Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Hey yes I searched google to cant find any.
I searched for the whole powerboard at shopjimmy but the current board is out of stock - that would be a easy solution - though the prices shifts alot.
And ofcorse its a little stupid if its only one part that is burned, but yes depends if it to difficult to find or it maybe is other issues like the leds etc can see others on the forum having problems with that

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Hey thanx. Hmm unless my cheap multimeter is to "off" its reads constant 1 on all legs of all these 3 components. I have the 200ohm on the meter - just took a picture of it - a bit unsharp i know my macro photolens is a bit hard to control
or it can be my 35 years old eyes - no comments
Alle 3 had the middle leg with no connection - se the photo mosfet example
The top [B]QM854[/B] dosent look burned actually
Its named
D4184...Last edited by adaugaard; 08-13-2014, 02:46 AM.Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Here is a better and bigger picture of the back.
I had to take 2 pictures and set then togeather in photoshop... thats why it loks a little "funny" but it should still work I think.
Not all are numberet but i did with the ones i thing are major components. Else just say if there is other numbers fron the front board picture you need, then I will put them there. I keept the same numbers making the reference more easy i think.
There are 2 pictures...Last edited by adaugaard; 08-12-2014, 07:08 AM.Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Hey just messured nr 21 - it dosent give any response on VDC200.
The meter switches around 0.00 and 0.01. Power is on and fuze is still ok.
Could this be the "bad" component we are searching fore ?
I will make a better picture of the back with numbers....Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Ahh damit i use a mac so not much into windows anymore.
But i do recall there is something called program compability when right clicking the program icon. making older program versions run under win7 etc.
Why is the 5a fuse bad idea - there was a 3a in the tv from start. is it because its to big and will not 'release' before damage is done to the components...Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Gtt a 5a/250v fuze - is that ok to use. There was original 3a/250v in the tv, but the store was out of that fuze type.
I know some of my questions is very basic hehe, its a new world in my head... but what a exiting world
Any thoughts what to messure after we did test the last part where there was no volts at all...Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Hey yes sorry ment 0,35 ma. BUt as long as its not blown I asume I can keep on messuring things - if it was blown would there still be 320v on the capasitators.. the 16 and 17 on my front pictures of the board ?
But I will get a bigger ofcorse - its stupid to messure anything if the fuze can mess up the readings ofcorse.
Thanx again - and sorry for the delay - was on a trip to germany with the family...Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
yes everything is connected - i just loose. the screws and turned the board around.
be aware that I switched the fuse to a new one. the new i got is
called 350mv250v where the old that i 'killed' was called 3,15a250v
. much bigger but aslong as there is power through i asume that fuse is not a problem right?...Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Hello again. I messured with power on and ground taken from the copper dot.
Still shows 0 on alle pins.
Of corse the boards is not psycal conntected to the iron on the tv - as you can se on the picture - but I asume it still gets ground right ? else i have to wire from the cobber to the ground metal frame on the tv.
I asume that means it dosent send anything to the next board on the left side of the tv. So the problem is still indicated to be...Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Ok super news about the bridge
It says 1 when messuring fuze. - I will get a fuze somewhere around the city.
When I have that I can start messuring the things again as you describes longer up this thread I think right ?
Again thanx for super helping...Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
test the fuse solderd to the board no need to lift any legs at this stage,meter on resistance 200 ohm,power OFF reading: 0 - no response - asume this means it killed the fuse right ?
bridge rectifier (18) number pins left to right 1234
meter set to diode test power OFF
black probe to 1, red to 2 reading? 0
reverse probes 1 to 2 reading? 483
pins 2 and 3 should have no reading either way: correct its...Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Hey Multimeter.
I attached a new picture with letters on each "leg" on each part now also... since it requires that i thing when explaining...
I made a big error at the start up (and one on the end of this comment).
1.Startup error
Pretty simple i know but the fuze leg was cut off when messuring the resistance... that way its logic there was no action up to nr 18. I put the leg...Leave a comment:

Re: Samsung tv dosent turn on (no signal/standby light out) after lightning hit the h
Hey Multimeter.. sure can.. front and backside are attached here.
The frontside have full sets of numbers. Some of the pieces with 4 legs i have given a "a,b,c,d" maybe making it more easy to explain what to meassure on those units.
thanx...Leave a comment:
