I ALSO HAVE A 52 INCH RCA (2 YEARS OLD) I HAVE TRIED ALL OF THE TIPS THAT HAVE BEEN DISCUSSED. LUCKILY I PURCHASED THE EXTENDED WARRANTY ON THIS UNIT.. AFTER A MONTH OF OVER THE PHONE TROUBLE SHOOTING FROM WARRANTY REPAIR CENTER THIS INCLUDED REMOVING THE BATTERIES IN CASE THE REMOTE WAS BAD. THEY FINALLY CAME AFTER IT YESTERDAY. THE PICKUP BOYS SAID THAT THEY ARE HAVING A LOT OF TROUBLE WITH THESE UNITS DOING THIS SAME THING. THEY ALSO SAID THAT SOME WERE BEING REPLACED WITH NEW ONES. NOT SURE IF RCA OR WARRANTY IS REPLACING (MINE WAS PURCHASED FROM BESTBUY WITH BEST BUY WARRANTY). IF ANYONE HAS SPOKEN TO ANYONE ABOUT A REPLACEMENT PLEASE RESPOND. I THINK IF THERE ARE SOME UNITS BEING REPLACED WITH NEW ONES WE ARE MORE THAN LIKELY GETTING THE SAME DEFECTIVE UNITS (WHICH WILL MORE THAN LIKELY WORK UNTIL OUT OF WARRANTY). I WISH THEY WOULD JUST GIVE REFUNDS OR CERTIFICATES TOWARDS NEW DIFFERENT UNITS MAYBE IF THERE WERE ENOUGH COMPLAINTS THIS MIGHT BE CONSIDERED.

There is a fuse on the power supply board it says to only replace with ame fuse i understand that do i have to soder it out and in or is it more easily replaced.


hi there, if in case on your TV that the fuse is needed to solder out before it can be removed, yes you need to solder it out. But if it has this fuse terminals that you only need to tap it out better if thats the case. Some TV has this fuse terminal for easy access in replacing the fuse. if still needed to solder the fuse I suggest that do a little rewiring and put a fuse holder if available, if just solder the new fuse as is the same as the old one. hope this help, please rate and vote. good day

Cannot locate the fuse in the liteon power supply


The fuse is internal, and soldered to the circuit board. It can be replaced by soldering - an old-timers trick is to get a new fuse (with pig-tails) and just solder in parallel with the old - no removal needed.

How do I replace the FL231 fuse on the circuit board, removal and re-soldering I was told this will fix the convergence issue and that the convergence module is not bad.


Yes, but before powering the set back on you must fix the original issue that caused it to open. The high voltage transformer location LL008 will need to be un-soldered and all pins and pads cleaned. Then re solder the pins to the pads with solder. The original solder was lead free but it tended to crack after it heated up thus causing the intermittent connection and then opening the 400ma fuse to the convergence panel. The fuse is no longer available, but I have included a link to be able to purchase it on ebay. Make sure you ONLY use the size fuse needed as anything higher could be a fire hazard. Please take a moment to rate my answer. Thanks...

I am assuming that your unit cannot be powered up at this time. this is the result of a failed fuse or power supply board. remove the cover and check the in-line fuse(if equipped). if the fuse is OK, replace the entire power board. Now, if you unit isn't equipped with a fuse, you will need to check the solder on the power cord. make sure it is soldered on the power board correctly. if its not loose and, it is connected securely to the power board, replace the power board.

DS Lite will not power on


blowin F1 or F2 fuse or both inside your nds. can be fixed by runnung a bead of solder the blown fuse so it bridges the fuse (idealy you would replace fuse but its very tricky) first of all if you have a multi meter check the fuses before soldering them. anyway i advise not to use the homebrew card especially on your nds when you bridge the fuses as once the fuses have been bridged there is no saftey shut off to stop more sever damage. oh by the way just youtube F1 and F2 fuse location to find out where they are. oh and use a 15watt solder iron to be on safe side (less chance of overheating any components near fuses when soldering). its not that hard to do really (i did 2 of them with a gas solder iron due to me not having a 15watt iron) also replaced cracked screens. my next job to do is replace a L2 inductor on a friends nds (symptom for this fault is nds charges but will not power up, not even a blink of green light) for anyone who has this symptom its the L2 inductor thats broken away

Cant find the fuse on a black and decker 400 watt power inverter


I've had this inverter for about two years now, bought it for a cross country road trip to power my laptop and a couple of other things. I've pretty much liked it. Yes, the fan is a little noisey, yes, you have to use the provided battery clips for heavy loads. But it powers my Dell Inspiron 8500 laptop just fine (and its an old powerhog).

Recently a I let a friend use it with his inflatable mattress air pump during a camping trip.
What I didn't know is his pump has insane wattage, and it fried/bricked the inverter instantly.

Agh! I thought it was a goner, but took the time to look inside the unit. (Which is a solid and sturdy metal case, not plastic as another reviewer indicated). I was thrilled to discover there were some internal fuses. And while the fuses are soldered to the circuit board, if you've done any soldering at all they really are a snap to replace.

If you remove the four screws that hold the end cover plate on the side with the fan. You can remove the end plate and have just about a half inch or so of clearance. The entire lower circuit board will then slide out with firm pressure about an inch and a half (don't try and go any further, components on the other side prevent it).

On the right side (positive/red terminal side), you will see two 25 amp mini-fuses that are directly soldered to the circuit board. If these are blown (you can see through the semi-transparent sides if they still connect), that is most likely your problem. They are easily available from most auto and big department stores (Walmart, Target, etc) in their automotive sections.

I used a 40 watt soldering iron (30 watt should work fine), and applied it to the bottom of the circuit board where the fuse legs poke out the bottom. Using a pair of pliers, I applied a firm steady pressure to the fuse, pulling up, while applying the soldering iron to each of the legs (alternately) of the fuse. The solder melted, and I was able to work the fuse out in a few seconds. I did this for both fuses.

The replacement fuses cost all of $2. I dipped the new fuse legs in flux, then put them in the place of the old fuses. Again I heated the circuit board solder from below, and pushed the new fuse in place. Repeat with the second fuse until it is in place. Flip the board over and add some more new solder until it is firmly in place. Put it back together, and you are back in business! And for a whole lot less than a new inverter.

I've got pics of this process if anyone would like them. Good luck, and happy inverting.

My FSP145-50N power supply won't come on, I think it is the fuse, but wher is the fuse located anyway?


Hi, remove the power supply from the case, [easy job] examine it and yuo will see about 4 or 5 screws holding the cover together.

Seperate the 2 parts of the cover and study the printed circut board. The fuse will be a glass tube type fitted to this board. Some PSU's have the fuse soldered in place and you may need to solder a new one in, otherwise it will just unplug and replace.

MAKE SURE YOU REPLACE THIS FUSE WITH THE SAME VALUE FUSE, available from computer repair or electronics store. regards mistyman
