Can anyone offer me some assistance with a freezing player?

[spankey]

I have a magnavox 751 dvd player. ITs about 2 years old. All and all its a great player. Plays all my SVCDs with NO issues at all..

Heres whats happening..

Out of the blue my player after about 40 minutes of playing from a cold sit, it freezes and becomes unresponsive.... I power it off and power it back on, begin play again, and the video is all blocky looking? Then it freezes again...

Could this be a heat issue? Or is it something else....Bad laser maybee?

Anyone out there repair dvd players that could offer me some diagnostic advice.,, I do not want to chuck it because it really is a great player..

I picked up a Toshiba today at best buy for $79.00. Half the price I paid for the magnavox.

I like this player except it does not play me svcds.... But all and all its a nice player..

Any rate.. This happens, the freezing. On normal dvds and svcds alike. So that rules out its an svcd issue...

It just to me seems like heat. Because I can run it fine for about 40 minutes then it freezes.....

Could it be cheap repair? Again, I really would like to save this player for my bedroom and place the toshiba in the living room....

Anyone any ideas?

Thanks so much for your help and time...

Open it up and have a look at the loader - chances are if it's reasonably dated it'll be a standard DVD-ROM drive, if you're lucky - just perform a swap out Sampo style (see here)

It sounds like an intermittent component to me. Heat related, shouldn't be too hard to isolate with a can of freeze spray. Buy a can of this from a local electronics parts supplier or order from a website such as this one:

When the unit starts having the problem, spray it directly on the chips on the main board being careful not to tilt the can, the liquid may come out. It should spray a cold mist and cool the components back down, and you should be able to isolate it. From there, if you determine what component is bad, and you're able to solder, you can order the part from the mfgr and replace it yourself. It is possible that the laser could be bad, but by using the freeze spray you can determine if the problem is on the main board or not. If freezing all the chips doesn't clear up the problem, then it is more likely to be the laser pickup assembly. The freeze spray is fairly cheap (~ $6.00) and will save you a costly laser replacement if it isn't needed.


One brand of freeze spray, comes in a can like this with a flex nozzle.
