I had this tv for a year and everything worked fine. Just recently it turned off and would not turn back on. When the tv was in working condition the power light would stay on red and when turned on the red light would blind and then turn green. Now that the power will not come on the light stays red. I did some research and that led us to replace the ir sensor board. I hit the power button and the tv came on. (thought I was done) However I shut the tv off and again it would not turn back on. So questioning what I did...I took the new ir sensor out and put the old back in and again the tv turned on but when turned off would not turn on again. Any suggestions?? Thanks

Re: Magnavox 46me313v/f7 will not turn on
From the sound of it unplugging and plugging the tv back in is the trick to get the tv running but you have to do it every time.
Have you tried performing a factory reset on the tv? Have you checked for firmware updates? Honestly it sounds like a bad main, possibly bad EEPROM. What is the part number of the board you replaced and the main board part number?
Taking pictures of the circuit board will almost always help.

Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But... -

I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.
I started on the ACER:
Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.
I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap... -
by robante15Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.
If I remove the... -
