Loading fault the unit just comes up with the words loading and will not respond to any functions or buttons.I have changed 4 caps on the power board which had blown tops can some one tell me if any othe caps require changing and what numbers are they I do have a schimatic drawing of the PCB's.Or is this not the fault Please help.

Re: loading fault

Check power cables to dvd and hd. voltages should be 12v,gnd,gnd,5V with and without load. if voltages drops with load then fault is probably with caps. I changed one cap when voltage dropped in dvd powercable(5V). cost only 0,50€ to fix powerboard. there is a high risk for electrical shock so if youre not familiar with electrical devices and dont know how to perform these checking operations and so on... then PLEASE take your unit for professional

The disc tray of my philips cdc wont change when i press the load button

Either the loadimg belt, or the gear wheels might have the fault. Replace the loading belt first, if your are handy.

The DVR would not power up. I replaced c17,c19 and c23 as detailed on other posts. Unit now comes on in standby mode. But when pressing the power switch, the power comes on for about 5 seconds and then...

Usually when replacing capacitors in a switchmode power supply, it is recommended that ALL the caps be changed in one go, rather than just replacing a couple (it is possible that the PSU is not fully functional since you only changed a couple of caps, therefore putting stress on other components such as diodes etc. hence why it won't stay on for longer than 5 seconds).

I suggest that you go with the easiest (and cheapest) option first - replace ALL the electrolytic capacitors in the PSU, this may totally solve your power standby problem - and the unit should remain on and function properly.

I also suggest replacing the 3 caps you already changed (C17 C19 C23) with fresh ones along with every electrolytic in the PSU - see if the unit remains on after that. If the unit still goes back to standby or shuts off, then check all of the other components (including any IC regulators and diodes). in the same circuit.

Where some electrolytics have strange values, replace with increased capacitance value and/or working voltage of each as required (note the value/voltage etc., of each of the original caps before you change them).

The good news here is if you do the above suggestion, and it works out well, all it will cost you is a bunch of capacitors and/or other parts as needed. No workshop charges if you do the repair yourself.

Fingers crossed that all you need is the abovementioned caps; but you need more than 3 to complete the job.

Unable to either use the remote or the buttons on the player to operate the player. The light is red, replaced battery, and still will not function. Isn't the light supposed to change to green?

The power board inside the DVD is burned/ damaged.You need to take it to the service center to replace the power unit.

If you know what to do, you can open the DVD case, then replace the power board.To locate it, simply follow the power cord, power cord attached to the power board.
Replace with same type of boards.

Yellow light - no response

I solved same problem by replacing capacitors on the power supply board.
It is very easy to get his board out -- make sure the unit is unplugged first and sits for about an hour to drain any caps that do have a charge!!
The cost of all the caps on this board is about $3 from Allied Electronics, plus shipping, which would likely be more than $3. Radio Shack might have them.
The obvious offender in my case was the 2200uF 10V cap which was bulging at the top, a sure sign of a failed cap.
If you don't have experience or ability with a soldering iron or have a friend who does, you could try a repair shop, but they would charge $$$ to fix something worth only$ in the first place.
But when this thing works, it's a good unit.
Good luck.

Unit unresponsive - see detail below

Thanks to the help on this forum, I was able to fix my DRC8335 power supply. C226 was the problem, went to Radio Shack and found the 470uf 35V replacement. It came up and worked like a charm after soldering it in. (See the picture of the cap on the board). It was just slightly swollen when viewed from the top but when i removed it, the bottom was really distorted. Thanks to micro065 and Mike Powellebbca66.jpg

A disk is stuck in the tray of my sony DVP-NS305 player. The disk tray will not respond to either the hand piece or the button on the player itself. The word "Locked" comes up on the display. How...

Unplug power cord, and whenb you plug power back and restart the DVD, keep pressing repeatedly the eject button on the unit.

Do this a couple of times.

If it does not work you will need to take apart the unit to take out the disk. In this case consider calling a qualified technician if you are not sure about how to do it.

Pioneer Dvr-633h-s

This idea may work when a multitude of devices become erratic in function, display info on the screen that is incorrect or just won't work at all.

Lightning strikes near by (even with the device connected to an isolation strip) power interruptions and excessive heat can cause electronic equipment to mal function.

Do the following:

Make certain that the device has ADEQUATE VENTILATION!

Remove all dust from the grill in the back of the unit in the fan location.

Un plug the device for at least 24 hours and permit any stored current to drain from the unit.

Then restore current to the device.

If the problem persists, plug and unplug the unit several times, observing the change in the screen, until the info there changes to the proper display.

If this does not work, you need a tech assist.

Unit want come on

I ordered new Capacitors for my DVD Player 2 Panisonic 1500uf 10v 105° caps and 1 Panisonic 1000uf 10v 105° cap and soldered them into the powersupply where the oviously swolen / leaking capasitors were and walla it powers up and no more high pitch noise but I can't get it to eject the cd or anything. It shows on the screen but it just says loading. My guess is it did some dammage to other components inside the machine. I suppose it was worth a shot but now I am going to toss it and get a name brand. ILO isn't in business anymore... Oh and yes I did try the reset button abov the DVI connector...

Unit in constant Loading state

Same problem on my JVC DR-DX5SU. Says "loading..." and will not respond. Factory solution is to quickly unplug and plug / or unplug for several hours and plug-in. I suspect that is to cold start and clear error flags. Did not work for me. I looked at the power supply board (immediately behind the DVD drive, on top of the hard disk). I noticed one capacitor was "bulging" on the top. See photo. Electrolytic caps should never be bulging - if anything, the top should be slightly concave.Cap was SAMXON 1500uF,10V,1400mA ripple - I suspect either voltage or current ripple spikes were exceeding its capability. Replaced it with a Panasonic EEUFR1C182 (, 1800uF, 16v, 2470 ripple current, to give it extra margin. Runs correctly now.1_30_2013_1_21_49_pm.jpg
