The problem sounds like hum bars that is the term when ac power is leaking on to your set from the power supply in simple terms .
televisions have a switch mode power supply and the front stage of this is the AC filter one or two large capacitors that block the ac from your set these are set across the + and --_ terminals of the Bridge rectifier the device that converts the AC into DC .. this is not a fault that should be re-ocuring so often especialy with this age of set , unfortunate that this was only repaired so recent but a new board may not realy be needed here just a few components I suggest you get a free estimate done on your set , warranty work and insurance work is always loaded , but private work has to be competative give it a try you may be pleasently surprised
