Vcr troubleshotting - Computers & Internet

The first thing to try is to clean the laser lens- you can use a qtip and alcohol, or a qtip. They also see disc cleaners that work well. Aside from that, you might have to adjust the laser head, which requires taking the cover off the unit and tweeking the adjustment screws. Of course, the first thng to check is to see if the unit will read older dvd's that have worked before. If they don't work, the unit will have to be cleaned, troubleshot, and fixed.

Good luck, and hope this helps.

These devices are usually protected at the circuit board and power supply level by fusible links- small resistors, that act like fuses when spikes hit the device from line voltage fluctuations. You could also have a faulty power switch, or bad power supply.
The unit will have to be troubleshot, and tv or computer shop should be able to do it. Get an estimate first, but it will probably be cheaper than buying a new one.
Good luck, and hope this helps.
