Hello everyone, I'm repairing a Denon AVR-1509 amplifier, I can't find the specifications of the D534 diode anywhere, I know it's an AX52 diode, but what kind of diode is it, what specification, what specification? Please help
Hi! Good diagnosis! My Denon avr 1603 has a constant buzz noise around 100hz on every channel. If nothing is connected the amp itself also buzzing a bit.... Any tip?
@@kofikwakyeagyekum6487 can you try to test out a different audio source ( input) it could be your input gain is too high . Or possibly the speaker is overloading.
@@sharndhayanithi1856 that is not the case sir, I have tried Tuner,phone,tape1 tape2,cd and different speakers sir but all sounded same,if I play Only the preamp direct , still I don't hear that distortion, distortion is within the power amp
@@kofikwakyeagyekum6487 can you check if you have any defective capacitors in your preamp. Also connect a headphone to the amplifier output ( it's should be in the front ) and test if you have the same problem.
Hi, Thanks for your video. I have a AcBel FSA011-031G also known as IBM 94Y8109. Do you have the pinouts of this one? How to convert this IBM PS? Thanks
Gidday mate! Came across your channel researching my problem Denon3310... Do you know if this voltage regulator issue is a common problem? My unit has an intermittent power supply issue (i guess). But it did power on for an hour when i took it to be repaired. Nothing was done it just randomly worked... I've got a 1513 with a similar issue... the timing is the same... they both just won't click that second relay... if you have an idea please let me know... if not thanks for the vids anyway. i appreciate your effort.
Hello, I have a device like this denon avr-1908 I made a resert and the display stopped working, can you give me an idea because I'm not working, thank you in advance. hug from Portugal.
mine does not seem to play very loud on frequencies above 4khz and the tweeters in my speakers are working fine on a different amp so im confused on why its doing this
Hey bro, do I need to get the board out to solder those transistores? I got the exact same situation but in my case I need to replace the 6 on the top left.
It will be easier if you take the board out but you don't have to . Make sure the solder iron is set to high temperature. It's a bit hard to pull out these SMD transistor.
Had the exact same problem with this TV. One of the MOSFETs was in short circuit, after desoldering it TV started with the other 7 MOSFETs connected. In my case one of the buffer board (SD), was also damaged so I had to replace it. One thing that I think is missing in this video is how you make sure that the problem is in that board (SC board). According to Panasonic service manual, the 7 blinks can be created by the SC, SU and SD board (the three boards at the left side of the TV). When disconnecting the two cables attached to the SC board (as he shows in the video) the 7 blink code should disappear and the light stays green. With this test you confirm that at least one of the three boards is damaged. What you can do next is disconnect the SU and SD board from the SC, and reconnect the two cables, if the 7 blinks appear then it is definitely the SC board that is damaged, if the TV stays on with the green light, then the problem is in the SU or SD. Final test is just connect one of the buffer boards, SU or SD and discover which one is triggering the error. Hope this helps someone!
Hi, Shan. I have a Panasonic Viera TH-R50PV8A model TV. I have the same problem as shown in this video (7 times red light blinking) is it the same board problem in my TV or it could be something else, and many thanks for this video:)
Ohhh man... thaaaaaanks for this video... so hard to find any info about these bad boys... I’ve got 4 here someone dumped a massive Hitachi storage conveniently in front of my house hahaaa
Good work, but sometimes its easier to just test for a faulty capacitor as there known to cause excessive noise. Would be interesting to maybe do follow up soldering video perhaps?
Hi. need your assist. as per below detail please confirm how to switching for 12volt. Power Supply, 650 W Xserve Late 2006 614-0385,6140385,API5FS44 661-4196,6614196, 614-0385,6140385,API5FS44
Hi There Hope you are well. I’m trying to fix my Panasonic TV.( 7 blinks) Could you please let me know how to check the board or capacitor you mentioned on ur video. Thanks
Thanks for the video, got a bunch of PPD5002-2 PSU-s and your instructions worked perfectly to turn them on. The PPD5002-2 was used in in Hitachi AMS500 storage controllers. Additional disk enclosures for the AMS500 used Hitachi PPD7003(PHO840-30) LF power supplies, it has the same output connector but pinout is a bit different: To turn on the PPD7003 using your pinout schematic: connect B4 to A5 and B5, then three 12V output rails and fans get turned on. Connect A8 and B8, then two additional 12V rails and two 5V rails turn on along with green ready LED at the back and fans go to full speed mode. Power usage at 230V: PPD5002-2 no load idle full fan speed ~60 W, idle default fan speed ~42 W, idle fan off ~36 W. PPD7003 no load idle default fan speed - ~30-60 W drifting.
I have Panasonic TH42PD60U 2006 IT IS NOT WORKING SINCE YESTERDAY AND I TRIED TO GET PART TNP3794 AS U ADVISED BUT I AM UNABLE TO OBTAIN PART. I TRIED LOT OF TIMES BUT IT IS NOT AVAILABLE. IT IS BLINKING 7 TIMES.
my partner was going to throw one of these away. its in mint condition with remote and all....I brought it home fired it up and happened to notice 7 flashes. (im an auto mechanic so I am familiar with flash codes) anyways. what are the chances of these tvs having the same fault issues. ( like the one I have having a bad transistor as well) I think Im going to crack it open and give it a go. I am somewhat familiar with your tests ohms checking desoldering ect....I think it would be sweet to fix this for just a cuople bucks.
