It sounds like you have already done some troubleshooting by replacing the TCON and main boards, but you are still encountering issues with the TV being stuck in burn mode. Here are some additional steps you can try: Power cycle the TV: Turn off the TV and unplug it from the power source for a few minutes, then plug it back in and turn it on again. Check the cables: Make sure all cables, including the HDMI and power cables, are securely connected to the TV and any external devices. Reset the TV: Look for a "reset" or "factory reset" option in the TV's menu settings. This will restore the TV to its default settings and may help resolve the issue. Contact the manufacturer: If none of the above steps work, you may need to contact the manufacturer for further assistance. They may have additional troubleshooting steps or be able to repair or replace the TV if it is still under warranty. Hopefully, one of these steps will help resolve the issue with your TV being stuck in burn mode.

There are several possible reasons why an Instant Pot might go into "burn" mode:

1. The pot is empty: The Instant Pot is designed to detect when the pot is empty and will go into "burn" mode to prevent the heating element from burning out.
2. The pot is too dry: If the pot is too dry, the Instant Pot may go into "burn" mode to prevent the food from burning.
3. The pot is too full: If the pot is too full, the Instant Pot may go into "burn" mode to prevent the food from boiling over and causing a mess.
4. The pot is dirty: If the pot is dirty, food particles or debris may be stuck to the bottom, which could cause the Instant Pot to go into "burn" mode.
5. The Instant Pot is malfunctioning: In rare cases, the Instant Pot may malfunction and go into "burn" mode even when it is not supposed to. If this occurs, you may need to contact the manufacturer for assistance.

If your Instant Pot goes into "burn" mode, it is important to follow the instructions in the manual for safely addressing the issue. This may involve removing the pot, allowing the Instant Pot to cool down, and cleaning the pot before attempting to use it again.

Do a hard reset to this set, and check. Unplug the TV from AC wall outlet, and re-plug it back after 20 minutes or so. This must make it a hard reset. If it do not help you, you have to enter its service mode option, to release the burn in mode. To get more details, http://electronicshelponline.blogspot.com/

The binding up is normal for 4x4 mode because the parts which normally are bypassed in a 2 wheel mode are locked and rigid in a 4x4 mode. But being stuck in 4x4 mode is not normal.

Some of the units are Vacuum operated, others are electric. The electric units use a single solenoid with a variable length
plunger that gets its signal from the dash knob. When the lightbulb in the dash selector knob burns out; the voltage changes at the solenoid plunger. The plunger then operates differently than how it is set on the knob selector.

For the electric models, you would put a voltmeter on the wire to the 4x4 shift solenoid and have someone move the selector knob to each position and see if the voltage changes.

No, the burning house unlikely cause the problem. The A470 is particularly subject to something called a "stuck shutter". A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help. Now recommend proceeding directly to Fix 5A listed in the article. If that doesn't help, your camera may have a more serious problem of a broken ribbon cable to the shutter. This seems to be very common for the A4XX series cameras from Canon. Here's some info on the problem.

sounds like you have a bad door switch, check all the switches and connectors for burns, if not its the pcb

this may sound weird but I had it work on some buttons such as you have on the blender. Get a pencil and using the eraser end tap firmly on the stuck button hopefully it'll release it.
best to you.

Do the following

Unplug power cord.
Wait two minutes and plug it back.
Keep repeatedly pressing the eject button while you start the unit, before it starts reading cd inside. Do this a couple of times.
If you cannot eject the disk in this way you will need to take unit apart.
Unit won't start until the disk is inside, as it tries to read the disk , disk is faulty and unit get stuck.
