an OFF � ON setting twice for the main power supply in order to reset the alarming condition. Is the LED lit in red after it has been lit in green for about 30 seconds?
NO
Normal
Refer to P7-1 "HOW TO DIAGNOSE THE PDP MODULE".
YES
When the main power supply is turned on in the state that the AD, PD, and PH connectors are disconnected, are there the Vs (170Vdc) and Vd (60Vdc) outputs at Pins �-� to Pins �-� of the PD connector and a 5Vdc output at Pins �-� of the PH connector? In this case, is the LED not turned in red after it has been lit in green for about 30 seconds? At that time, however, no images are generated.
YES
The PDP is fault. (Caution) The voltage values of Vd and Vs can differ according to the PDP. The method of checking these voltage values is obtainable from [2. Adjustment of the power unit] in the method of adjustment.
NO
When the main power supply is turned on in the state that the PA and PV connectors are disconnected from one after another, is there a 12Vdc output at Pins �-� of the PA connector or the 12Vdc and 6Vdc outputs at Pins � and �-� of the PV connector? In this case, is the LED not turned in red after it has been lit in green for about 30 seconds?
YES
The MAIN PWB or the AUDIO PWB is fault.
NO
Is there an output of 3.3Vdc available at Pins � ~ � and 2.5Vdc at Pins � ~ � in the state that the PA and PV connectors are returned to the former state, the main power is turned ON, and the PN connector is disconnected? In this case, however, this check must be finished in 30 seconds. Otherwise, there will be power tripping on account of an alarm.
NO
The Power unit or the PN connector is fault.
YES
The MAIN PWB is fault.
