SOURCE: CRACK LCD TV SCREEN

I had one broken a few months ago. I got a couple quotes.. it was about $200 less then a brand new one. I'd just buy a new one.
For the new TV I'd pickup a screen protector for it. My son threw a toy at my TV the other day and I nearly had a heart attack from the flashbacks. Thank God I picked up one of these a few weeks earlier. It stopped it. LCD screens really break easily as you know. http://www.tv-armor.com

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: how hard it is to replace by yourself main board Samsung LN-T4065

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

No Picture/No Sound issue is either related to a power supply or main board issue. I'm willing to guess main board, it's where the video and audio signals are generated!

Purchased a 42-Screen "flickers"


Inverter Board going bad or loose plug, then the backlight board will fail within 3-4 weeks later. Good thing you saved a few hundred on the x-warranty, BB won't do a damned thing for you regardless; it's discontinued & they lie about their 'replacement vouchers'.
A 12" bi-metal blade is recommended for your reciprocating saw so that you can cut this thing into small enough pieces for your trash collection.

Backlighting issues on tv set (I think). Screen goes extremely dark after about 30 min. of viewing. Does not return to orginial brightness unless unit is left off for a long period of time


Lcd tv sets are lit by small glass florescent tubes called cold cathodes and, are powered by: ballasts called inverters... these go out just like your office florescent lighting the parts can be purchased online from electronic parts houses and, are easily replaced

It was working fine then no picture dark sceen sound work fine


More information is required. Your backlight is lit (screen not dark) but I need to know what you have connected to the TV (your sources) and how they are connected. Does the menu/OSD (on screen display) work?

I believe your backlight went out. LCD tvs have backlights that produce the picture. A hdtv technician can probably replace it.
