The dvd player in my unit has hasn't worked for about 2 1/2 years now. Before I get a new system, is there anything I can do to resurrect the dvd player. When you put in a dvd, it spins up for about 3-4 seconds, then the unit ejects the dvd. The unit says "Loading" while spinning up. That's all. Any help would be greatly appreciated.

Re: DVD is dead
Wow , with the unit sitting for two years, you could have all sorts of problems now. Most likely back when the unit stopped working, the spindle motor was bad, as that was the problem on almost all of these types of CD players. Now though, if the power supply capacitors are not shot, the laser assembly could also be bad. My best advice on this unit? Can it and start out with new equipment. Good Luck

Tries to play more than one DVD disc.Tries to play many DVD disc should be original DVD disc ok no DVD+R copying disc ok.If ur are still getting signal just saying loading signal awhile than say no disc show up, and u did playing it with many dvd original disc.Than the DVD player laser eye reader could be ditry.Tries websites like Amazon.com,Ebay.com to buy a DVD disc set that said like DVD players lasers eyes cleaners.Used it as directions said,if u still getting the same result mean ur DVD player laser eye reader it is dead,not worth repairing the DVD player if the DVD player laser eye reader it it dead,because the laser eye reader it is 90% important to the DVD player unit and the cost of it by replacing it will cost the same as a new DVD player unit.
Litium battery in this portable DVD player already in the unit like the last 2 years?Yes.The litium battery require replacement.Tries websites like Partstore.com,Ebay.com,Amazon.com to buy a new litium battery for the replacement.
This problems could be anythings wrong in it unit circuitries.Tries the unit unplug,replug it back like about an hour later.For the unit to do a resetting back to the factory setting.The unit should be working again.If still have the same result,the unit have dead circuitries board problems.This unit just a basic DVD player only wright?Yes,unit not worth the price to repair it.The basic DVD player only cost like about $40 only brand new.
any flashing red powerlight ?? (assuming theres any charge left)
if the powerlight flashes quickly then the units kaput ( bin it)
slow flashing means the microswitch may be stuck (the one that turns off the screen when you close the lid.
you may have to be sneaky at a dealer and ask to plug in to a new mains unit ( most new panasonics still use the same power supply voltage and ampage. if it works then run away quickly and go buy a universal power supply, if it doesnt , well your in the right place tobuy a new one ??
Local repair shop said it's un-econimical to repair.
Admitted they had no service manual.
Said they could 'have a look' but likely repair cost would be over $300. Charged me $50 for quote. Useless Gits.
My opinion & findings.
Power supply sensative to spikes.
I Suggest a power filter in-line with unit.
Disconnected all sub-boards from main.
Hiccuping PSU (5v wobbles between 2&3V).
Replace switchmode IC & feedback IC. No change.
Eventualy identified short-cct diode as listed below.
0402-001194 Diode is a Gen-purpose 200V 2A diode. I used a 1n4007 (1A), so I expect to have to replace it in future. It's "D1S35" located very close to right rear corner of main board, part of 15V and 12V rails. Next time I'll use a 'faster', higher rated diode.
I also had no clock progression. Time could be set but would not advance. Been like that for ages - I thought it was a user clock-setting error. Identified Dead 32.768 khz crystal (XT601).
If your alternate DVD player has digital audio out you can make this connection via the 'optical digital in' port on the rear of the unit which corresponds to the Video 2 function. I have done this myself because the inbuilt DVD function in the Sony unit is dead (fixed once under warranty, problem recurred about a year later, same issue as other unsolved posts on this board, DVD function hangs, system won't switch off, etc. common problem with this unit, crap product).
This is my opinion only, but I have worked on many many DVD players, and if you don't need anything fancy, then go for the $30.00 unit. Actually, I would look for something in the $50.00 range, as the $30.00 units are very cheaply made. I have often worked on a $100.00 unit, followed by a $50.00 unit, which had the exact same laser and mechanism inside, the only difference being the brand name stamped on the front.
But.... You could purchase three $30.00 units, for $100.00 and if you used them one at a time until the last one died, I dare say they would very likely outlast the $100.00 unit by far.
I've probably just confused you now, so I'll just end by saying that on a regular t.v., the picture will look just as good using either option, and you can have good luck or bad luck with any piece of electronics expensive or not.
