Remove that cap.
Zero ohms out of circuit = Most likely the cause.

Re: Vizio VP503 HDTV10a Black Screen
Tom66; I think I really stepped in it this time. The C2 board arrived today. Installed it and within a millisecond, a puff of smoke after power button on. Burnt the same 2 resistors again. I'm posting 2 pics. If you will, please look at them and tell me where to check, and how, for this over voltage or short. I have Photoshop so I can break the .jpg into sections if you need it.

Re: Vizio VP503 HDTV10a Black Screen
The only way those resistors would burn a second time is if the panel is bad.

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... -
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.

Hey guys I've got a MSI GS66 Stealth 11ue-007us Board Number MS-16V41 VER.1 with a broken screen connector on the motherboard.I was wondering how I would go about finding a exact replacement for it.I can't seem to find any schematics that would help me so I'm kinda stumped.I did buy a screen connector that I thought was close enough but it doesn't really invoke much confidence in me that it works perfectly as plugging the screen into sometimes does output a "glitchy" image for just a few seconds.So now I'm kinda in a cross road where I'm pretty sure it could be a faulty screen but I...

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hi I am new to this kind of repairs but I want to learn..I have a Samsung UN65JS8500F. the TV used to work and I tried to fix darker areas in the middle only ( img 1,2,3). I thought the led strip were bad..not the case. I did not research in advance what kind and where the LED were located. In this model they are located vertically on right and left side. Took the TV apart and put it back together. Now the tv shows no welcome screen and no sound is available thru the speakers. ..just a black screen..Backlight LED do turn on...also noticed a 5 blink code , not sure if that was there before. I can...
