What else to check?
BIT3195G, BIT3713, BIT3715

I have done some testing and I am in a cross roads as to what I should do next. Did they really think he would datasyeet them the entire formula???

If I can get this working, I will absolutely change them. Check to see if it’s open. Well, I’m no expert on electronics.
I figured out what I didn’t do change three more of the caps and it’s up and running like a new monitor once again. Problem is that backlights arent working at all. Thank you for all the Help in Advance. What part did you change? I did the whole power on and check with a flash light.

Where else to look?
Badcaps Forums – Samsung b LCD cold start problem (inverter?)
Power light is on. Here’s the BOM from mouser. Dxtasheet for proper voltages at the inverter. Changing all caps on the power board, except the big one, fixed it. If these are correct, trace the signals from the connector to the inverter controller. Bad caps are still plaguing things inI have the same Samsung b, same problem I still will take some pics if I ever get some time. Thanks again for the responses.
Can we get clear and focused picture of YOUR boards? I bit3195 check that they exactly matched the old ones. Here are pictures of my board. Bright as datasheeg and stable too. It is not uncommon for manufacturers to make changes on their boards. Replaced picofuse with litle wire. The backlights come on and the screen is white.
Okay So I am a newbie. Well, looks like Last Chance Saloon,before the Backlights become the Main suspects,so I would resolder the Inverter transformers,and all other joints between the secondary and the Lamp sockets,eg the small Blue Caps etc etc. I had a similar problem with my Samsung B as well. There are other ways but this is maybe the best way for you. Any help would be appreciated and I will get some pictures of the boards.
Would the incorrect voltage contribute to this, or is my ccfl likely burned out as well? Others mentioned the fuse being problematic so I was looking for it to test it. It may be covered by white glue.
They looked as good as new. I replaced all caps and picofuse but still no backlight. Datazheet detail on ‘problem with Backlight’, would certainly help,to allow members to maybe help you,eg None work,they work sporadically, they go on and go off BUT Power light stays on etc etc etc. I will check dafasheet for the fuse, I tried to look in that area but could not see the code f, however that section had a lot of glue on it, so I’ll daasheet closer.
I’m going to check it out and see if its tests good. Thank you every one for all the great knowledge on this thread and on this forum. Symptoms upon turning it on were no reaction but the rapidly blinking led as well.
