Loading Problem JVC DVD Player Repair
My friend and old colleague from a previous temporary job brought me his DVD player that failed ejecting a disc that was still inside. And neither did it play the DVD movie because the display kept showing LOADING without doing anything else. And also the Power button didn’t switch off anymore while only showing LOADING. And a blue light was constantly visible in front of the DVD player.
It was time to open up the device by removing 4 screws on the sides. And another 5 screws on the back of the case.
After the screws were removed the metal top cover was easily taken off and the Power board with 3 bulged e-caps on it was unmistakenly causing problems. Below the labels of this JVC player.
And next photo shows the three 2200uF 10V e-caps on the Power board that no doubt needed new replacement capacitors before they were removed. Again problems caused by those always deteriorating e-caps. The bad caps are marked by red pointing down arrows.
Followed also by a photo of the inside view looking in from above, and a photo of the power board’s solder side.
Above the solder side Power board. Below the connectors on the back of this JVC.
Following photo shows the DVD writer that is used in this JVC player/recorder.
I also tested this DVD drive on an external Power supply to see if it would eject its disc. So making sure that this player still worked which it did. It is attached by a nicely constructed decent special flat cable to 40 pins IDE adapter cable that connects the DVD Player to the decoder board on the right. And I measured the 5V and 12V DC signals on the Molex DVD power connector. After the new e-caps were soldered in place and after placing everything back the JVC player worked splendidly again! As last photo shows.
The TV shows DOKTER TINUS, a Dutch series that is available on DVD. And is the DVD that was left inside the DVD player as it was brought to me. The TV is the Medion DVB-T receiver that was also repaired and written about in a previous article. It has 3 HDMi inputs, 2 scart inputs (one for a decoder), S-video, PC input, Composite, a DVB-T tuner with in and output. Which makes it an ideal universal TV or monitor for testing purposes. And on top on the JVC player my superb SUPERIOR 4in1 programmable IR remote control is visible. Which I need to control my Medion with because none of my other 7 or 8 programmable IR Remotes were able to control this Medion TV.
And the Superior 4 in 1 shown here is the USB programmable Remote. (look at the small micro USB port on its right side).
I also have another almost identical second 4 in 1 Superior Remote that doesn’t have the USB input port but it can also be programmed with an USB IR programmer from Superior that is also available on eBay. I mention these IR Remotes especially because it knows about 260.000 unique device codes (all downloadable for free!). And when you need one for a device that is not yet supported you can ask the guys from Superior to make it available which they then make downloadable as free update before the next day if they can. Which makes it a universal remote unlike any other IR remote that is also capable in controlling 4 different devices in one remote at the same time too!
After this repair it is again time for me to order a couple of new 2200uF 16V capacitors because they were the only ones I still had left.
