|
|
The problem with this dvd is that not read the disc. The sequence that happens in this way.
1.- when i select open i put the disc then i close, all normal.
2.- When the disc is located it start to spin for about 30 seg.
3.- Then it stops and no respond to any button except open/close.
4.- I checked the motors and apparently are good, I powered one by one and all works fine.
5.- According to it I believe the problem is the optical lens.
What do you think? please help me.
It is MIray model dva-060

Hi young fella- yes you are probably correct about the laser- they don,t last long!. Sometimes cleaning the lens with a cotton bud will help- there are meters available to measure laser output power- expensive- I don,t have!. Generally, remove magnetic disc cover to expose lens, then open close- stand about 45' away from lens- if good will do an up/dn dance - a visible red beam will shine- the disc will spin- if none of above can be power supply fault, disc motor fault, logic board fault, or even fractured ribbon connector- there are a couple of vr on laser pcb- mark & try vary - usually no good- as I have said before, these laser assemblies & the package are some of the most unreliable electronic thingo,s ever foisted on a gullible public!. B/R, Troo. |
