I saw this 32" TV sitting by the garbage cans so I went to the door and asked permission to take it. The gentleman said, "lost receipt, son plays games on it day and night, only had it about 6 months, has sound but no video, take it. First thing I did was rebuild the power supply. After replacing 14 Capxcon capacitors with Jackcon's I still got sound but no picture. So while waiting for the gobbler to quit pretending to be lamb, I tore the TV down further and found a blown LED. There are three strips, each having 10 LED's. I am having a terrible time finding a replacement part. MBL-32035D310TF0 V1 56.8mm & 67.8mm

Re: Seiki SE322FS w/sound/no video
Theres only 1 board in this set. I can promise its not a board issue at this point but I'm sure the cheap construction caused the leds to failComment

Re: Seiki SE322FS w/sound/no video
I had the same problem, and am still looking for a replacement LED strip. For now I have "fixed" the problem as best as I can. Since two LED strips were still operational, I put one on the top and one on the bottom. Then I used a small piece of metal (short piece of a bread tie stripped down) to complete the circuit. I stuck one end into one side of the empty plug for the LED strip and stuck the other end into the other side of the plug completing the circuit. The television is working fine now, but I would still like to replace the center LED strip. If anyone has luck finding replacement parts, let me know. ThanksComment

Re: Seiki SE322FS w/sound/no video
I had the same problem too , by shorted (bridged) the bad LED. The TV works good, hard to notice one LED is not light up..Comment

Re: Seiki SE322FS w/sound/no video
Why not try some of those SMT 1W LED's from fleagay? Not had any bad LED sets--except broken screens--to try 'em out on, but better than nothing....
If you pop off the lens, there's a SMT LED underneath....TELEFIX

Re: Seiki SE322FS w/sound/no video
I just took this set apart again for lack of something to do.
I am going to rebuild my strips with the 1-w smt as Alastair E suggested.
I will repost after I have the strips done and back in the set.
It should work. Thanks Everyone.Comment

I am facing a strange issue, I don't have any sound over my internal MacBook speakers and also the video won't start. If I change to my head speaker or via HDMI (speaker on my external Display) the sound works over the head speaker or Display and also the video starts (ex. youtube).
All happened after the battery ran out of power overall several days when I was on vacation.
I tried to remove the battery and then reconnected the battery, and then the MacBook Pro 14 2021 won't accept any power from my power socket. Then I removed one speaker, connected again the battery... -
Good morning everyone,
I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.
The firmware reported is the following:
M:1.00/11107BLP
D:?.??/????????
O:1.00/11107AL
The DSP firmware given the question marks seems corrupt.

Hi all,
Ok so I have this beautiful un55h8000 samsung tv with sound but no video nor backlight. When turning the set on the red light blinks 5 times.
The screen shows no damage and backlight turns on when I disconnect the power supply from the main board. The tcon board only has 2 out of 3 leds on.
I came across this page and followed the different steps: https://techhometravel.com/samsung-u...ight-no-video/
- Unplugging the main board cable at the power supply >>> backlights came on.
- BLU_ON signal from the

Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but...
