My tv rca l26hd31 has no sound and no picture
First, look at the screen in darkened room to see if you can see
any slight glow from the screen, if it does, then the problem can be the
T-CON (not getting the 12vdc) or the main logic board not feeding the
signals to the T-CON board.
if not, next place to check will be the power supply module, make
sure it has 24vdc which is required by the backlight inverter to work,
the reason for not having 24vdc can be from bad DC filter caps
(leaking/bulging top, high ESR) or short circuits in the inverter board
which will cause the 24vdc supply to go into shutdown mode, so you may
have to disconnect the power cable that feed the inverter board to see
if the 24vdc will work without the inverter board hookup, you will need
to apply about 3~4 amp of load to the 24vdc to make sure it can handle
that. There are fuses on the backlight inverter boards also. So there is
some troubleshooting you will have to do to find out the causes of the
problem you are having.
SOURCE: The TV would not stayed turned on. Then the
I would start with finding online and replacing the power board.
SOURCE: Cannot connect my pc via hdmi to an RCA L26HD31.
