My TV no longer has a power button that can manually be pressed (button simply fell off, unsure of the cause of that), and I've had to use the remote to power it on and off for the past year.
Three weeks ago the remote became increasingly unresponsive and took upwards of 100 presses to power up the TV. I assumed this was a problem with the IR sensor on the TV and took it in for repairs.
Repairs cost me $170 and I got the TV back two days ago. They didn't replace the power button on the TV, but it seemed like the remote was once again working. That is, until this morning, when it suddenly is again completely unresponsive.
Power supply looks alright, fuses are all intact. I had a convergence issue, where I had to keep readjusting every few times I turned the TV on, but I'm assuming this is unrelated. Really I want to know what the problem could be. As far as I know, the IR sensor has been replaced. As I said before, my TV was working for two days after repairs and now is again unresponsive. I don't believe it's the remote, as I've tried three different ones (one that came with the TV and two universals which were programmed to it) and I keep getting the same results. The light won't power on or anything. It's as if the set is completely dead.

you must open the remote control for clean the keypads from corrosion , dust, gum, etc use alcohol isopropyl to 80%. If the control is new you must complain to the company that is NOT working and clami another new ones.
Check all the solder terminal at its main power regulator section circuit. Any loose solder terminal can poise this type of problem. Resolder all the suspected solder terminals by applying a little more solder. If you wish to get more details, check this site.
Update firmware (usually every 6 months). Connect the ethernet to the unit, press Net and Power button simultaneously. Hit Enter as directed. Takes up to 60 minutes. OR (if no internet service), download firmware updates onto a USB (32MB) and connect it to the USB port. If you do not update voluntarily, unit will suddenly not feed video.
1) While pressing & holding down the TV POWER button, press CHANNEL UP or CHANNEL DOWN repeatedly until your TV is turned on or off.
2) Release the TV POWER button when your TV is turned on or off.
*Each press of the channel button sends a manufacturer code (1-45) to your TV, one after the other.
Note: You may have to do this every time you change or remove the battery, as the remote will reset itself to the default code.
Please follow the steps below to program your remote control to equipment other then your DISH receiver: Note: If you start this procedure and at any time and do not press a button within 20 seconds, the remote will end the procedure automatically. Simply start over again. Use the TV button for your TV, the VCR button for your VCR or DVD player. These Mode buttons are located at the top of your remote control. 1. With the desired equipment on, press and hold the correct Mode button until all mode button backlights illuminate, then release. 2. Press the numbers 5-0-0 on the remote control. 3. Press the Pound (#) button on the remote. 4. Press and hold the correct Mode button until all mode button backlights illuminate, then release. 5. Press and release the Power button on the remote control. 6. Press the Up button once a second while pointing the remote at the desired equipment. If the code for the equipment comes up, the equipment will power off. 7. Press the Pound (#) button. If the code entered is valid for the remote, the mode light flashes three times. 8. To verify the code works try several different functions for that equipment. We cannot guarantee our remotes will work all other devices. If this does not correct the issue, unfortunately our remote will not work for that device. We apologize for any inconvenience this may cause.

You can perform a manual search.
Press and hold TV,SAT,DVD or VCR until the centre light blinks red.
While it is blinking press 0000
The flashing will speed up.
Press the power button repeatedly - it will cycle through all codes.
When your device turns off (powers off) press the okay button.
It should now power on and off correctly.
Check the other buttons to see if everything works.
If it does not start the process again - it will hit another code which will also power down the device - takes a long time but should work - manual states it may take 20 mins - practise says longer
