Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

reseat the LVDS cable inside the unit. this is the cable from the main board to the panel. if the problem is still there then replace the main board 1st, part # BN94-00629F. if the problem is still there then the panel is bad, part # BN07-00245A. if you are not familar with TV repair have a tech repair this for you, if it is under warranty call the manufacturer for nearest repair place.

Hi. You can try to go into service mode and reset the LCDTV to Factory Default. This will clear out all buffer over run's and any software related issues. It may fix the problem or it may not. If this doesnt fix the problem than you need to have a qualified Technician to look at it. The problem is in the AV circuit board, a technician who is qualified to repair electronics at circuit board level should be able to repair this problem rather quickly and inexpensively. Most technicians who do not have the expertise in repairing cicuit boards to component level would rather replace the whole AV board than repair it and this will be rather expensive.So talk to the repair shop before you drop the TV off.

Be very careful when accessing service mode. I suggest to write down all information in all areas before proceeding to a factory reset. If you do not record all values correclty you run the chance of not being able to use the TV again. To go into Factory Service mode, use the original remote and in this sequence push POWER OFF-MUTE-1-8-2-Power ON, the set will turn on and enter service mode, if you hit all previous keys correctly. If it doesnt try again. When you are done hit POWER OFF and this will exit service mode and save the data.

SOURCE: Trying to hook compaq presario laptop to philips lcd digital tv

hey fox,
sounds to me like a connection problem. If the compaqs output is vga, you need to convert the input (tv side ) to hdmi, component, s-vidio... what ever you can find. Typically when you hook up your computer to a flat screen or such, its best to try to use the hdmi ports or the rpg. But if thats not available you need to take the outout from your laptop ( whatever type that might be and input it into your flat screen tv. If you input laptop into tv under ( eg..HDMI) then when you VIEW it you need to select the correct source on your flat screen. Such as hdmi or pcmi or rpg.I know that the do sell alot of cables that adapt from one type of connection to another. Typically only one cable is required from the laptop to the flat screen. If you think about it you are only using the flat screen as a monitor.

SOURCE: Samsung LNS2641D 26-Inch LCD HDTV lost its picture

Since you have sound on the stations this is a problem in the display. Take bright flashlight and hold it against the screen. Look for an image around the edge of the flashlight. If you see an image then its one of three problems;
1) The inverter board is bad.
2) The CCFT (cold cathode fluoresent light) are bad.
3) The power supply to the inverter board is bad.
Someone knowledgeable in electronics can replace the bad part(s).

Samsung 46" LCD LN46B650 started showing vertical


had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

Sadly, the screen is the most expensive part of the TV. The replacement screen would cost more than the TV is worth. Shopjimmy.com is the only affordable place to buy the replacement screen, But, they are out of stock. Usually, the screen cost around $250 to $350. Any other website will cost an arm and a leg. Buying a new TV would be best at this point.
