    Trouble fixing a Phillips LCD TV's powersupply

    I was given a Phillips LCD 32" Television that had been hit with a lightning strike power surge and no longer works (model # 32PFL3506/F7). I opened it up and found a blown fuse that I replaced, but it kept blowing when it was plugged in. I did some research on the internet and did some multi-meter tests and found that the diodes and the mosfet were dead so I ordered new ones and replaced them (shown in the pictures). I put in a new fuse and re-plugged it in and the fuse burned out instantly and the diodes I replaced were fried. At this point I don't know what to do and would appreciate any help you all can provide. Here is a link to a site selling the exact board I am working on, unfortunately no site is selling it for a reasonable price and the ones that are are sold out (http://www.shopjimmy.com/philips-a17...-mpw-board.htm).

      Was it plugged into a surge protector when the lightning strike happened? And I really don't trust that HEC cap at all, those things are of the worst quality. You should post some close up pictures of the other board too

          Im not sure of the details but I do not believe it was plugged into a surge protector. I found a replacement board on ebay for a price that im willing to pay (link below), and I also will link to a site showing the inverter board (the other board you requested) as well as some pictures of the inverter board on my tv set. I want to purchase the one off of ebay but only if it will solve the problem, i.e. is it possible the inverter board was messed up too? im not really sure how extensive the damage would be or if it was just stopped at the blown fuse. again any help or insight into any of this is greatly appreciated thanks for your time.

              Argon SA1 audio amplifier power-supply - fuse blown after fixing the short?
              by Babbar
              I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.

              Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in....

              A funny fuse story – Lumix LX100 II
              by corrize
              Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
              I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
              The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
              There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
              And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping...

              Samsung UE46ES8000 Blown fuse but no other signs of short
              by jesterace
              Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the...

              Help replacing fuse on my Mimaki CJV300-160 vinyl printer
              by jshhh
              Hi guys,

              I'm inexperienced with electronics repairs, I've done a little bit of soldering caps and whatnot, but i have a blown fuse on this mimaki printer I got which I have bought a replacement for.

              How do I remove this type of fuse (see picture)...it kinda looks like it would pull out of that bracket but it didn't come at first pull and I didn't want to brute force it incase it's soldered on there like most of the rest of the components.

              Anybody know how to remove this type of fuse?

              (The fuse is toward the bottom of the image labeled F2)...

              Trouble fixing Panasonic su-htb500 sound bar
              by chuds
              I am repairing Panasonic su-htb500 recently, the main power supply is not powered, the standby power supply is 5.84V, I replaced the capacitor C5726 on the main board of the power supply, and now I find that the output voltage of ic700 is only 0.4v, and the main power supply still can't work, can anyone provide a repair In addition, I also found a problem. The pins of IC700 are different from the common ones, and the information cannot be found (the part number is C0CBABC00117). Does anyone know what type of IC to use instead, thank you!
