Repetative clicking sound when tv is plugged in with no picture or sound like its unable 2 switch on


TV is very common for having a power failure issue. The problem resides in the Y-Sustain board in most cases. The HDTV Television also have the same issue as they all use the same PDP Panel (plasma panel).

Loud popping and loss of power is common on plasma TVs and is usually either the Y sustain or Z sustain boards or buffers; in these instances the damaged part will be quite evident.

If this is an LCD you might have degraded insulation on one of the pink/blue back light power leads causing high voltage to 'arc' to the chassis.

The loud bang and smell is actually to your advantage as in these circumstances the damaged part is usually evident. It'll just be a matter of popping the back off and sleuthing around

That's the sound of your power supply going bad. You will have to have it repaired by a professional television technician.


Before making any purchases, please check the part and make sure it is what your TV needs. I am simply making recommendations and trying to point you to the right direction.

Good luck.

MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "input" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

Tv randomly shuts off


next time it shuts down and power light goes out--do the self check.

On front of set press and hold BOTH MENU AND INPUT BUTTONS FOR AT LEAST FIVE SECONDS AND RELEASE BOTH BUTTONS.

Power light (if an error is detected) will blink a two digit code.

Most common is 2 blinks, pause and 2 blinks---set if there is a error code will repeat it at least 5 times.

If you detect a error code, let me know and I will tell you what it means.

50 inch Plasma problem


Most likely a capacitor in the power supply went out. otherwise it may be a bad relay if there happens to be one.
Most reason for a tv not turning on at all is bad power supply

Check your cables and TV input settings.  Can you get to the on screen menu?  Does anything appear on the screen when the tv is on?

My LG Plasma is only 20 months old - its a 60 inch panel with HD tuner - the tv keeps turning itself off after about 2 minutes - why does it keep doing this?


Your tv needs a software upgrade, check with the tv manf and see if they have one available, usually they have it online for free

Have lg du-42py10x plasma powers up but no picture no sound dark screen with white dots


if you have checked the activity of the outlet and the status of the TV (turned on or off) you may want to get it check through an LG authorized repair center, the issue could be the switchboard that channels the video and audio.
