Power issues with panasonic tc32lx70

The Panasonic CN-MW100D is a portable navigation device. If it's not turning on even though power is coming to the unit, it could be caused by a few different things.

• First, check that the power cord is securely plugged into both the device and the power source.
• Second, check the battery level, if the device has a battery, if the battery is dead, replace the battery or charge it.
• Third, check the fuse, if the fuse is blown, replace the fuse.
• Fourth, try doing a hard reset by holding down the power button for 10 seconds.
• If none of the above steps resolve the issue, then the problem may be with the internal hardware of the device and it may need to be repaired or replaced.

Hi,

Two possibilities:

• the laser eye (lens) is dirty, weak or defective. The unit no longer can sense that a disc is present and therefore will not initiate servo motor engagement. Pls try cleaning;
• the spindle motor is weak or defective. This might be of additional information.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

do you get any error message ?

Yes, this seems to be a powerboard issue due to power fluctuation. I suggest that you take it to a technician.

You may have a dirty coil so unit shuts off on high head pressure.
Turn unit off and clean coil

This is most likely a power supply problem.
F61 for model SAHT75 = Power amplifier output error or power supply circuit error.
Supply voltage for IC501 (Power Amplifier).
Approx. +60.0V dc at pins 3 & 20.
Approx. -60.0V dc at pins 4 & 21.
A qualified engineer may check the above voltages.
------
Another possible solution might be to hold down the power button until the unit restarts itself a few times, and/or before-hand unplugging the unit from the outlet.


Please be careful when working on any electronic device and let me know if you have any further questions.

Hi, I have the same issue ! ... Can you let me know if you fixed it please.

The Panasonic Gaoo sets were top of the line in it's day, the problem you are describing is a vertical deflection issue caused by bad solder joints and a few parts. I recommend a tv technician to fix the set.

I would chack the solder connections at the convergence ICs first. Since the set "recovers" on its own, it suggests a connection issue rather than a defective component. Also, if the ICs were installed without sufficient heat sink compound, this could happen as well. Look at low valued resistors in the area of the ICs for signs of overheating as well.

Keep us posted on your progress.

call panasonic if there are that many posts maybe it is a recall issue and they should know about it.
