Panasonic pt 52lcx66 won't turn on

One day my tv just started to dim out I could see an image and sound but it was really dark, later the next day the tv woudn't turn on, just blinked from green to amber on the power light. I replaced new bulb but didn't fix. Any idea which part might be broken, light engine? transformer?

    When we switch the power on, upon 2-3 seconds the Green light (for Power) turns on and within next 2 -5 seconds, turns Orange and blinks thrice and goes silent. After couple of minutes the the orange light blinks thrice and goes silent. We thought the problem couldbe with power trip, verified everything was fine. Left the TV on for halfan hour (it continued with the orange light) blinking thrice.

Sounds like the light engine. Is this a DLP or LCD rear projection? Did you see any patches of color any time before the problem with the really dark screen. Please rate my answer and let me know what other questions, Tech Malick

Does the panasonic PT-52LCX66 have a reset switch or anything for after replacing the lamp assembly?


The reset directions should be included with the replacement lamp. If the sheet is missing, you can get a copy here: http://images.panasonic.com/static/Content/productsupport/TYLA1001.pdf .

Plug in the TV and turn it on. Press and hold the Vol - button on the front of the TV then press and hold the zero ( 0 ) button on the remote for more than 5 seconds. You will see a Lamp Reset message on the TV when you are finished.

I hope this helps.

My panasonic pt-52lcx66 it wont turn on what can i do myself


yes they do; They have glass fuses than have the thin wire running across on the inside. If the wire isn't running all the way across the fuse or is broken, then it is junk. If fuses is good, then power supply may be faulty which is quite common these days with newer electronics
