My t.v. dont stay on


Hi,

First do a hard reset. Merely unplug the power cord for 4 hours, then restart it. This will correct it if the cause is corrupted soft codes.

If not, the protection circuit has captured the power management and you must have it looked at by a service tech.

Let me know if there is more.

Have you acessed the power indicator error code by pressing in the menu and input buttons on the front of the set both in together and hold in for 5 seconds? The led will blink a series of blinks to indicate a 2 digit code which will repeat several times. Let me know what the blink seqience is.

When i press power the timer light flashes and the T.V. turns on and right back off.


If model number is WT-42311 do the self check the set has.

When power light comes on and then goes off, on front of set press both the Menu and Input (device) buttons at the same time and hold for at least 5 seconds and then release both buttons.

Power light will blink a two digit error code like: 2 blinks, 2 blinks, a pause and the repeat the code several times.

Let me know what the error code is and I will tell you what it means.

Most units give a error code "22" short protect circuit. If so check:

Q5A00
C557
and or the
convergence IC's (STK392-110) had failed and caused a diode (D522) to short
out.
If Q5A00 check bad there are other parts that have to be checked or
replaced.
