- I got this Panasonics DMR-EX769 DVD Recorder at the car boot sale for £4 and was told by the seller that it was all working fine. When I went to test it the Please Wait message stayed on the screen for ages and then when I tried to turn it on it kept going back to Please Wait.
This is how to repair a DMR-EX769 power supply and replaced visually bad capacitors.
The method I used in this one was slightly different as I didn't have the correct capacitors to hand. I had to use 2 capacitors in parallel to make up the capacitance needed, which is a perfectly acceptable way of fixing this and in some ways better as it lowers the ESR of the circuit.

Something therapeutic, watching theses videos
Thank you. I find the the same thing when I watch other similar channels and also when I'm actually fixing these things.
This channel should be far bigger than it is........I love watching your videos sir as they are extremely helpful.... Thank you!
Big thanks, I appreciate that. 👍 I'm glad you enjoy the videos. It would probably get bigger if I uploaded more regularly but not everything I buy is broken.
Thanks Lee for another great video. I find it was a period in early 2000's when the caps were rubbish . Newer ones seem to be ok, a good source of used caps is old computer motherboards.
Thanks for watching and the comment Bill. Yes there definitely seemed to be a problem around this time as many of these machines from that era have the same problem.
Another great job you did on the Panasonic dvd recorder there and a interesting fix too Lee at least the price of capacitors are really cheap when it comes to replacing them for fixing - nice 1 mate 👍
Thanks mate, glad you enjoyed it. It's even nicer when you get get the capacitors free from other junk I have laying around but sometimes you just haven't got the right one. 👍
I use bits box electronics for small component orders. The prices are on a par with the big distributors, without the ridiculous handling charges.
Thanks Ashley I'll take a look at them. 👍
It's not clear in the video, and I could be wrong, but I am guessing your Panasonic unit has a 160 GB IDE HDD. My DMR-EX78 which I originally purchased as a clearance item in 2012 from a now defunct appliance store for $145 AUD (manufacturer date code on the rear panel shows the model year as being December 2008) has a 250 GB IDE HDD and it worked last time I tested it, but the real downside with these models besides the horribly slow IDE drive, is no HD tuner (SD only) - that puts me off using it. However, for £4, you scored a repairable bargain.
I can't remember what size the drive was. It sold very quickly after I repaired it. I do prefer the newer models with the HD tuner/channels but the SD models still sell for some good money in the UK
for 4 pounds , i won't complaint 😆
I don't complain but that's the only reason I buy stuff cheap as I buy it as though it is broken. I just don't understand why people just say "it doesn't work" I would still have paid £4 for it. It was a bargain. 😉
