Hi Members-my 1st post about repairing newer stuff. i find it difficult to find schematics/service info for the newer flatsceens(i ussaly fixed the board instead of replaceing it in the past). in most cases,if i can get the data,i can troubleshoot and repair boards.
is there a site or 2 that has data for flatscreens like bama's vintage data?
i would like to find the schematic of the power board in this set(used in a few from what i have googled).board # ccp-3400st. even if i had the proper output voltages for the backlite,that would help.backlite outputs through connectors cp7002 and cp7003.

this set was dropping brightness on 1 side after warming up. i confermed it was the power supply by switching the 2 cables going to these connectors and the drop in brightness switched sides.
i went to grab my cold spray to trouble shoot the thermal problem but then the backlite quit.
backlite comes on for a sec when powering up,then goes dark-rest of the set works well.

i did change the 1 cap that was rated at higher voltage(47uf @250v)but no change.

any idea where to get this info or even just a pinout that includes expected voltages?
thanks for reading this.
