Top 20 LG 42LC3R 42 in. LCD TV Questions & Answers

the LCD screen has a light source (like a monitor). It can be an lamp (like a projector TV), a mercury tube (like a monitor) or a LED-based lamp (so-called LED TVs have that, not to be mistaken for OLED TVs, where each pixel is a LED). I don't believe this model is an OLED. It could be one of the others, most likely a mercury lamp that lays at one side of the monitor and illuminates the screen. You could shile a flashlight to the screen (from close distance) while the TV is powered on and see if any image is being formed on the LCD. If it does, the lamp is burned out and needs replacing. If no ghostly image is seen, then it could be the video processor and then it's a bigger problem.

LG Zenith recommends replacing the Y-sustain, x-sustain and digital /logic board as a set. After you replace you will need to check the voltages listed on your panel. The cost if bought from second hand dealer like shopjimmy.com will be around 250-300 for the parts.
please leave feedback

you have a screen sepration failure you will need a new panel big buck

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

You can't, the LG DVD Remote is single frequency. If you are lucky, the LG Television Remote, might control an LG DVD. If you have lost a remote, have a read of this https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote ..

It can't be done. The DVD remote will be single frequency for that device only and the LG remote for that LG Blu Ray (or series) only. Companies don't make cross-control between makers easy. The only exception is cable and satellite boxes to allow their remote to also control the television. If you have lost a remote or it doesn't work, this is the answer https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote ..

It appears to be a model made for the India market. https://www.google.com/search?q=lg+dsi+8555+manual This is the only service manual that is related. If the display is not working, look on the back of the display board for a split or bulging electrolytic capacitor.

That will show in your network settings on the tv screen under manual entry network, or automatic entry try both and then write them down when it shows them.

This tv will be so easy to diagnose, a 4th grader with a multi meter could fix it. There are only 3 simple tests to do, for starters make sure the power supply is working, not sure why you would have ordered another board without testing the one you have!! Use frame as ground, push the power button, put red or hot lead of multi meter to pin 8 or 9 on CN 802, you need 12 VDC there, anything from 11.5 to 12.5 is good, if you see that voltage the power board is working, see how easy it is to trouble shoot the power board and I'm guessing it will be ok as this power board almost never gives issues. Next test, on the main board look for the the digital optical audio input jack, take a small screwdriver and push the cover open and you should see a red light inside of it, if you see that the main board is working, this model has some issues with the main board BGA IC need reflowing but the simple test of looking for the red light inside the audio optical jack, now with process of elimination and the fact 90% of LED TV failures are the backlights you have come down to them being bad and needing to be replaced. You will need to remove the frame and the panel to get at the lamps, be VERY careful handling the panel, it's very fragile, there will be a piece of plexi glass and 2 or 3 defuse screens after you get the panel out that need removing, put tape around them and mark the top, as you need to put them back in the same way they came out. Best place to order parts is shopjimmy,com, I looked and they have them in stock for $50 plus shipping. See diagnosing a TV is very simple as long as you know what to look for and in what order to do the various steps needed. What is happening is, you power the set on, see the message at the top come on for a second and go off, the power board has the inverter built into it, when the set is turned on it looks for the proper DC voltage and current draw to the backlights, your current is higher than allowed so the inverter is shut down, resulting in no backlights, and no it's not a fault of the power supply. Good luck!

Totally the wrong way to go about it. Buy a remote that is made for the television, an exact copy of the original. Codes in the link https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote ..
