Question about Olevia LT42HVi 42 in. LCD Television
The TV would shut off while watching. Now it won't turn on. The blue light on the power button goes on and off when pushed, however no email@example.com
Olevia has problems with the power supplies. Best solution is to remove the back of the TV. On the 542 it is about twenty number 1 phillips head screws. locate the power supply connectors check the board for the voltages, clearly marked on the PCB. Continue to check the voltages by powering on the Television. all voltages should be within its described range. If a voltage is low or nonexistent, the power supply is bad, usually a bad capacitor.
There are three series of caps, on the low voltage side it is 16 volt, next 24 volt and finally 36 volt (these are just max ratings.
which ever power that was found low the cap would be near that voltage output connector.
next step is to remove the board and replace the capacitor, using a soldering iron and making sure to solder with no slop.
with the board on an insulated (nonconductive surface connect the board to the televion. Check voltages and if no other voltage issues reassemble.
