Blue power indicator light is on. No picture and a Constant clicking noise coming from back of tv. I look inside the back of TV and see a light that is trying to come on but after the click it just go's back out.

Taran 2005 , did you get my answer.

Thanks for your response!!

This is almost certain to be a hardware failure. There could be a couple of reasons which are quite common on these models.One is the power supply board and the other is Z sustain board.

You will need to remove the back cover to
troubleshoot the plasma you will also need a digital multimeter. I will
bet you have a defective Z sustain but you have to be sure you dont want
to through your money away by shotguning the set with boards.

First
look for missing voltages at power on each connector (not just Vs and
Ve look at all the voltages they are marked on label near the top of the
panel) should be labled with the proper voltage. If you have one start
with the missing voltage and troubleshoot back, it is hard to say what
the ultimate failed components would be but you should be able to track
it to one board.

Rule 1 is troubleshooting is "start with
your sense"

1. Look
2. Smell
3 Listen
4.
Touch (not recommend)

These are the best giveway, if it looks
damaged it is if it smells burn it is, if it sounds wrong it is

1.
Look - examine each component on the board look for something burnt,
swollen or distorted, and look at the fuses.

2. Smell - Smell
around the set see if you can smell a burning smell on any of the boards
.

3. Listen- Listen for a buzz or an arc out of one of the board,
it may be normal but unlikely if you have a defect.

4. Touch-
Important because if the parts are getting hot then they are running,
but if they stay cold they are not.

As for touch not the
best idea on a power supply there is a high risk of shock, as some of
the heat sink may not share ground and possible have a potential to
earth ground between 5-500 volts.

You will need a DMM to
check the diodes and the transistor non should read a short, if any do
you will need to remove it and check it out of circuit if the component
is not shorted but the short is still in circuit use the schematic to
follow the leads to where else the short could be coming from and
repeat.


Next remove the connector connecting to Y sustain
and the Z sustain to the power supply and attempt to power the set on
if the set powers with the connectors disconnected you have more than
likely identified the issue as a failed sustain board now to go further.

Now reconnect the power connect to the y
sustain and see if the set powers remember you will not get a picture
but the lights on the front should stay light.If the y
main connected causes the set to act up remove the buffer boards and
attempt again, if the y still causes the issue you have a failed y
board. If disconnecting the buffer resolved the issue you have failed
buffers and possible a failed panel, try replacing the buffers.If
the Y board connected the set still light normal disconnect the board
and connect the z sustain and test the same as the y, if that causes the
issue replace the z.



In my personal experience I would at
least have the set professional examined most good shops charge less
then $50 mine only charges $25 so it would be worth at least getting an
estimate.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
