Re: Sanyo LCD TV DP26649

What is the number given on those two mosfets attached to the heatsink?
It looks like the DLA001A can be replaced by L6598D if it comes down to it.

A repair kit from Shopjimmy for no 12V /24V includes IC601, Q601, Q602, R619, R622 (both 0 ohm from Shopjimmy but both 10 ohms looking at the picture you posted. So I would check all these components.

mosfets = Q601 & Q602

I checked those R619 & R622 earlier, they measure 10Ω exactly, i dont know how to check mosFets w/ a Ω meter other than to look for dead shorts/opens
and it's outta my league on how to test a 16 pin IC
Jimmy's "shop" has always been a bit too steep for my bank account, I can get the whole board used for 28$...
I was just trying to repair this at component level, I'm not a board jockey fan, lol...to me, that's cheating...lolz

DB, you've been awesome here, put yourself in for a raise here at BadCaps...lmao
I truly do appreciate all the help here, wish i could buy ya a pint or 2


I still got 3 more TV's to look at (I hate calling these TV's anymore)
To me, they are Monitors with a TV tuner built in
...like "cellphones", I call 'em pocket computers w/ built-in phone,....
or "Gov't tracking devices"

Re: Sanyo LCD TV DP26649

was rooting around in my many salvage bins, I found a L6598D from another sanyo PS board, I may put it in there for S's & G's to see if anything changes there, I'll update here when I do... thanks again DB!!!

Re: Sanyo LCD TV DP26649

Turn the power off to the set. To test the mosfets put you meter into diode mode --!<!-- and check between the Drain and Source pins and then reverse the leads. One way should be around 0.4 and reversing the leads should be no reading OL. This checks the diode across the mosfet.
It wouldn't hurt to change the IC if you have one.

Will do bud, Today was a good day, I learned something
Much thanks again DB!!!

Re: Sanyo LCD TV DP26649

Did you check fusible resistor R632? It is under the big heatsink so you will have to test it on the bottom side of the board instead.

Re: Sanyo LCD TV DP26649

Hey DB, & anybody else who cares, I got this puppy fired up today, but don't ask me what component failed, lol, I replaced that 16pin IC601 w/the subbed one (L6598D) & the 2 mosfets Q601 & Q602 as well, Boom!, got my 12v & 24v & 384v PFC back!!!, went thru 3 fuses in the process, but don't tell anybody about that one..D'ohhh
Thanks again, I would have never gotten anywhere without the assistance here
