Why would tweeking the pots help. In all my experiance with CD and DVD's I have generally found this to be a BAD Idea, and it's almost impossible (without a service manual and some special test gear) to get them aligned again once tweeked. Once they have been factory set, they shouldn't need any more adjustment. If it stopped after a power surge, then something has gone Faulty.... not out of adjustment.
As far as economics is concerned, I have also found that (unless the machine was an expensive one to start with) if a Laser cleaning, Spindle motor lubrication, and sled assy clean and lube dont fix the problem, then it's just not worth it.

But if you want to try a few things just for curiousity's sake, then adjust the pots to your hearts content.... just don't expect any results, and do it with the power OFF as mentioned before.

 

Do you mean the LASER Diode found inside a PS & Xbox is same w/ the DVD-Rom?
...Anyways, I don't have an old PS/ Xbox & even the New one..LOL



...but in another FORUM said buying a LASER diode is much expensive than buying a new DVD-Rom.

It's the same situation with car parts, a used car is worth less than it's parts in many cases.

 

just had a similar problem my emprex. would burn cds but refused to burn dvds.
i did a firmware upgrade no joy,
as a smoker i guessed what was wrong, took the lid off the drive,gave the laser lens a gentle rub with a damp cotton bud, now works fine -6 minutes start to finish.

> Ok.. thanks Gadget for your precaution.
That will be my Plan B. (Adjusting the Pots.)
...but I was wondering how can I test IT when the power was turned OFF?

I'll remove of the DVD-Rom then adjust the Pots. then put IT back,
...when the adjustment wasn't right I'll just remove IT over & over again?

 

It's the same situation with car parts, a used car is worth less than it's parts in many cases.

I agree w/ you Bill ...
But I have no other option than to make use of this 'OLD Car'.

 

Hi JDC?


Yup... There are ESD sensitive devices inside the drive.. But the PCB is mounted so that the primary side or component side is secured, usually below the disk tray and near the laser and the dynamo, and enclosed with other plastic tray below it.....

KABAYAN!!! ...Tga san u?

Have you ever tried to fix a DVD-Rom?

Your problem is, your DVD-ROM won't be able to read ordinary CD... only DVD's... and it happens after a power interruption....

Exactly right..

My idea here is that, power interruption is not really the cause of the problem.... it just only happen that when the problem occur, there was a power interruption before the event... What I mean here, is that current surge didn't not destroy your optical drive... Because, if you did not use an AVR or UPS, current surge only destroys the power supply, or up to the Mainboard only... The Power Supply of the PC is designed not only for supplying the necessary voltages and currents of the entire system, but also, it is designed as to protect your system, especially the MB, from current surges and spikes... If happened that a current surge is really strange, then the MB might be destroyed but not upto the optical drive...

Yeah, that's why IT can still recognize DVDs.

Also, If you're trying to open the drive just to align something, I think its better not to do it yet... Why?

That will be my Plan B.

First, If there is/are misaligned parts inside the drive, then the entire drive wil not function...You've said that it can still read DVDs,? That only mplies that your DVD-ROM is still functioning, only that it is limited....

I think their was a problem w/ the driver or in the registry or something
(know-how w/ the PC stuff is limited)

I'd try to Uninstall the driver & Install it again but nothing happens.


.

Second, most DVD-ROM failures such yours are not related to mechanical problems...

Software related..

What is the brand/model of your DVD-ROM? Is it IDE or SATA?

LITE-ON DVDRW SHW-16355
...I think IDE . I saw it in the box cover & its System requirements that state this:

> CPU: Pentium 4 1.3GHz or higher
> OS: Windows 98SE/2000/ME/XP
> Memory: 128MB RAM or higher (256MB RAM is recommended)


> Hard Drive: 650MB available capacity; 9GB free
HDD space or higher for creating a DVD image file
(My Hardrive Free Capacity = 6.84 GB only)

What is the brand/model of your Motherboard?

I don't know..I'll check it out after I replied..

What player did you usually use to play DVDs and CDs? Have you tried using alternative players rather than you usually used?

Windows Media Player/ Winamp

NOTE:
The DVD-ROM was burning a slideshow in a ordinary CD-RW
when power interruption occur.
Since then, IT can only recognize a DVDs.

 

PLAN A (Editing the Registry)

I'd search in google & came out w/ this solution.
But the author said in the website, Editing a registry can be dangerous so before to edit the registry it is essential to have a backup copy of the registry & save it the safe place (system restore point)

But as I have mention, my know-how is really limited.

Could anyone assist me to perform this stuff

Any help would be appreciated.

Thanks.

 

hello kabayan,

if you dont have the budget for a new one, try contacting a computer technician who knows somebody selling their unit. there are so many who upgrades their system and they usually sell the old one for as low as P500.00. i guess for P500 or P700 you now have something to spare or maybe ask you itay. brand news now sells at P1,700 to P2,200 depending on the brand.

Hi mozikluv... " kabayan... tga san u po? "

Thanks for the info. I'll try it out.

i guess for P500 or P700 you now have something to spare or maybe ask you itay. brand news now sells at P1,700 to P2,200 depending on the brand.

P1,700 to P2,200 ... 'Pautang naman' ...

 

From the Queen City of the South, Cebu!!!

Kba2yn u pla ITAY qo eh... He's from BANTAYAN ISLAND, CEBU.
But now we're living here in the LAGUNA.

I Haven't tried fixing a DVD-ROM.... But I have an idea what's inside on it.
Try installing the driver using a different source... Just to make sure that u are not using a corrupted installer... You can download some support files (firmware, utilities, etc. from liteon website.... click the link below...

http://us.liteonit.com/us/index.php?option=com_wrapper&Itemid=75


I think it's LITE-ON DVDRW SHW-1635S

Sorry if I'm wrong...

Try using a VLC Media player... just to make sure the players u used has no corrupted codecs.... click the link below....

http://www.videolan.org/vlc/download-windows.html


Then, it's quite clear that, the firmware of the DVD-ROM gets corrupted... Not using a UPS when you are working such stuff will really gets your DVD-ROM in trouble.... I Think its better for you to buy a new or even second hand one, coz' such problem is really quite hard to fix... My suggestions above doesn't guarantee that it will really fix the problem... But just try it...

Yeah, I think your right.

'Salamat Kabayan'

 

as what "broadband" said, your model is shw1635s and is now selling at P1700. try checking with compu shops in your area and am sure you'll find a secondhand.

broadband and i are just neighbors, he's from cebu and am from negros.

P.S. (For Filipino's only)

' Mrn pb u alm n Filipino n nd2 s forum aside from U & broadband???

...just curious.

 

it's better to buy a new one...a brand new DVD-ROM is just as cheap here as with the prices abroad... only that the money is DOLLAR!!

Php 1,700.00 is approx. US$ 40.00

> Either the price of a New DVD-Rom is in Dollar or/ any other currency still it defends upon the buyer's decision/ status.

...when you're rich just like MR. BROADBAND AC [ He said Php 1,700 (U$ 40) is CHEAP] just buy the new one.

> As far as this long thread is concern,

Indeed,
Troubleshooting a CD/ DVD-Rom is really impractical, just purchase a NEW one
or/ if your budget isn't fit ( just like mine )
purchasing a 'second hand' is PRACTICAL.
