Mine is probably dead.

Stopped playing HDDVD... then DVD... then recently CD.




Found in:

• Toshiba HD-A2
• Toshiba HD-A20
• Toshiba HD-XA2
• Toshiba HD-XF2
• Toshiba HD-XE1
• Onkyo DV-HD805
• Integra DHS-8.8

If you have a sleeping unit that could be recycled!

Since I was doing to research on drive vs. model, here are more data points:

The Microsoft XBox 360 Add-Onis using a different connectivity for the drive ref. SD-S802A.



3rd generation players are using a different drive ref. DAV-RB722:

• Toshiba HD-A3
• Toshiba HD-A30
• Toshiba HD-A35
• Toshiba HD-D3
• Toshiba HD-EP30
• Toshiba HD-EP35

Looks like there might be some potentiometers near the laser, have you tried adjusting them or anything?

I couldn't see anything looking obviously like a potentiometer but I'll give it another look, thanks!

Right, the ones marked VR1 and VR2. Not sure if there's detailed guides out there for adjusting HD DVD lasers, but they shouldn't be too different from DVD lasers.

So...

The belt is fine.



This is the exact optical bloc from https://www.repairfaq.org/sam/cdfaq.htm:



I have the readings as follows:

• VR1 = 25.57 kΩ
• VR2 = 28.24 kΩ

Should I increase (less current) or decrease (more current) these values?

Julien

Lowering the resistance generally increases the laser power, so I'd make a small adjustment, measure the resistance, see if a disc will read, and repeat.
