Input button is stuck so the input features blink continuously unless you hold the button down. is this a quick fix? or a cheap fix?

Not sure if you saw Tom's Guide

I unplugged the TV and held the buttons down and it continued to flash. I continued to hold down the two buttons and replugged it in again and it worked. TV back up and working.

Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in.

NOTE:
Anytime the batteryterminal has been disconnected, please initialize the driver's door power windowand front passenger's door power windowafter reconnecting the batteryterminal.

With ignition switchin the "ON" position, do the following:

1. Push down and hold the driver's door power windowswitch to completely open the window.
2. Pull and hold up the driver's door power windowswitch until the window closes.

Continue holding the switch for approximately one second until the switch changes from blinking to a constant illumination.
3. Check for proper operation of the "one-touch open and close" function by fully pushing the switch briefly to the "DOWN" and "UP" positions.

At this time the power window switchfor the passenger's door windowshould be blinking.
4. Push down and hold the passenger's door power windowswitch to completely open the window.
5. Pull and hold up the passenger's door power windowswitch until the window closes.
Continue holding the switch for approximately one second until the switch changes
from blinking to a constant illumination.
6. Check for proper operation of the "one-touch open and close" function by fully pushing the switch briefly to the "DOWN" and "UP" positions.

Reboot the breadmaker's electronics by pressing down continuously on the Start button until you notice a visible and/or audible confirmation, usually within 5 to 10 seconds. Beware: Some models require you press the Select button first to select a mode, then press and hold the Start button to reboot the system.

That should fix it. Hope this helps!

Special Note: Often the + and - Timer Delay buttons are pressed by mistake, delaying Start by up to 12 hours. If you suspect the Timer Delay feature has been engaged accidentally, you'll need to reboot the breadmaker's electronics. You can do this by pressing down on the Start button continuously until you notice a visible and/or audible confirmation, usually within 5 to 10 seconds. Beware: Some models require you press the Select button first to select a mode, then press and hold the Start button to reboot the system.

TRY the self check here, this model may have it.

When green light comes on and goes off, on front of set press and hold both the menu and input buttons for at least five seconds and release both buttons.

Watch the power light, if it has the self check feature it will blink a two digit error code.

The most common is two blinks, two blinks, a pause and then repeat several times.

Let me know if find a error code.

Do the self check it should have: when shuts down and green light goes out: On the front of the set press and hold both input and menu buttons at the same time for at least 5 seconds and then release both.

Power light on set should blink a two digit error code: like 2 blink,2 blink, pause and repeat it at least 5 times total.


Let me know what error code and I will tell you what it means.

Good Day,

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times.
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source)
1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB (NOT SHOWN IN THE SCHEMATIC).

2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT.

3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB.

I hope this was helpful, BIG IRISH.

It seems like you horizontal board and circuit may not be firing up. But, first you should try a different outlet and power strip and see if that resolves the problem. Back in my day the reset button always seem to do the trick , not any more and you may have tried that already.
Are you getting any light blinking? If so, can you tell me if it is blinking slow, fast, or what?
Can you see if it will blink back an error code? It really isn't to hard to do. Press the input and the menu at the same time, and hold them down for about 5 seconds. I'm sure it should have an input button but, you might have to use the power button instead. However, count the blinks and wait for a pause and then count the blinks again. This TV should give a two digit error code. If successful post a comment on what you were able to get.
The horizontal output has a few diodes that may have went bad. Or the DM could have troubles too. Let's pray a surge strip is all that is needed. I'll have to hold up until you respond for now just to see where it will lead us. I'll keep checking to see if you posted a comment so, that we can continue to troubleshoot this problem for you. Hopefully we can solve it fairly quickly.

Have you tried to access the self diagnosis feature by holding in the menu button and the device/input button on the set for five seconds? The led should blink a series of blinks then pause briefly then blink another series of blinks for the 2nd digit let me know what the blink code is an I will assist you.

With power available at the projector and the lamp off (projector off) - hold the input button on and press the power button on and hold for 5 secs. This will reset the lamp timer to zero.

I wish they could have stuck this in the operators manual.

The blinking light on the speaker button means the forward when busy is on. To cancel it- With the handset on-hook dial #12.
Then press your own station number. Then dial # again. The speaker button should stop flickering.
Note: If the SPK button continues to flicker, Forward all is activated. It is the same process as above but use #11 instead of #12
