Question about Panasonic PT-45LC12 45" Rear Projection HDTV-Ready Television
When I power on the set, the I/O led blinks green for a minute or two, then blinks red for about 30 seconds, then goes solid red. Neither Temp. or LAMP LEDs illuminate. No picture appears on the TV. Fans come on as normal during this scenario, and clicking noise heard due to ballast trying to start lamp (also normal). I checked the bulb, looks fine. I read online that one fellow with the same problem simply replaced the thermal fuse to the ballast (99 cents!). Have you heard of this solution? Or do I have a bad ballast? I've read where people who replaced the ballast ($500!) started having lamps blow out very quickly afterwards. Have also heard Panasonic acknowledges ballast power fluctuations are causing extremely short lamp life instead of the 5000+ hrs as advertised! Any advice would be appreciated! Thanks!
It's a long shot, but it's what I am waiting on. Go to the Panasonic website and search for pt-45lc12. Find the order parts and supplies and look for thermal fuse (the ID should be similar to LSS###... etc.) Order 1 (or more, as this is a problem part) and then undo the entire set. on the backside of the teevee, you should see the fan, a vent, and under it a shiny metal box. unscrew it from the frame and disconnect all the wires to it (remember where they go back) and you'll see a small ceramic fuse. This is the problem with mine and I'm waiting for the part to come in so it should work. This is what a certified tech told me, so hopefully that's the extent of the problem. It takes a while, but hopefully it'll be back up and running shortly!!!

I took the rear bottom off of the set,lots of screws to take off.
On top of the bulb housing is a small yellowish thermal fuse.
I took mine completey out,jumped the black wire together,and bingo.set works perfectly.

This is battery
related. On top of your unit is a battery pack with three colored led
lights. You can tell what is going on by looking at these. This
information is in your manual or here it is.
GREEN LED: All systems are normal. A solid LED light indicates the batteries are fully charged. A flashing LED indicates the batteries are being charged. NOTE: Batteries do not have to be fully charged to operate the motor unit. YELLOW LED: The motor unit has lost power and is operating off of the BBU. A solid LED with beep, sounding approximately every 2 seconds, indicates the motor unit is activating the door and is operating off of the BBU. A flashing LED with beep, sounding every 30 seconds, indicates batteries are low. Once the power is restored the BBU will recharge. This is indicated by a flashing green LED. RED LED: An error has been detected and the BBU will automatically shut off. The BBU will attempt to restart by reconnecting to the batteries. If the error is still present it will shut itself off again. This process will repeat every 5 minutes or until the error has been resolved. This is used to prevent further draining of the batteries. If a red LED remains on when the power is restored, and is accompanied by a beep sounding every 30 seconds, please call for service.

Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen A2 slightly.
