Question about Panasonic PT-45LC12 45" Rear Projection HDTV-Ready Television

New Bulb... No Screen...

I just installed a new bulb in my Panasonic PT-45LC12. I plug it in after that and the Power/Stand By button turns red like it is supposed to... I then push the button on... It starts to flash green. The Fan comes on and you can hear a click... I left the unit on several minutes and nothing happens... The green light just continues to blink. Thoughts?

Check for a small device above the lamp, it looks like a resistor...if it goes bad, the tv will not come on. I believe its there to open circuit it case lamp heats above a certain temperature. you need to remove the bottom rear cover to access it...try putting a jumper wire in its place and turn tv on.( just be certain to stand clear of any enerzied parts) and be certain to remove jumper once test is done. This actually worked for me...now i just need a good parts store to find device

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?


Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

TY-LA1001 Timer reset

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

If the electricity sound was loud and static sounding then you had a short with arcing which is not good and you blew a board or the socket that the bulb went into. Check that there is current at the bulb fitting.

Hi,

The most common cause of Panasonic Rear Projection LCD TVs not starting is bulb failure. The PT-60LC13 users manual gives some help in translating the LEDs on the front of the TV.

If the TV worked normally for a period of time (months or years) and won't start, the most likely cause is bulb failure. There is no way to measure the bulb, sometimes the bulb is visibly damaged when it fails. Remove the Lamp Assembly and look at the bulb.

If there was an On-Screen Lamp Replace warning and TV won't start, bulb has failed.

The first step with all Panasonic Rear Projection TV "No Picture" problems is bulb replacement. If that does not remedy the problem, get a technician, there are no user serviceable parts. Guessing if the ballast, power supply, controller board or optical engine is faulty is not practical.

The Panasonic Lamp Gallery shows all Panasonic models and Lamp Numbers. There is also a link to Panasonic DIY bulb and lamp replacement.

szorehkeyhom,

If your unit is more than three years old you probably need a new bulb. Looking at it or even trying to test it with a DVM will not reveal if it is ok or not. It would be better to just replace it if it is more than 3 years old. I have a tip at http://www.fixya.com/support/r4168009-change_lamp_in_dlp_projection_tv which explains where to get a quality lamp at a good price and how to do the repair.

Thanks for using FixYa and for the great rating.

Lamp flickers but fails to go on fully.


Sounds like the lamp but it does depend on how old the lamp is. If it is original just change it depending on total hours of use.

Panasonic LiFi model number PT-50LCZ70. Have red lamp light flashing on front 2 times. Have tried to turn it on and get no picture and no sound at all. I checked and the fan is running. What now?


After the red 2 flashing starts, press the power button on the front of the TV and hold pressed down for ten seconds.
You will hear a faint click comming from the back of set.
After 10 sec release the button and wait 10 more seconds then press the start button and release right away.
The green light flashes and the bulb attempts to start.
I found my picture will turn on on the third attempt of the bulb restarting.

When you do this and the room is dark you can see the bulb attempt to restart, My bulb has restarted on the third restart every time.

(note: The three start attempt happen after I do the button pressing
1 time and I do not need further button pressing restarts.

I think panasonic needs to let us know what the problem is.

I called Panasonic and they told me to plug it into a wall plug by itself.

I have it plugged into a multi plug adaptor now and have not tried this yet.

I was wondering if you could tell me how to reset the timer after I have installed a new lamp. Can you help me? tv is a panasonic pt-56dlx25 Thanks, dave


Plug the power cord back into the properly grounded wall outlet. Then press the POWER button on the projection display or the remote control to turn the power on.

2. While pressing the VOL- button on the projection display, hold down the PIP or SPLIT button on the remote control simultaneosly for more than 5 seconds.

3. Whe the lamp time reset procedure is complete, the screen will display "LAMP TIME WAS RESET TO 0." When the lamp time is reset, the LAMP indicator will go out

My PT-45LC12 has picture and fan problems


More like lamp failure. Could be other things of course but start with the lamp cause it will need it anyway if has been a couple years.
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy. Some models are real bulb hogs though. Look them up on the net (include the word complaint or repair) before you buy, or you might be sorry. Many class action lawsuits out there - even against some of the name brand makers.
Hope ya fix it!

PT-45LC12 wont power up


You have a bad lamp. The "clicking" sound you hear is the ballast (lamp power supply) attempting to start the lamp. The warning on Panasonics that comes up on screen does so when the life expectancy of the lamp is approaching. Otherwise your "clicking" sound and the red light on front are saying bad lamp. When you replace the lamp remeber to follow the instruction that Panasinc provides with the new lamp on restetting the lamp timer. This is usually done with the volume down on the TV and the PIP button on the remote.
