Does this TV overheat and fail if installed in a cabinet with no cooling system? Can the boards burn out?

There can be many causes of overheating, not eh least of which would be a malfunction of the device electronics. But first, check these things to ensure best operation:

1. DO NOT install in an enclosed AV cabinet. While these thing look nice and pretty, they do not allow proper air flow to these higher-powered devices and can cause them to run hot.

2. Verify that the rear cooling fan(s) are operational. If the heat cannot be removed from the case, it only stands to reason that the unit may overheat. Replace fans that are non-operational.

3. Clean, clean, clean. Dirt and dust are the enemy of electronics. Many home theater systems are low-to-the floor- cabinets that the LCD TV sits on, and this places the electronics near to the floor where the most dust and dirt are kicked up. This gets into the electronics and clings to the components via static charges. This insulates the components and causes heat buildup. Use a can of compressed air (available at most stores that sell electronics), and blow out the air passages. If the cabinet is extremely dirty, and you fell capable, you can unplug the unit, open the cover, and blow out the dirt that way. Use only electronics cleaner canned dust remover, as it is non-conductive and relatively static free. Using a home air compressor can cause moisture to get on the boards and can create large static charges that can damage components.

Could be a multitude of causes. Here are a few common ones.

Igniter electrode dirty or corroded.
Igniter misaligned.
Failed circuit board.
No power to furnace.
Time delay switch defective.
Sail switch defective.
Overheat switch open/defective.
LP gas valve not opening. Check electrical connections before replacing valve.
Failed to purge system after storage. Light the stove and let it burn for a minute.
Manual LP valve (close to furnace) not opened.
Valve on main LP tank not open.
LP tank empty.

The cable or cutting head may be damaged. The power connections may be loose, an internal circuit breaker may have failed. If the cooling fan does not come on, check the wiring in the cabinet for damaged wires. Disconnect fan wires- noting where each connected and check to see if the fan burned out- if it did, replace the fan and it chould begin to work correctly. If the fan checks out okay- it will have 2 discrete sets of windings-one for the fan, the other to provide control voltage.Check that board with the rectifiers as a rectifier may have failed or there may be a fuse on the board.

If it were mine, I would check everything under the cabinet after it has been thoroughly blown clean.

You are going to make the system overheat and possibly fail with excessive heat. If it's possible, at least run with the doors to your cabinet open and/or, maybe you could cut a hole in the back of the cabinet for ventilation either just by making a hole(s) and/or installing a fan. The circuit boards will afil over time, with age but, you will greatly age your unit with excessive heat.

The reason for this error is Overheat! Please replace the CPU Fan with a new one and add additional Fan for the CPU Cabinet in order to cool the CPU. Then, reset the BIOS to default value by pressing the F2 Key or Delete Key at the Startup and select Load Optmized Defaults or Load Fail Safe Defaults option. This should resolve the issue.

Now the tv is turn on.Any LED power light indication on the LCD panel flashes at all or no light,nothing at all?Yes,than the power supply board it dead.That the board where the power a/c plug into it.But the Tuner board,that the board where the coalax cable brocast signal plug into,might also burn too.Tries websites like Shopjimmy.com,Ebay.com to buy the refurbish power supply board for the replacement and the refurbish Tuner board also.

HI, this may be as simple as a failed cooling fan or, the power board may be experiencing some issues with vital component breakdown as well. i recommend, if possible, to check the operational value of the cooling fans that are located inside the chassis near the power sector. test the value of the fan motor to confirm proper current flow. if no voltage is supplied, this will confirm a damaged power sector(board). if the voltage is present and the motor is not rotating, this will confirm a burned out cooling fan.

Replace the failed device.

**Most common issue here will be a weak or damaged power sector.

hi. the cooling assembly has failed to cool the power board. this has allowed this board to become extremely hot, therefore, burning up the circuits on this particular board. replacing this power board and repairing the cooling assembly and fan, will fix the unit.
