Goldstar Room A/C Mdel BG5200ER when powering up, control panel lights up, then power goes off after 1 or 2 seconds. Looking for reset button, can't find it.

Hello Jeff;
If the TV does not turn on or off, does not respond to the remote
control or the control panel buttons, or has audio but no video:
1.) Press and hold the POWER button on the control panel for ten seconds. The TV will turn off.
2.) Power on the TV and the green LED will flash quickly for about one minute. The changes you made most recently, before using SYSTEM RESET, may be lost.

If the TV does not respond to the remote control or to the control-panel buttons and TV will not power on or off.
• Unplug the AC power cord for 10 seconds.
• Press and hold the POWER button on the control panel for 10
seconds to perform a system reset.

If the TV turned itself off and the light on the front panel started to flash:
• Momentary power fluctuation can cause the TV to turn off to prevent damage. Wait for the green light to stop flashing and turn the TV on again.
• If the TV does not stay on, press the POWER button on the
control panel for ten seconds to perform a System Reset. If this happens frequently, obtain an AC line power conditioner/surge protector.
• An unusual digital signal may have been received, triggering a
protection circuit. Wait for the light to stop flashing and turn TV
on.

If the TV will not power off, press the POWER button on the control panel for ten seconds to perform a System Reset.

I would not recommend using compressed air or any other method that would blow dust around- since the dust could make its way into the set's circuitry via the grille or vents and cause problems. Use a vacuum cleaner with a brush attachment instead.

The only reason to call the phone company is if you're not getting a dial tone on that line. Otherwise, have you shut down the printer and tried to reset it to factory defaults. To do that, follow the instructions below:

• 1 Switch the Canon MX310 off using the "Power" button, then push the "Stop/Reset" button on the control panel. Hold the button down for about five seconds.
• 2 Push the "Power" button while holding "Stop/Reset." Hold down both buttons for five seconds.
• 3 Release "Stop/Reset" while holding down the "Power" button.
• 4 Push "Stop/Reset" twice while continuing to hold the "Power" button. Release the "Power" button. The power light will turn green.
• 5 Once the light is steady green, push "Stop/Reset." Wait about three seconds and push it again. Wait three more seconds and push it one final time, for a total of three times. The power light will turn orange.
• 6 Push the "Power" button, then lift the MX310 cover open.
• 7 Remove both ink cartridges and wait 10 seconds. Replace the cartridges and close the MX310 cover. Wait 30 seconds.
• 8 Push the "Power" button. Wait a few seconds to allow the printer to fully power down, then switch the Canon MX310 back on using the "Power" button.
• Good Luck Mark

Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

If nothing of these works and you still see the error you should take your printer to support service for repairing the parts.

Press the Power Freeze and the Power Cool button at the same time. Hold for 10 seconds and the digital panel reset.

This sounds like a filter problem or a dirty evaporator. Open the fron panel and see if the pre filter, filter, and or evaporator are dirty.

Measure the temp of the air blowing out. It should be 20 degrees lower than the intake air at the filter. If not, we need to dig deeper.
