On Panasonic if you are getting 3 blinks is usually a convergence failure. You can get parts with instructions on how to fix this yourself from www.TvRepairKits.com

Panasonic 51'' HDTV Model PT51HX42F - Turns off, light blinks 3 times, pauses, blinks 3 times again, etc.
the 3 blinks is caused by convergence failure indicating the Convergence ICs and resistors need replacement. You can get the convergence repair kit for your model at www.tvrepairworld.com the kit contains the ICs and resistors and also has the CD that shows how to do the repair.

I have a panasonic pt-47wx42 projection monitor. It will not turn on and the red light next to the power button blinks three times
The 3 blink error is caused by failed convergence ICs and the six 2.2 ohm resistors. Installing the convergence repair kit for your model should solve the issue. The kit is available from www.tvrepairworld.com the kit contains the 2 ICs with heat sink paste, the 6 resistors and the cd with instructions

The Crackling sound is most likely the Flyback transformer or HV splitter needing replacement. Does the power light blink? If so how many times?

I have a Panasonic HDTV Projection Monitor model PT-51HX42. It will not turn on and the red light next to the power button blinks three times
Three blinks is short protection in this model.

98% chance one of the protect resistors around the two STK-392-110 convergence chips is bad.

Good news here----total parts cost would be under 25 dollars on EBAY. I use a seller there.

I also have start to finish, step by step instructions for this repair in this set.

They tell you everything you will need and how to do the repair.

Let me know if you want help or the instructions--I can tell you how to look to see if the protect resistors are bad.

This is a very common problem and I have fixed hundreds of these sets with this problem.

If you need more help or want the instructions let me know, we will find a way to get them to you for free.

I have advice: DOES THE POWER LIGHT GO OFF AND THEN BLINK?

This set has a self check feature---the blinking power light should indicate what is wrong------a series of 3 blinks with a pause is short protection---common here.

A series of 5 Blinks means a short on the 140 volt line, more serious than 3 blinks but still fixable.

These sets all have a "SOS" SYSTEM---at least three protection circuits that will engage if something wrong and not allow the set to come on.

Let me know if a sequence of blinks---easy to miss if you do not know about it.

Bad color then no power on 51'' panasonic cinemavision
Check the power light for blink code--usually if this model shuts down the power light will blink in a sequence--3 blinks a pause and 3 blinks is short protection--usually means a convergence circuit problem.

Let me know what you find--I am here to help.

SD Tech you answered my panasonic tv with 3
OK, here is what I suggest you do----remove the light box from the set and unsolder all pins on both convergence chips----see if the set will turn on and light up---you can turn the set on with the remote--its receiver is at the top of the three black lens.
