SOURCE: will not turn on or off

I had the same problem. I work for a mother board manufacturer w/offices in New Jersey and brought mine into our engineering lab after Samsung told me tough luck. Anyway, one of my engineers fixed it in 10 minutes. Essentially, he replaced the 1000uF capacitors on the power supply board with 2 cent capacitors instead of the 1 cent capacitors that had blown out on the CHEAP SAMSUNG POWER SUPPLY BOARD. You can tell the caps are blown via visual inspection. The top of the cap should be perfectly flat and a blown cap will be convex on top. Unfortunately, there are also 2500 uF caps by the same cheap manufacturer on the board as well and we don\'t stock that value for our products. According to my engineer, those will most likely blow next since he replaced the others with better caps, but I\'m getting samples of those and will replace them shortly. After that this piece of junk should last me at least another 2 yrs! It\'s been working for about a week now w/no problems. Hope this helps.

Your board numbers should start with LJ92. They will cross to both Samsung and LG. Oh, your model number goes nowhere, double check it.

SOURCE: Samsung LN-T4665F when powered on

You more likely to need to backlight inverter boards, thpower supply should have 24vdc for the backlight inverter board, the 24vdc power supply get the trun on command from the controller board, that is what should have been checked first. So look for 24v or measure it directly on the inverter board connector pin. The invereter board also has a couple surface mounted fusesYou can get the inverter board here but make sure to match the number: http://www.shopjimmy.com/catalogsearch/result/index/?q=LN-T4665F+&limit=100

SOURCE: Would an inverter from a Samsung Syncmaster 910MP work in a Samsung Syncmaster 940MW?

Hello,

The Samsung SyncMaster 940MW monitor has an issue with the power supply # IP-46135T going out. The flashing power light or not turning on are the classic symptoms of this issue. Check out our web site at: www.ccl-la.com We have a step by step repair guide posted that will guide to doing the repair yourself. It involves changing a few capacitors on the power supply. If you can solder then you should be able to do the repair yourself. If you don't want to do the repair we do offer a repair service for $35 plus return shipping. If you have any additional questions just let us know at: tech@ccl-la.com

I hope this helps, if so please rate our solution.

Samsung 60 inch lost video; sound and controls ok. Any idea??


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electro-medical.blogspot.com/

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Could the new main PCB and/or invert PCB be faulty or is TV completely waste of time? I replaced both main power & inverter or interrupt power PCBs now I have no power at all.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

How hard it is to replace by yourself main board Samsung LN-T4065


You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.
