i have a toshiba 50l1350u that wouldnt power on regularly without unplugging it and repetitively trying over and over.. when it powers on its good till it shuts off. i updated the firmware and didnt have a problem with it for a few months.. then it started happening more and more.. i bought the PK101W0100I Power Supply Board Unit to fix this and it is doing the same thing.. all that ive read is the power regulator is shot or one of the fuses is shot but the power board was supposed to replace all that.. unless i bought a bad board im at a loss.. is there anything on the main board that can be doing this? im not a EE and cant replace anything with unsoldering it.. need any advise..

Re: toshiba 50l1350u wont turn on
Try reinstalling the firmware. Maybe you have an EEPROM which is losing data over time.Willing to help but I'm no expert.Comment

Re: toshiba 50l1350u wont turn on
Anyone has a cheaper source than this mega-expensive ebay seller?

Chip costs probably less than a buck...

Re: toshiba 50l1350u wont turn on
You don't mention the markings on the EPROM but the cheap CH341A programmer has read all for me so far.
Blank EEPROMs are available on ebay or Ali, perhaps the seller will sell you just the dump via email that you could program yourself if you can't find a dump.
You could try using freeze spray to aid in reading the one you have already, there are instances this will work, but no guarantee.Comment

Re: toshiba 50l1350u wont turn on
Finding the eeprom dump might be a major task. maybe 14 bucks isn't so bad.

Hello, HP laptop model 15-EU0005NA. It does not turn on, 1 in 100 manages to turn it on then after a while it freezes/disappears/flashes, etc.
After removing the motherboard and connecting the board with RAM to the power supply, I noticed that at first all voltages start correctly and after a few seconds 3.3V on the PL4501 coil disappears and somewhere in this area something starts beeping on the board, sometimes after touching it with a finger in the area of PL4551 it stops beeping and 3.3V appears again.
Original HP 150W power supply, the diode in the power socket lights... -

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?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.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...
