Hi
here the steps

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 open fuses F9A04 and F9A05 part # 283P144080 on the +24 and -24 volt lines. If the fuses are open the convergence output circuit would be suspect. 
2. Shutdown at power with self diagnosis error 
2-1. At power on check for 12-volts DC at connector KH pin 8, if missing check IC9C51 part # 270P990010 and L9C52 part # 441D009020 on the Signal PCB.

    Could be a few things. Bad bulb? Just like anything, some are just not made correctly. Could be the ballast that powers the light, or you may have a component on any board that is failing causing it to go into a protection mode.

    You have to have a Panasonic remote (one that came with the tv, or a similar model), and if it doesn't have the PIP button (or Split-Screen button), then you will have to use the '0' (zero) button.
    Power on the tv, (and wait for the lamp replacement text, and press ok or enter or whatever it tells you to make that go away.) then press and hold the zero button on the REMOTE, and AT THE SAME TIME, press and hold the 'vol -' (volume down) button on the TV.
    Zero button on remote AND
    Volume button on TV AT THE SAME TIME.

    This worked for my PT52LCX16 ( PT-52LCX16 ) which came with a remote without the PIP button.

Was the lamp blown before it was replaced? Is this model 46DL10. Are any lights flashing on the front of the set?

You need to give us the exact model to find the counter reset.

    I did not find any counter reset procedure or free service manual for this model. Here you can get the service manual, I do not know if registration is free. There you should find counter reset procedure, if there is any.

    In any case, ensure that the lamp is placed correctly and that the door is closed properly.

To reset, hold down on-off button and push reset button once.
Keep holding on-off button until display changes.
Release on-off button, and display should blink 12:00

Timer has worked in the past as programed. However, upon resetting timer to correct time of day then setting "ON" & "OFF" porch light seems to come "ON" two hours...


I test timers.
Timers go bad.
EJ351 has 1 year limited warranty.
Wiring is correct or timer would not operate.
Bulb is good.

I would reset timer again and re-program.
If timer still will not function, then timer has gone bad.
Following page has manual:

Reset instructions: Move the control lever to the OFF-CLEAR position for about
20 seconds. The red indicator light will go off and any previous
time settings will be cleared from memory.

My Samsung HLP4663W 46 in was making a buzzing noise for several months. I know it could have been either the fan(s) or the color wheel, but I never opened it up to determine which it was. Now the TV quit...


Great reasoning work! In fact, the lamp will not light if the color wheel does not spin-up. Fans will not stop the process of lamp ignition. Instead, a fan will be detected and a message will appear on the screen telling which fan has stopped. You need to have the color wheel replaced.

Optoma hd65 projector new bulb wont turn on...cant reset timer!


I think it's a lamp driver issue from what I've seen others have gone through. I also read that if you go through the sequence of unplugging, plug back in, wait 20 seconds and try to turn on, multiple times, it will finally kick on and work. I just got mine to turn back on by doing this and waiting through the fan cycling without the light turning on. After the 4th sequence the light flickered. After the 7th sequence it finally turned on and is working. Now I can watch the Super Bowl and will look into replacing soon.

HI, this may be a simple cooling issue. try inspecting the cooling fans that are located near the power sector. if these cooling devices are not operational, they will cause the power board to shut down periodically, due to heat build up.

If the fans are operational, this will confirm a weak and defective power power board.
