    Philips PSU problem

    Hey Madcappers, Greg here, having an issue with my TV and told this was the place to come so here goes...

    Item: Philips 42"LCD TV- 3 years old
    Model: 42PFL5405H/05
    PSU: LG
    Power supply: 230v {Ireland}

    Problem:
    Tv was on standby, pressed the power button on the remote- loud bang, some smoke and a few sparks. Then nothing- no life in the tv. The 3a fuse in the plug also blew. My PS4, SKY box and router that were plugged into the same adapter block were all unaffected.

    I removed the back cover and the PSU {im an electrician so safety measures were always in play} and discovered that a disc capacitor had exploded. Unfortunately due to the damage sustained the specs are somewhat illegible. The cap has been removed and cleaned a bit so im pretty sure it reads 1kv and the 'k' value begins with 10, other than that ive no idea what the specs are.

    So its time for the electrician to sit down and stay quiet and let the electronic gurus tell me what's what....

    Some Questions:
    Why did this cap blow, is there a history of them being faulty or is it a bigger problem?
    Can the cap simply be replaced? If so will the TV be safe i.e. fire hazard?
    Can anyone correctly identify the cap and specs so i can order it?

    I've attached some pics so hopefully they help, cap location on the board is c502, any help would be great

    Cheers guys

    Greg
