Standby light on, but won't power on

When plugged in, the standby light is red. When I press it, the standby light turns off, and doesn't work (like it's powered off). It used to turn green, but no longer does. Please advise.

SOURCE: power short/ bad fuse?

I had the very same problem. The dreaded blinking power light. I also dabble in electronics. I found that all that was wrong with mine was one bad cap. There are two 1000uF(microfarrid) 16V(volt) capacitors in the mid section of the power board, right next to each other. One was bulging on the top. They have an "X" on top. I replaced it with a 1000uF 35V capacitor from Radioshack. They did not have a 16 volt. (Never go down to a lower voltage) The capacitor I got was larger than the old one but I gently moved over the parts around it and got in there. After replacing this one capacitor, which I got for $1.72 tax and all, I plugged it up and no more problems! It works great! I hope this helps someone else.

SOURCE: Sony Dav-C770 blinking standby light product will not function

I had the same problem, red blinking light after owning for several years. I decided to replace the capacitor at C914 to see if it would work, and it did. Apparently that capacitor is prone to failure. Since this seems to be a common problem, I created a web page detailing the repair. Hope it is helpful. Repair cost $1.39 + tax.

SOURCE: Sony HCD-BC150 As soon as I turn it on, it shuts

Change the audio amplifier IC are on short circuit and that´s the cause your device goes to protect mode

SOURCE: my Philips HTS3410D will not

Mine was exhibiting similar problems. It was the electrolytic capacitors in the power supply board.

There are 4 or 5 of them, and between 2001-2005 there was a bad batch of capacitors that came out of the far east, some of these capacitors were inferior quality so they dry out and fail. You can read about them on badcaps.net You can usually tell a failed electrolytic because the top cap puffs out slightly. Mine were actually almost pointy on top.

If you have the dexterity, soldering pencil and time, you can fix it yourself for about $5.00. Be warned that as soon as you open the case, you void the warranty, so if you don't feel comfortable, take it to a professional. Also, My remote is dying, so if someone wants to sell me their remote, let me know.

My sinotec stl-32vn23 standby button doesn't want to work how to fix that?

If the standby button on your Sinotec STL-32VN23 TV isn't functioning, and the red light remains on without changing to blue, it could indicate a power-related issue or a problem with the standby button itself. Here's how to troubleshoot:Confirm the TV is receiving power from a working power source.If available, try using the TV's remote control to turn it on.If the issue persists, unplug the TV from the power source for a few minutes, then plug it back in and attempt to use the standby button again.If the problem still exists, it may be due to a technical fault in the TV's power circuit or with the standby button. In this case, it's advisable to contact a professional technician or the manufacturer's customer support for further diagnostics and potential repairs.

I have a 51inch LG TV and never had a problem I turned it off as normal and then tried to turn it on a while later and nothing I only got a red solid stand-by light it don't flash when press side buttons...

Try following the steps below.
Step 1
Press the power button once. If the TV does not turn on, observe the LED indicator, usually located on the TV's lower front panel. If the LED indicator turned off after you pressed the power button once, it is in standby mode. Press the power button once again to exit standby and turn on the TV.

Step 2
Observe the Standby light if the remote control will not work. If the Standby light stays on, the television is in Standby mode. Press the power button on the television, then try to use the remote.

Step 3
Turn the Energy Saving Switch off, then press the power button. The Energy Saving Switch is located on the rear or side panel on most Sony model TVs. Refer to your TV user manual for the exact location of the switch.

My LG TV red light won't turn on. although the plug fuse and the remote OK

Try manually pressing the power/standby button on the tv (side or bottom) the red light should appear, most modern tv's will turn on simply by pressing the channel up or down on the tv itself.. But unfortunately in most cases, this seems to be an internal surge and needs a professional to inspect..

Hi I just moved plugged in my ps3 the red standby light came on and now nothing it won't even try to turn on what should I do ?

Sorry I had no idea you sent me this message until today. I apologize for the delay. You probably found a solution by now but if you haven't, please try this..

Solution:

  1. With the PS3 in Standby mode (Red light on), press and hold the Start button until you hear a single beep, followed by double beeps.
  2. Connect the controller using USB cable and press the PS button on the controller.
  3. Now, the system restore screen (or whatever they call it) will come up like this

    ps3-system-recovery-screen.jpg

  4. You have several options here for restoring the system, some will unfortunately wipe up all your data, others will make you lose the file naming.
I hope this helps :D

My 40' vivo tv has turned off and won't turn back on but the red stand by light is on??

If the standby light is on and it does not respond, it is most likely to be a problem with the power supply . First try this, unplug and leave the set like that for a few hours. Then plug it back in to see if the tv attempts to turn on when you try to power it up. See if you hear a "click" even if it goes back to standby. Let me know what you found so that I can help you test the power supply board to confirm, if necessary.
