My Haier 42EP24S did the same thing 23 days after the warranty expired. I am an Electronic Technician by trade so tried to repair it. I found that the problems was on the YSUS board. The Vs supply line develops a short and causes the 4Amp fuse to open. This is a common problem with this LG made monitor. There are no board level schematics available for this monitor so component level repairs are almost impossible, board replacement only. The YSUS board cost $460 from haier. I complained to Haier America and they replaced my unit with a new HDTV. That was 6 months ago and now the replacement tv is going junk. Good Luck.....

You can Google Replacement TV Screens to get the price. It's a huge job to replace the screen. Every part inside the TV has to come out Then the bezel has to be separated. That requires special tools to prevent marring and scratches. Best left to a pro.
Suggest that you borrow a monitor from someone and try it on your system. If it works , you may have a defective backlight on your monitor , which means that you may want to replace the monitor. If the replacement monitor also is black , you probably have a video output problem , which would require repair of your computer.
Let's see if I understand the problem: when you have a blue screen, you see at least one black vertical line in the center, and when you have other material on the screen the same line(s) is yellow (or conversely, you have a blue vertical line that stays on all the time). If I have parsed your complaint correctly, then you have a bad connection in the LCD panel or a bad LCD column driver chip. It is possible that an expert technician can solve a connection problem by "massaging" the connection or taking it apart and reassembling it, but sometimes this only creates more problems.
Replacing a failed LCD panel driver chip requires specialized equipment. Search for "LCD TAB repair" to find a company with the right tools.
Do you have the tools and equipment necessary to do an electronic repair? These are highly sophisticated devices - not user repairable. If you have the equipment and source for parts then begin with the set's internal power supply and troubleshoot as required. If you do not have the equipment or training do not get into that set. Even the static from your hand touching a circuit board could destroy expensive parts. Call Dell and they'll recommend a local service center.
Without looking at the set and from what you say , it sound like the chroma stage has a fault on it . However sometimes it can be that someone has messed with the settings in the menu and caused this problem so check that first .
If you find they are ok then I am afraid the only solution is an engineers inspection , the chroma chip will almost certainly be surface soldered and these require special equipment to repair them safely ..The other possibility is that if you have a cable or Satelite box attached the fault could be in them and not on your television set :.. it's just not recieveing a picture from them . disconnect them and try you television on its own first ....

You need a T-con Board and I have that one for $80.00.
I reclaim working components for TV damaged in shipping or returned for
other reasons. Simple repair for any body with a Philips screwdriver.
NO special tools needed.
Any part in your set can be replaced. It is a question of cost, and the qualifications of the service person. For this set it is important that only the manufacture service rep work on it. There are specialized tools, training, and setups for performing service on this type of set.
A poping sound is caused by a component actualy rapidly blowing! This should be looked after. Using the set can only create more problems. Components rapidly blow because of a catastrophic short or over-voltage condition of some type.
The manufacture service rep can do a visual inspection of all the circuit boards, and replace the board with the one that shows signs of physical damage. He will then run diagnostics, and perform the proper troubleshooting to find the cause of the problem and replace any other defective parts or circuit boards.
The repairs on these TV sets can be rather expensive. Ask for an estimate before approving any work done. When buying any of these TV sets it is best to take an extended warranty. This is an insurance in case of an expensive failure.
From your description, I would suspect a section of a power supply has failed, and possibly a failure in one of the main driver circuits. This type of repair will not normaly be low in cost.
