TX-R3079WHX/XAA Blown fuse

Hello, My TX-R3079WHX/XAA was working fine and the only fuse I could find on the board had blown, It looks like the old car fuses. I source a replacement fuse; and the set worked for two weeks and blew it again. The set is plugged into a surge protector. I?m not scared to learn and fairly handy with electronic and soldiering, what should I look for that would cause this intermittent surge or failure? The set works fine unless the fuse is blown then nothing, its elevated out in the open and under a roof so I don?t believe water and excessive heat are an issue. Thanks!

    2005 Tx-R3079WH. Turn it on and runs for 20 minutes then audio goes out, video goes out and set powers down. Trying to ascertrain if it is worth the expense to fix. Plus hard to find anyone to work on the old tube style tv.

Snakehead, Thanks for the suggestions; I'll check out the kit you mentioned. Since the TV?s death and the lack of warranty its become a hanger for my wife?s cloths. I will be happy to get it going again! - JT

Greetings from belize make good checks in your power supply replace your voltage regulator it has an short which is activated after accumulating heat.change the horizontal transistor.and the bias diode the feeds to the B+ to the flyback.if that does not solve the problem replace the flyback.your problem is intermittent so you cannot check voltage just replace components matter of fact replace all the components in the power supply you can buy a kit from in miami florida.good luck.

My monitor 940n samsung syncmaster gone in black...

I have just had this same problem. The problem mostlikely is a blown fuse on the inverter board. Mine was blown on the board and also a Capacitor (470nF/25V) was bad beside the Fuse.

I replaced both and monitor is working now again. After install the picture was a little grainy with little artifacts. In another post i found that the Power Supply board needs to be cleaned for unwanted residue. After that picture was fine again.

BEWARE that you need a soldering iron and a steady hand to replace these parts. If you are unfamiliar with soldering at all have an expert take a look at this. The Power boards uses 220v so DO NOT connect it to the Power when opened.
