    Magnavox 19MF338B voltage from PS but no pic or sound? :{

    Hey All,
    I am working on Magnavox 19MF338B this week. I plugged it in, press the power button it gets the green light on the power button, but I dont hear any relay, i have no picture, no backlight and no sound. I tried to hook up a source and click through inputs with the volume up, but nothing. I opened it up and check voltage from the power supply, seems my 5v and 12v voltages are good so I dont know what is up here. Also another note. when you hit the power button and green light comes on for the set, no matter what you do on the power button or the remote, you cannot get it to go off, the light wont turn off at all unless you unplug. Any help would be great, thanks!

              Trip light 2400 watt line conditioner bought used issue with low voltage oscillation going on between relays
              by sam_sam_sam
              I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them

              The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly

              Now...

              Monitor Audio RSW12 - Green light, but no sound
              by MOSSEP
              Hi

              Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

              Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

              The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

              I have already tried replacing all of the...

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              what i went through dealing with my mobo with dead onboard sound!
              by ChaosLegionnaire
              so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

              i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
