Shut off all lights in the room, use a torchlight and shine it directly into the LCD screen. Can you see any images? By the way, its not a simple fuse replacement. If the main fuse was blown then there would no power at all. If the inverter fuse blown then there could be some problems in the inverter section (possible short and/or component failure). hmm.gif

Check the fuse in the main 3-pin plug if exist (usually very rarely spoil as this fuse is rated at 13A). Before this happened, were there other signs of monitor problems such as flickering, banding, reddish background (where its supposed to be white) and intermittent power issues (cannot switch on sometimes)? Besides the internal fuse, failures in other components such as power thermistor, capacitors, diodes and main switching MOSFET can lead to no power problems. The only way you can determine that is to open/disassemble the monitor and check the IP board (with some tools, such as a multimeter). hmm.gif
B4 the monitor blackout, i was watching movie connected from laptop. No problem all this years.. screen was like it was first bought xcept a little dimmer.. i tout at first the backlight was blown but when i c the blue blinking light also gone, i knew it has to be sumtin like fuse blown out as it got like no power at all. Could it be the cable connector that connect the lcd monitor to d wall socket? I dub any xtra cable to test unfortunately..dem

First time fix it, no clue what the cost, at least save a Rm800 lcd. 

Next time send it to you.  thumbup.gif  rclxms.gif

Even format and reinstalling OS, shops also charge Rm50 nowadays...  doh.gif

PS: At least in my company area, providing troubleshooting job for company, generally price range is Rm50-100 (labour cost), from ordinary machinery, forklift to electrical part/components.

Haha, u remind me of sumtin funny but kinda sad in my case. Back in 1998, when i was form 1, my mum bought me a playstation as a reward cos im willing to study in d boarding school in limbang sarawak, that tym my dad is working brunei. The moment i came back home on d weekend,very excited wana play d playstation, it wouldnt turn on, very devasted n frustrated,my immediately bring the ps to nearby shop to get fix. Xtually the fuse blown out n they charged it 30 brunei dollar bout almost 100 rm our money. Few years later when i was in form 5, similar thing happen, try to fix it mycef, n go to nearby electrical shop to lookfor a fuse replacement for my ps.. n know wat tgat fuse cost a mere 2-3 ringgit a piece.. demmit kene con lastime hehe
