General, these failures are produced by power sources, because of which refer to a wider area, so that can be divided them
two conditions to explain: no B1 115 V and existing B1 115V.
(1) No B1 (115 V) voltage (voltage of network 220 V ac)

These failures may be caused by abnormal operation of horizontal scan, to confirm which can observe the filament of

drive stage. Search upward to TMPA8821 with method of checking DC voltage and waveform according to sequence:

Falla Reportada / Motivo :
METODO PARA ENTRAR AL MODO DE SERVICIO
DEL TELEVISOR.
Solución aplicada :
La “D” en el Manual de Servicios significa Modo “D”. Los modos de fábrica son el Modo “S” y el
Modo “D”. En el modo “S” sólo se pueden ajustar algunos parámetros; mientras que en el modo
“D” se pueden ajustar todos los parámetros. Para los Chasis TMPA8823 (TV´s de 14” hasta
21”) y TMPA8859 (TV´s de 25” hasta 34”), se puede acceder al modo “S” utilizando el control
remoto del usuario siguiendo los siguientes pasos:
Presione el botón VOL - en el panel de la TV hasta 0 (no suelte el botón VOL -), luego presione
el botón DISPLAY en el control remoto para entrar al modo S.
Si se quiere acceder al modo “D”, para el Chasis TMPA8823 (TV´s de 14” hasta 21”), siga los
siguientes pasos utilizando el control remoto:
Primero siga los pasos para entrar al modo “S”.
Presione el botón DISPLAY en el Control Remoto.
Presione el botón VOL - en el panel de la TV hasta 0 (no suelte el botón VOL -), luego presione
el botón DISPLAY en el control remoto para entrar al modo D.
