i hate working on crts even after a week or longer you can sometimes get a nasty shock search on youtube regarding discharging the crt voltage correctly.

Edit this may help

Re: samsung CRT security monitor wont power on model ssc-12

im having a real hard time finding any of the components you mentioned....this is a single sided board correct?

Re: samsung CRT security monitor wont power on model ssc-12

right now im not touching anyhting just taking in some info from mr burton but cant find any of the components he is referring to

Re: samsung CRT security monitor wont power on model ssc-12

ok i found u101

i dont have unassembled so its hard to see and the board is darkened/burned in a lot of places due to heat from components i suppose

I'm not certain that the schematic is an identical match for your board. I can see C501 but not C502 in the diagram
.
Best to post pictures to show what they are like.

For your safety please note carefully what is said in the schematic above on Page 3, Items 14 & 15.

and i dont have a pc101...i do have a pt101 with 4 legs...black small rectangle shaped..surface mount part

[shelby5041]

Re: samsung CRT security monitor wont power on model ssc-12

on my board c501 and c502 are right next to each other and there is a larger size diode D501 in the middle of both

it does seem a lot of reference on the schematics i dont see on my boards...some i do some i dont

thats whats making it difficult for me...and i think some of the parts are labeled differently

If you can check that one. I suspect it's the same.

It looks like the schematic may be different so what is the full model number of the TV and is there a part number on the power supply board.

Re: samsung CRT security monitor wont power on model ssc-12

the model # of the monitor/system is ssc-12m

[shelby5041]

Re: samsung CRT security monitor wont power on model ssc-12

i believe your serv manual is for my unit

[shelby5041]

Re: samsung CRT security monitor wont power on model ssc-12

there are no part# stickers on the board

all i see is
mm-1245 ver 5R4

this looks like a generic multi use board lots of spots with labels but no components there

Re: samsung CRT security monitor wont power on model ssc-12

The linked service manual is for a 12c version and the 12m version so should be correct

Re: samsung CRT security monitor wont power on model ssc-12

and sorry i cant give you a good pic of board there are too many wires and pic tube in the way as is

[shelby5041]

Re: samsung CRT security monitor wont power on model ssc-12

yes i know but it doesnt seem to be 100% accurate as compared to my board

[shelby5041]

Re: samsung CRT security monitor wont power on model ssc-12

and the pt101 looks like 2 legs are on the HV part of board and 2 legs are on the low voltage...there is a dashed line going through the middle underneath....

am i seeing that correct?

[dick_barton]

Re: samsung CRT security monitor wont power on model ssc-12

Posting a picture would help but I believe it is. Two legs on the Cold side and 2 legs on the Hot side

[shelby5041]

Re: samsung CRT security monitor wont power on model ssc-12

its hard to post photot since there are wires and pic tube in the way
