Philips Television: Philips Logo Flashes, Then Turns Off

Fri, 14 Aug 2026 05:44:04 -0700

Philips 75PFL5603/F7 flashes logo on screen then completely shuts off. Voltages on power board are correct when plugged in. The only sign of life on the main board is the red light in the digital audio optical port. The red light stays on for about 5 seconds when pressing the power button, but eventually turns off. There are no other standby lights that I can see. Research on the matter has brought up a possible main board fault or maybe bad backlight cuasing the lights to go to 100% very quickly and overheating and the TV going into protection mode and turning off. Has anyone seen this problem before? I'm trying to determine what parts I need to get to fix it.

I have a Curtis LED1337A that doesn't work and I want to use its screen to make a PC monitor from scratch. Could I just plug it in to a monitor motherboard and grab the other monitor components to make one?

Edit: This is my screen model if that helps

Vizio Television: Vizio P75-F1 TV shows logo then goes black. Repair help?

Sat, 08 Aug 2026 22:40:20 -0700

I have a Vizio P75-F1 with the infamous black screen of death.

The TV powers up, shows the Vizio logo like normal. Then the picture goes black, but the backlight remains on.

When doing a factory reset, (Hold Vol Down + Input for 10 sec, release Vol Down and continue to hold Input). The TV will reboot multiple times, but nothing changes.

This has happened a few times since I got the TV, but always managed to snap out of it relatively quickly until now.

Been at this several weeks now. On my 3rd replacement Main Board.

First one showed the Vizio logo, then went black, but unlike the original, the backlight turned off.

Second was totally dead. Couldn't even get the logo to display.

Third board acted exactly like the original board. (Vizio logo, goes black, backlight stays on.)

Two replacement Power boards don't seem to have any effect.

A replacement T-Con board didn't seem to have any effect either.

I have not replaced the LED driver board, as the Flashlight test reveals nothing. And I know the panel is good, as the Vizio logo is displayed normally when the TV first boots. And yes, I did mix and match several of those boards before sending them back.

Do you have anything you can suggest? I have a multimeter, but I admit I'm not very familiar with checking voltages. Things like knowing what setting I should set the multimeter to, and what spots to check would be great to know. Pictures would be a bonus.

EDIT: I ended up buying a whole new set of boards (Power board, T-Con, LED Driver, and Main board) on ShopJimmy with zero luck. Same thing. Again, when it powers up, the logo comes up fine. Backlight too. So I'm sure the panel is fine. But I've literally replaced everything else, and I have NO IDEA what else it could be. There's no way I got that many dud boards. Please help!

EDIT 2: Tried reinstalling the firmware, but it never seems to get the point that it's reading the data off the USB drive.

Vizio Television: Tv powers on and flashes logo then goes dark

Fri, 07 Aug 2026 19:10:04 -0700

I've read on here that this is a backlight issue but im not sure how to solve it. My Vizio is a V505-J09. Ive tried the common things like power cycling it and leaving it unplugged for a while and those didn't work. Different guides have said this could be a power board issue or a capacitor issue.

I know nothing about circuts or anything but i do have a soldering iron so im willing to try. I could use some guidance on what im doing here though as this stuff is pretty alien to me

Below are pics of the power board, with a front and back of it as well as a close up of what I think are the capacitors for the backlight.
