The problem i have found after changing the Tcon board is the display here is how to check.
1. open television
2.remove cover from Tcon board
3. re-secure Tcon without cover.
4. plug in talevision and check ic at upper right of tcon has two caps above it.
5. when you apply power the tv cpu will check all circuits pin 4 goes to ground and ic should switch on if there is no excessive load at pin 5 to 8. which feeds the display the voltage at that point is 15 volts dc to ground.

if it not present then display bad.
also to further verify unplug two connections to panel the supply should apear at pin 5 to 8.

Unfortunately, if LCD panel is broken it can't be fixed. It has to be replaced, which not economical.

If the LCD Display is broke, only replacing the LCD Panel will fix it. The Main problem is that the cost of doing this would exceed the cost to replace the whole unit. I am sorry about the bad news.

Thin blue line down middle of screen


The red line driver at that point isn't working or there is a bad connection to the panel for that line. (I assume the intensity and hue of the cyan line varies witht the picture). What type of screen is it? Plasma or LCD? The following is for LCDs and may not apply to plasma panels. (I haven't had to fix those yet.)

Once in a while you can solve the problem on an LCD by gently massaging the connector to the display panel edge at the bad spot, although there is a risk of causing other lines to drop out. I once fixed an LCD that had a hair caught between the elastomeric connector and the display glass, but if that were the culprit in your case, you'd probably be missing more than one line. It could also be a problem with the driver chip for that line.

Be very careful about tearing into the LCD. The connections are very delicate, the fluorescent backlight tubes are glass and have mercury inside, and the potential for electrostatic discharge damage is always a concern. It's easy to cause more problems than you fix when you get into the connections, although those can usually be reversed with patience and steady hands. The worst case is a misalignment that would mess up your color registration (color drive going to the wrong line). Most panels have a sticker inside warning against removing the driver electronics. It's there for a good reason.

If I've scared you off, or if the connector massage doesn't work, there are companies like Moniserv that specialize in repairing LCDs. They have the equipment and dust-free facilities needed to repair bad panel drivers.

Have several problems with either a bad LVDS cable from Main unit to the LCD controll bd. Sometimes the cable is just not connected properly. If you reseat this cable and the problem still exists you most likely have a bad LCD control bd.
