Audio Distortion after warm up
Cause:
- Failure in A/V Decoder IC401; or
- Failure in Audio DSP IC501
- Often the audio distortion occurs after the unit gets warm, appearing in both front L & R channels but less in both rear AC-3 channels.
- To determine which IC is defective, freeze the heat sink above IC401 on the MB board when the problem appears. If the problem does not go away, IC501 on the bottom of the board is defective.
The spindle motor rotates immediately at power ON instead of 5 seconds later.
The tray may not come out (displays “EJECT”).
There also may be a dark screen (no video output, no initial DVD logo).
Cause:
Spindle / tray / sled driver IC802 is defective. Video was muted because communications were locked up by IC401.
Repair Procedure
IC802 will feel cooler than the similar IC801 next to it. IC802 may also short the +12V line, producing symptom 1.
Remove the MB board, turn it over and replace IC802 (P/N = 8-759-567-26).
Unit goes back to standby mode during playback or after being left ON in the stop mode. Pressing the MB board makes the unit remain on longer.
Cause:
Broken solder connection at a major IC stops the communications chain and the unit goes into protection by powering OFF (standby).
Repair Procedure
Remove the capacitors around IC401 for clearance and resolder all the pins. If you created solder bridges, you have not applied liquid flux (Kester flux pen) at the foot of the IC legs or you touched the legs close to the IC body with the iron. Remove the bridges with thin brad solder wick. Inspect each pin carefully, then remount the electrolytic capacitors. While you have the MB board out, resolder the pins on IC206; and
Resolder the pins on IC202.
Picture freezes or shuts down when trying to play dual layer (gold) DVD movies.
Causes:
- User may have changed disc DVD PB settings
- ROM IC205 needs to be upgraded or the A/V decoder is defective.
- Enter the Test Mode and reset the user and service EEProm data.
- Enter the Test Mode by pressing Title, Clear, Power.
- In the Test mode, select 2. Drive Manual Operation
- From this menu, select 6. Memory Check
- When the EEProm Data menu appears, follow the bottom directions to return to default values by pressing the Clear button. After you return the data to default levels you need to perform the automatic adjustments with test discs.
- If the new IC206 ROM is already on the board according to service bulletin 58R1 (MR27v1602d-xx, 2XX-1.95version or greater), a defective A/V Decoder IC401 must be causing the picture problem. Replace IC401.
- To avoid cold solder connections when installing the new IC, clean the unused foil pads with an eraser and apply flux before soldering the new IC206 on the board. Afterwards perform the automatic adjustments with all discs (CD, DVD - SL single and DVD – DL dual layer).
After replacing the Laser assembly, EEProm IC201 or Flash ROM IC205/IC206, enter the test mode using the remote control and perform the “Drive Auto Adjustment”. This alignment method uses three standard test discs one at a time to adjust the following:
- DVD laser tilt angle for maximum RF level
- Focus gain and offset voltages to insure reliable RF data
- Tracking gain and offset voltages to locate data quickly.
Cause:
Ripped flex cable, reference # 180.
Repair Procedure
Replace the flex cable (P/N 1-791-200-11) and secure the new flex cable so the rotating tray table does not shear it.
Tray does not rotate.
Cause:
Tray Driver IC652 defective.
Repair Procedure
Replace IC652 (P/N = 8-759-522-08) { This only applies only to multi DVD changer model DVP-C650 – }
Tray does not Eject. Displays :”LOCKED”.
Cause:
Nothing wrong with the unit. Tray is locked out in the display unit.
Use a SONY DVD remote to lock or unlock the tray
Cause: Nothing wrong with the unit. Tray is locked out in the display unit.
Use a SONY DVD remote to lock or unlock the tray.
Repair Procedure
Lock
- With the unit OFF (red light), press the following buttons on the remote: 1, 4, 1, 1, Power.
- The unit will come ON. Once a disc is detected, the tray will no longer respond to the eject button. The display will show LOCKED each time the eject button is pressed.
- With the unit OFF (red light), press the following buttons on the remote: 1, 4, 1, 0, Power.
- The locked display will no longer appear and the tray open button will work normally.
Cause:
Tracking coil fuse F402 open.
Goes to Standby (red light) after powering ON.
Goes to Standby (red light) while playing a disc.
Cause:
Syscon IC102 failure or there is nothing wrong.
Repair Procedure
- First press the front panel power button.
- The power light should change from red (standby) to green (ON), then back to red. (No light àred light àgreen light à red light).
- While the red light (standby) is ON, press either the PLAY or TRAY OPEN/CLOSE button. If the unit powers ON again there is nothing wrong with the unit. This is normal. The unit entered the standby state after pressing the latching front panel power switch. Think of the front panel ON switch as a master power switch. The DVD player will not respond to the remote unless this master switch is ON (depressed).
- If pressing the PLAY or TRAY button does not power the unit back up, check for B+ by looking for Xtal activity (X101 = 2.4Vp-p, 1.6Vdc) at IC102. Xtal activity means there is B+ but does not mean the entire IC102 is OK. Replace IC102.
Cause:
Syscon IC102 failure.
Repair Procedure
- If the display showed “STANDBY” after pressing the front panel power button, the power supply was not loaded down by a short circuit and it is OK.
- Tray driver IC402, its controller, IC404 or SYSCON IC102 must be causing no tray movement. Replace IC102 first.
No chroma from the S video output jack; or
No component video (Y, B-Y, R-Y) output. The composite video output is OK in both cases.
Cause:
Output Video Buffer IC101 failure
Repair Procedure
In the following steps you will remove the MB board from under the mechanism deck and use the jig to operate the board and the mechanism outside the unit. This way you can check the video signal entering the video buffer and verify IC101’s defect.
You can damage the laser when unplugging the laser assembly. To prevent this, either short out the laser diode with a solder blob on the ribbon cable or use an anti static mat with a wrist strap.
- Set up the jig (P/N J-6090-100A) to operate the MB board outside the unit (you have to take out the MB board anyway to replace IC101 so it will take an extra two seconds to check the signal and prove IC101 is the cause of this symptom).
- Press power ON, insert a disc and press the play button to keep the unit powered ON.
If these input signals are present at the test points of the extender board but not at the rear panel jacks, replace buffer IC101 on the bottom of the AI board.
Alternate Test Procedure
You can also check for chroma leaving the MB board at IC502/pin 77 without disassembly. IC502 is located to the right of the tray/laser assembly and accessible while the player is fully assembled.
Picture is distorted or there are Digital blocks that appear during the movie.
Cause:
A/V Decoder IC502
Repair procedure
In older DVD players this symptom is characteristic of a weak laser. In this newer DVD player model, this picture-related symptom is caused by the A/V Decoder defect. Much MPEG unscrambling now takes place in one very complex A/V decoder instead of discrete parts, making it easier to relate a picture problem to one part. Replace IC502.
Tray does not Eject. Displays :”LOCKED” [DVP-S350, DVPS560, DVP-S560, DVP-S570.]
Cause:
Nothing wrong with the unit. Tray is locked out in the display unit.
Use a SONY DVD remote to lock or unlock the tray.
Repair Procedure
Lock and unlock are the same procedures. Each time the code is entered, the unit alternates between lock and unlock.
Lock
Press the front panel power switch and wait two seconds for the unit to enter standby (red light). With the unit in standby (red light), press the following five buttons on the remote in this order:
1,
Angle Change,
Sub-Title Change,
9,
Power.
- The unit will come on. The tray will respond to the eject button. However, once a disc is detected, the tray will no longer respond to the eject button. The display will show LOCKED each time the eject button is pressed.
With the unit in standby (red light), press the following five buttons on the remote in this order:
1,
Angle Change,
Sub-Title Change,
9,
Power.
- The locked display will no longer appear and the tray open button will work normally.
