Please help I'm loosing my mind lol Can't Post
Hi all I'm new here. Ok I will try to explain the best I can. Ok tv is a olevia 265 with no picture. I turne it on and the olevia logo pops up nice and bright then gose away I Tested power at both power boards and all are good and I see no bad caps any where on any board. Now I used a flash light and yes I see a pic and yes I have sound I put a good used main board and still nothing. I turned it on in a dark room and there is no lcd backlight. I now pulled the left hand side inverter boards and the middle on on the back shows a little brown near a small black chip. I tested with s multimeter and on one setting I get nothing but on the other two boards I get a reading. Please help thanks Dan

Still wrong.

Start at the power supply. I only see one power board at Shop Jimmy.
Take your meter on DC volts and check for ALL voltages in stand by AND in run. (5VSB - 5V - 12V - 24V).

It has two power board looks like one feeds the right side and one feeds the left side and they are both the same. I switched them to see if there was any change but there was not. And all the volts coming out are good

CLICK the 'Shop Jimmy' link and then specify which board(s).

SJ only shows 4 Inverter boards. Each does have 6 HV transformers.

The power supply board would be the largest board with the heavy duty heat sinks.
