Hey all...
Could anyone tell me what part this is on the power board?
... it kinda looks like a cap.. but it is not. tuning coil or something?
... I added an arrow pointing to it.
It appears the legs on the bottom have been kinda pushed out.
It's the only thing that even looks bad to me.
TV: Vizio : E320-B2
Power board model: AMP32-VW
Symptoms: Vizio logo barely shows up..flickers a bit.. then shuts off.
A bad power board. But I think it may be this specific part that is bad.
THE PART...

Insignia - NS42E760A12 - led replacement?
Insignia - NS42E760A12 - led replacement? ie: the lights.
- Could someone point me to a good place to get new led lights for this tv?
.. for they just keep going out on me... crappy Insignia! don't get those!
...the led lights.. not the inverter.
But more of the better question is...
*** I assume just any led lights from any led tv will be good to solder in?
...for i have a couple of spares. yeh i'ma try that anyways huhuh....
Stupid insignia! with ur lights going out on me.. jeez.... stupid lights!
So yeah.. if the 2 broke...Last edited by lllllllBOB; 07-18-2017, 12:09 AM. -
Re: Sanyo Dp42740. any hope of fixing this?
Thanks for the reply man.
[b]Update: :-( [/b] nevermind on the power board. or pfft it could be that as well.
While the screen itself is still not Broken as far as I can see. and after re-checking again....
[b]--->[/b] There's a nick in one of the flex cables coming from the screen. Ouch. :-/ dang....
... the small nick appears to have severed the very outer connection on the cable.
[b]--->[/b] Would that too give a no power light and no standby light? i'm guessing it... -

[b]Sanyo DP42740. [/b]
[b]* Problem:[/b]
When plugging it in.. it makes a few clicks.. and a short whining sound.
- No power light at all. tv will do nothing else.
[b]* Reason:[/b]
Was knocked off of stand onto the floor. was caught half way. but still hit the floor.
- and while falling.. the cord was yanked unplugged from the back of the tv while on.
- Nothing is physically broken. screen looks good. boards looks good. no cracks.
(My uncle gave this tv to me. his son knocked it over. not me. lol)

Re: K7T266 Pro2 help needed. "Died"
* I crudly tested the caps using visual analyser pc osciloscope with built in signal generator. along with a couple of resistors....
To see if would work, I first tested known good caps.. the squarewaves would demenish when testing good 1000uf and up caps...
When testing a known clearly "buldged/bad" cap of the same uf, the squarewaves would appear as sinewaves...and or obviously appear very different... if you wanna know the wiring connections sch, let me know.
It seems like it works fine to me......Leave a comment:

Re: K7T266 Pro2 help needed. "Died"
Welp All, It's Not the Ram. Installed new ram stick, and no go...same thing.
but that's ok, I can use that same ram in the pc im on now.
*Is there any way possible, to test a capacitor without an esr meter?
Besides just checking for reverse polarity or a short...
and I mean, anything that would give the slightest clue. anything at all?
*What about checking the caps with ohms readings.. does a good or bad cap read any certain amount of ohms? Like if it reads low ohms.. it most likely...Leave a comment:

Re: K7T266 Pro2 help needed. "Died"
Thanks for the cap info... It has plenty of room for any 1500uf size.
Yeah, I wasn't sure about the memtest either...i figured it would fail even if the ram is good or bad. I just wanted to see if it would actually run the memtest. and it did. booted it right off the cd... and ran good. besides that it was failing all the ram test. Kinda sounds like bad ram after that. but i guess it could also be a bad cap not supplying enough power for the ram slots.
A bad cap near the ram, bad ram, or both? huh huh..

Re: K7T266 Pro2 help needed. "Died"
Hey shadow or anyone...
I suppose memtest would fail the ram test if there's something else wrong with the board itself right? Else the ram might be bad, Cause I just tried memtest boot cd and all the test was failing, as I figured it would do anyway. So I just exited outta that cause it does a lot of #test..
*and If the processor was bad, wouldn't the memtest not even run at all?
and yes, when I clear cmos, I can do anything in the bios or slelect any boot device without any problems.

Re: K7T266 Pro2 help needed. "Died"
Could someone tell me if I can substitute these cap values?
[1000uf 6.3] sub to: (1000uf 10V) - I know this one is ok.
[1500uf 6.3V] sub to: (2200uf 16V) - ? Is that to much volts/UF?
[1500uf 16v] sub to: (2200uf 16v) - ? This probably should work here right.
Thanks for the help all...
If these values will work, then I don't have to buy any caps. lol
and I'm real happy to learn that in order to even test a cap I need a $100+ esr meter. great..... might as well buy...Leave a comment:

Re: K7T266 Pro2 help needed. "Died"
Well that makes me feel so much better...
Why do you say it's not the caps?
I just cleared the cmos again, and it got to the screen that ask to load windows in SafeMode or Normal and ect... That tells me it read the drive and also knew that windows tried to boot a previous time and failed.
I chose normal and it acted like it was gonna load, then it FROZE UP.
* That surely sounds like bad caps to me. What about anyone else.
and I read here that Teapo caps are known to...Leave a comment:

Re: K7T266 Pro2 help needed. "Died"
Hey shadow..
Do you known if 10V caps would work instead of 6.3v? probably?
or would that draw to much current and make other things go out?
I called the only place in my town, and they want two dollars a piece for them! Isn't that a tad bit high for some 1000uf caps 6.3v? and the 10mm 1500uf was 50cents cheaper than the 8mm 1000uf? what tha?
Thatta be ok if I ony needed two....lol
I Need (10) 1000UF 6.3V and (3) 1500UF 6.3v
I think I'll just have to dig in...Leave a comment:

Re: K7T266 Pro2 help needed. "Died"
Hummm... here's something.
If I clear the cmos, it boots to the bios setup.
When this pc was working... right before it shows the xp loading bar... I would see a black screen with a wide loading bar go across the bottom of the screen,then it would show xp loading. When I cleared the cmos, and set bios defaults/and or selected the boot drive, I saw this wide loading bar. along with the drivelight lighting up, but then it hung on that wide loading bar and the drive light went out before it got to booting...Leave a comment:

Re: K7T266 Pro2 help needed. "Died"
dang.. didn't have the right spare ram stick.. had old sdram instead of ddr.
If I take out the ddr ram stick...
I get 3 repeating beeps. Telling me there's no ram I suppose.
When the ram stick is in, I get no beeps. nothing.
So does that mean that the ram stick is good then?
I think I remember upping the ddr voltage by 1 in the bios at one point for better performance. Maybe doing that eventually fried the ram?
Buying a stick of ram sounds better than replacing 13 caps that look...Leave a comment:

Re: K7T266 Pro2 help needed. "Died"
So it possibly could be the ram? I may have another stick around here somewhere to try. Wish I'd tried that before I unhooked everything eh...
Yeah, the pc has a speaker connected.. I heard No Beeps. nothing but fan sounds.
Here is my cap list:
Teapo: (10 of 'em) 1000uf 6.3v
G-Luxon (3) 1500uf 6.3v
Rubycon (8) 2200uf 6.3v
KZG (3) 1500uf 16v
I think it would be cheaper just to go buy the same board on ebay. lol

Re: K7T266 Pro2 help needed. "Died"
The pic from The link above I mentioned looks like the same board just minus the usb2.0 chip. and minus the obvious bad caps and some brands that they have on theirs.
Well, I read some more hear, and people say the kzg and Rubycon caps are good. So looks like I'll have to replace the G-Luxon and Teapo caps?
Man.. I hate to replace the caps when they don't look bad at all .
But you say you've seen bad caps that wasn't showing any signs right?

Ok, Here are the brands that I see on the board.

I done a search here, and a few k7t266 came up..

It does read K7T266 Pro 2 Ver2.0 on their picture and on my board.
