Question about LG Televison & Video

1 Answer

I picked up an LG 65SK8000PUA from scrap that I would like to repair for my new house. The TV only loads the splash screen. Nothing else happens. What would cause this?

It was thrown out for a reason, and probably because it is uneconomical to repair. Take to a repairer for a quotation to fix it.

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.

Testimonial: "Hi Andrew. There seems to be an undertone of aggravation here. I'm sorry you feel this way. Hopefully the rest of the day will get better. Yes, the TV was discarded because it didn't work and I'm trying to diagnose what's going wrong with it. I'm sure my degree in Electrical Engineering and 6 years of engineering work with controllers (PLCs and embedded devices) will come in handy. I've never dipped into displays and I thought it would be a good project to tinker around because we're all cooped up right now. I was just looking for a starting point. I was directed here by another website as a place to start for asking questions. But my initial interaction is appearing to be disheartening. Would you happen to have the manuals for the LG 65SK8000PUA?"

    No not at all Daniel. I have seem so many poor people here on Fixya so utterly frustrated and fed up after trying to repair their own televisions, that I compiled that reply about a year ago. I don't use it that often because it does tend to cause offence and more frustration. I have re-written it a few times to try to improve it. MOST people don't have the knowledge or the test equipment so they blindly pay for, and change each board until they have changed them all. At the end, they often still have a non functioning set $500 later.

    That is quite the set you have and it would certainly be a welcome addition if you can get it running.

    Here is the specs page and the operating manual. I will see if I can find a Service Manual.

    As you get the splash screen, try reinstalling software and drivers which is on the page in the link. Might be just a glitch in the OS.

My dell insprion 1520 wont go past boot screen it stars then goes to a black screen that says start up repair or start windows normally but when i click star up repair nothing happens then i pick start...


Place your windows cd/dvd in the tray and boot to the cd. When asked if you want to install windows, there will be a repair option further down towards teh bottom, or you will be asked to click R like before. The repair only works if the cd is in the tray.

Hi.42" lg plasma tv , i cracked the screen. can this be repaired?


Bad news.. you might as well go get a replacement TV. You can have it repaired using a TV Repair guy but often it costs as much as a brand new LCD. My daughter broke my $1,600 LCD. It would have cost $1,200 to fix.. so I just bought a new one.After that I picked up a TV screen protector called TV Armor http://www.tv-armor.com Its designed to protect the TV from damage. Now I dont have to worry anymore when she is playing near it. It works really well.

Acer 1716 seems to start but will not pick up signal from OS


There probably is an error in the hard drive, since its not booting up. I would replace the hard drive, or take it to your local computer repair shop. I hope this helps!

SCREEN FOR LG 42PX5D 42 in.


I have dealt with Lg in the past regarding screens and they are unable to sell them as a spare as they are so expensive, they are only used in production and a complete new HD TV is cheaper to buy than a screen. for example LG37LP1D £900.00, a replacement screen £1500.00
