I have 52 inch LCD TV, about 4 years old. For last 1 month, on the LCD screen, the blue color seems to be spreading. As per the samsung service person, it is either LCD panel or that of T-Con Board. However, as per him T-Con Board cant be purchased independently from samsung, so there is no way but to replace the entire LCD panel. Is there any way to know what would be the part number of the T-COn Board and is it possible to source it elsewhere. Is there no option but to change the panel. Does it make sense to change it or simply buy a new TV.
Here's a place where you can purchase a T-Con board. TV Parts Universal TV Stands DLP Chips ShopJimmy

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

A couple of weeks ago we had the screen broken in our LG LCD TV when one for the kids threw something at the screen. We got a quote to fix it and it was going to cost more to replace the screen than what it would be to buy a brand new TV. We shopped around for a new TV, comparing LCDs and Plasmas. In the end we purchased a new LG Plasma, which had a thin layer of glass over the screen for protection compared to the LCD. We thought this would be much safer with a 4 and 6 year old around the house running amuck. And there seems to be no differfence between the LCD and the Plasma. Hope this help someone's problem.

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

Good fixes. Sometimes the connector for the cables running from the LCD to the T-CON do not make good contact. You might try moving them around to see if it affects the picture. You can even carefully disconnect and reconnect them.
I have come across one person that fixed a display by resoldering as many joints as possible on the main board.
When these boards are made they use a wave solderer and with the new RoHs standards and shoddy workmanship a lot of 'cold joints' are developing. If you do this, use RoHs compliant solder.
