You reports that you've changed the T'Con board. Where is the T'Con board to a Plasma TV? There is no such board to any plasmas. Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. You can also click the [Home] tab to see the latest updates. It will make search easy. There are more than 1350 posts to different brand TVs now.

SOURCE: Samsung 46" LCD TV stops responding

Ok, There are well three boards in this set that would influence such a behavior. The culprit is the Key Pad Board. It has what is called a leaky switch. This then locks up the Microprocessor. This will result in the set operating like a ghost has the remote.

best regards

Lg 42" tv not displaying screen image


The t-con board controls the picture. To test it shine a flash light on the screen abd see if you can see an image when the TV is on. If you do then the T-con board is OK. Look at the back light ballast board (sometimes is part of the power supply board) If you see no movement or a dim picture with the flash light, then the T-con board is gone.

Toshiba 42wh38b Projection TV won't come out of standby


That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

Thanks for using fixya...

Soniq tv manuals


I have fixed 2 soniq tvs that were stuck in standby ie would not turn on via the power switch or remote.
One of them would turn on briefly and then turn off again while the other just refused to even try to turn on.
I thought it was a problem with either the power board or the main board but it was not.
The control board was detecting a problem and was shutting down power board.

The fault with both of them was that the LVDS cable that connects the main board to the T-Con board had poor contacts with the sockets it is plugged into.
Solution was to CAREFULLY unplug the cable at both sockets..don't pull it by the cable or you may disconnect a wire within the cable... and give the pins on the sockets a little spray of electrical contact cleaner then refit the cable securely...make sure it is pushed fully into the sockets.

Picture on my Toshiba 37RV753B has gone off and the standby light keeps flashing yellow. It was working ok a few hours ago, but I switched it off to go out and now it won't work. It's only just over a


Hello!
If you have used your TV 24/7 for the past year, the issue might be in the power supply. If there are "bloated" capacitors, set will not start up. If you haven't unplug it for a year, it might be staying alive. Once you unplugged the set, those capacitors won't let your set back to normal. That's a big project and requires technical background. If you think you can handle that, open your TV set and inspect TV's power supply board. It will be located near power cord plug or wire. Also, it might be covered by tin shield, which must be removed for further observation. If you see any "bloated" electrolytic capacitors, replace them with same value and voltage. But it might be main board's issue, as well. what is your place's ambient temperature? If it's lower, than 75F, try to warm up the back of the set, before even trying to poke it open. Use hair dryer. First, point it on main board's in/out connectors. Do not overheat! Few minutes might be enough. Then, try to plug the set in and observe the behavior. Any change? turns on? Main board is bad. Same with power supply. If heating up main board area does nothing, try power supply area. If it makes a difference, start looking for bad capacitors.
Good luck,
Let me know results.
Thanks,
Alex.

37PF9731D/10 - when turned on the tv power light remains green but no picture or sound. Just a clicking sound - like it does normally when swiching on from being on standbay. It reapts the attempt to turn...


The clicking sound is from the main power supply relay being turning on and off, it is driven by hte main board and it gets the power from the standby power supply board.
You need to check the main powwer supply board and the standby power supply board voltages.
Check the resistor in the main power supply board also

Samsung LN-T2632H won't turn on.


Follow these steps to figure out what problem is.
When you turn on TV, look at the back and see if the back light on. If it is on, the power supply and inverter work fine. The suspection now is main board and T-con board (the small board on the middle-top of the panel)
To find the problem from the main board or not. Look at the power supply and measure Vs on - turn on the TV, this approx 5 vlt DC needs constant once you turn on the TV. If it is drop or unstable - main board problem - replace it.
If Vs on is good - disconnect the T-con cable from the power sup. If power sup stop clicking - T-con need replacing. Hope it help.
