hi, im working on a Philips tv that works good, mainboard good, backlight good but the side board that control the lcd panel don't work good, in first time it only worked when I touched the board in a specific point that was very hot, I think it was a short-circuit and when I touched it my hand worked like dissipator, I had found that the source was a resistance so when I eliminate it there wasn't a short-circuit anymore but still without image only color lines when I touch the new resistance wit a metalic thing and it sparks, where can be the problem? lasts image are a close up of the board(ins't the one that is broken, that's first photo)

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

by m1ch43lzmHi, 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... -

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....-

Could someone tell me how to make this Philips TV source work without the mainboard being connected? The model of the board is EAX65423701 (2.1) and the model of the Philips TV is 40PFH40009/88.
The TV is dead, there is no standby light, however there is a voltage of 12v on the pins ( included 12v VAU ) and 3.2v on the PS-ON pin (see photo) when the power board is connected to the main board. If I disconnect both boards I only get 8 volts on 12v pins. I would like to rule out a fault in the main board by making it work, but so far no one has been able to tell... -
by CornitoHello Team,
New issue on LCD panel where I need to find out the cause and the potential solution.
This is on the Philips 50PUH6400, the LCD panel is an INNOLUX V500dk2 xrs1.
I have image, on the right side, the image is more or less normal even if there is a small blur on edge, on the left there is an issue.
When moving up and down in the menu on the right the image is slow to disappear, and is darker, like red/brown.
I've checked voltages, no issue found comparing right and left side of the panel driver.
