Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.

The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV...

I have a Vizio E550i-A0 that will not power on. It also does not display the standby light in the corner. I disconnected the main board cable to see if the backlights would light but they did not (maybe this is normal for this set?). I checked the voltages on the plug and they all read in mV or 0, so there's no voltage there. The fuses are ok, and the voltages of the 450v caps read about 160v. I see no visual damage on either the power supply or main board. I have read online that the main board is usually the culprit in this model, but not getting backlights with the main disconnected makes me...

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.

Assuming...

hello, �� i have been sitting on some microsoft surface pro 4 tablets for a while now. i was originally tasked with replacing the battery in one of the tablets, and ended breaking the screen and logic board in the process. decided to buy another tablet with the same specs. got that screen off successfully of the second tablet. the logic board appeared good, but i guess i shorted something out in the installation process of the logic which i've read is a common issue if there is no barrier between the logic board and battery pins. all that said, i ate costs of the repair and have...

Hi there,

I've got a 39" LG 39LN540V that's just spontaneously stopped working! The symptoms are - when I plug it in, the red light will flash on twice, then go out, there's no visible picture, and I couldn't see anything using a torch on the panel either. If I press the power button (either remote or on TV), the red light comes on continuously. If I press power again, the red light flashes twice.

The TV is using a power board EAX64905301. I've attached a diagram of the power output, I've tested the voltages with a multimeter and I'm getting the following:
