I suggest contacting sellers on Amazon.com and Ebay.com and offer to pay for a copy of the manual from 2004.

What is a Sandia remote control?

Cannot find any reference to this make?

Send it to an LG Service Centre. The picture you might be able to fix, but not the zero sound issue.

Go to settings, wifi, enter username and password, connect to wifi.

Probably backlights blown or T-con board faulty!

No signal from wherever you get your signal from? That sounds like a test screen.

Unplug it from the mains for 2 minutes. If it doesn't come back on, you need a service call.

Most have a limited number of times you can change before it stays in one region for good.

Unfortunately, televisions are not supposed to be used as computer monitors, newer Smart, perhaps, but not older ones.. It's broken, so you need to take it to an LG Service Centre. Trying to fix yourself always ends in tears, frustration and wasted money.

Or

Buy a 50" 4K Computer monitor :>)

Disconnect for the mains supply for 5 minutes. Plus back in and switch on from the set, not the remote. Does it work, Yes, great, you fixed it.

No? Take it into an LG Service Centre. They have the thousands of dollars of test equipment that is needed.

If you try to fix it yourself, it will all end in tears.

Transistors don't or rarely blow (overheat) for no reason and when one or more does fail it is best to assume it has done so because of an overload condition which can be caused by the current demand of subsequent circuits being too high or the bias being incorrect.

With the modern trend of DC coupling the various stages of a circuit, the bias or quiescent current and circuit gain is set by the component choice and circuit design, the bias for all stages ultimately being controlled by the adjustment of the first stage.

Age and environment causes many components to change value, not the least those components that set the bias. When this happens the quiescent current of the final stages can increase and cause heating.

When replacing a transistor it is important to realise the gain of the replacement is probably different to the original and so certain component values will need to be adjusted so the original performance is restored to the circuit and the transistor parameters aren't exceeded, finishing by checking and adjusting the quiescent current.

Backlight issues, either the led backlights or the T-con board.

The problem is most likely in the power supply unit. There are components in it that have fixed lifespan. These components can be tested if you have the proper equipment, Due to the age of the unit and the fact that they are obsolete due to the new LED designs, you wont be able to buy the whole power supply.

Take the player to an audio visual repair shop.

Never, ever try to fix your own television. Here is a cautionary tale that we see here all the time. I guarantee you 100% that you won't fix it no mater how much advice you can get off the internet! Either buy a new one or take it to a repair shop.

This explains why, and why you can't diagnose television problems on an online forum. The television sections are really only for help with manuals and remote codes.

Here are similar questions that we see often.
Question:

I've replaced everything in my television because it previously had a black screen with no lighting. Now it doesn't turn on at all and all I have is audio. What could be the cause ? Or

Turns on and sound works fine, but the picture is distorted (solarized? polarized? not sure what the term is) I replaced the main board, but that didn't fix it.
Or

I have an LG 55LM6200-UE with a dim lower-left. I just replaced both LED strips with no resolution. There is no physical obstruction visible, so this has to be a cable or board problem, right?

So your television stops working properly and you think it must be easy to fix, because you can buy boards on eBay, and you can watch YouTube videos. So you make a decision, you buy a board and you fit it, but the television still doesn't work as it should! This is a classic case of the 'let's try replacing this' method of television repair and illustrates why it is a bad idea. It doesn't work for a number of reasons. To correctly diagnose issues, you need to know every board, what it does and every component on the board. You need to know which part has failed, replace the component, or replace the board. The parts you purchased off eBay were probably out of scrapped sets and not tested. The part you put in was dead when you put it in, so you just moved on to another guess at what might be the cause and replace a board that is fine. And so it goes on, you change all the boards and it still doesn't work. Did you notice the large print that says 'NO Refunds, NO Returns'. This is to stop you sending your old one back and saying it didn't work, but the unscrupulous sellers use it as an excuse to get money for selling items that may, or may not work! The course to be a television engineer is 2 years full time education, take it to someone that knows how to diagnose and fix. It is by far the cheapest option. The part that failed might be a 20 cents fuse diode hard soldered to a board. They will charge you $5 in parts and a couple of hours labour. It's not the fix you want to hear, but it is the best advice.
