Hello all, I have LG plasma tv with no picture. What I've found so far is that the 5v going into the control board was not present. I suspect the y board is bad but wanting to know if can be trace to a component.

Re: LG 42PQ30 no picture
Yes all the voltage reads correct. I did find the 5v going to the control board. I did notice the led d201 was not blinking or lite on the control board. Control board???Comment

If all the voltages are there then the control board should be working so yes it could be a control board fault.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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

by howardc64All left and right refers to looking from rear of TV (or looking from front with TV upside down)
- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

by redoxyI am looking at the option of replacing my control/driver board to one with HDMI and/or Display port input on a 2K LED (I think IPS) screen.
The display is Samsung LTM270DL07.
I have tried using the model number to search for a compatible control/driver board but so far my efforts have been futile.
I am looking for inputs on what board could potentially be used for my display.
Attached are pictures of the display label information and connectors (CON30 CON40 only) and pictures of the current control board.
Also attached is a technical...-
