WS-55511 This TV will not power on, power light comes on for a few seconds then back off again, any suggestions? Lou

How did you get at the part/s? remove chassis or just the center board? I suspect something happened when you repaired the set.

Does the self check which even if set does not come on, power light comes on for a few seconds and goes off, do the self check (let me know if you need to know how) and see what blink code the power light gives.

After you turn on and green power light comes on and then goes out:

Press and hold both the menu and input buttons on the front of the set for at least 5 seconds and release both buttons.

Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it 4 more times.

Let me know what error code and I will tell you what it means. If this information told you something you did not know, rate this solution as very helpful as I do this here for free.

Do this: When you turn it on and the green power light comes on and goes off:

On the front of the set press and hold BOTH the Menu and Input buttons at the same time for at least 5 seconds and then release both.

This model has a self check: The green power light will then blink a two digit error code: most common is 2 blinks, 2 blinks and a pause and repeat the error code at least 5 times.

Let me know what you find and I will tell you what it means.

I hope you get 2,2 as it is the most easy to resolve.

A question to which you have the answer?

Does the green power light come on for a few seconds and then go off?

Check fuses if open then IC is bad

Hi if its a Lcd or Dlp rptv most likely its time to replace the lamp if tv is between 2-4 yrs.If you hear clicking it could be the ballast which is the board that powers the lamp.Make sure fans are running ok ,dust them out if they are dirty.God bless you!

Listen: you need to wait for the set to first shut off! then push on the TV(not the remote) Input and Menu both at the same time for 5 seconds and then release---the power light will then blink---this model has this feature--

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:


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

PRESS AND HOLD “device” 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 protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


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


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

Replace both of your convergence ICs they are STKs big black ICs will have part number on them.

I sent it out for repair. $700 bucks total, but now the color is bad and the HD isn't set properly. They'll be coming back out this week sometime to fix both.
