Your TV is showing symptoms of power supply failure. It needs to be repaired or replaced. The remote has nothing to do with the power supply problem

My panasonic TH42PX60U won't power up. No red light flashing. Completely dead. I tried unpluging and using different power outlets. Still nothing. Any help?


1. Check all cable and input connections are secure & all are tightly connected.
2.Check power cords and also power outlet , if possible try to unplug and reconnect . A replacement of power cable or use another power outlet is another good option.
3. If you are sure that power is reaching your TV(check it out with a test lamp that both neutral & ground or earthing is functioning, i.e. the test lamp glows) then probably the power board needs replacement.

I have a panasonic projection TV, PT-60C13 that will not turn on. Upon pressing the power on button, the button flashes green many times, then flashes red five time then one orange flash. This red/orange...


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.

After changing the bulb image will not come on and solid orange light appears


Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

When turning on my panasonic cinemavision tv, it makes a click sound then the power button light flashes red three times, no picture comes on the screen, any ideas what should be done?


Most likely a power supply failure although the flashing of the LED a fixed number of times may point to something else such as a lamp failure. If you can find a forum for this series, you may find a Panasonic tech who can give you a better read on this.
