Follow up question on samsung tv model-ua40f6400ar power supply checked with output b+ and relay not clicking on/off if not connected to main board,posible fault mian board?


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary..

Xv dv180 is not working due to thunder effect. now i want to buy new dvd player.


Do you mean you had a lightning strike? Okay, well first check power to the device. If it doesn't have power it won't turn on. Secondly check to make sure there wasn't any surge damage. Smell the tray bay, the back end around the cord, or near any vents. If there is surge damage you'll smell a very strong metallic smell reminiscent of a copper penny.

If you have a melmeter or volt meter you can test outputs for correct electrical output while the device is turned on. If can't turn on you can at least read the power supply output if you open the device. Though doing so will void any warranty and you are at risk of electric shock, so be careful when doing this and only if you feel comfortable doing this. Look for the power ribbon cable or plug leading to the main board. There should be a list on the board next to the plug pins telling you what voltage should be output from the power supply.

If it doesn't turn on and the power supply is working fine (that is it's voltage output is correct) you have a bad board damaged by the lightning strike. Toss the machine and buy a new one as the cost to replace the mainboard will probably be near to the cost of a brand new device that'd be pointless to replace.

If the power supply is bad, go online and look up the model number which should be printed on the power supply. These are usually cheap to replace (20-50 bucks).

Ultimately, however, you must remember to keep electronics on a sure protector or power strip with surge protection.

Model # TH-42PX80U tv was on when a storm hit 'lightning' , on lite only blinks... is it a fuse ? or mother board?


You are better off replacing the power supply board. Usually the mother board will output a power ok signal to turn on the TV only when the power supply is working correctly (all voltages are within specs), similar to a computer, having said so, if you have the schematics you can verify those voltages being output from the power supply upon depressing the power button. The +5v stand by voltage is most likely ok, since the mother board is at least providing you with the blinking light. It is the +12V and +24V which are not being output, along with any other auxiliary voltages. I would suggest either having a replacement board (power PCB) installed or otherwise feeding the needed voltages by substituting those missing ones with a variable DC power supply, just to verify it. Follow above only if familiar with electronics and electricity. safety first!.

Hi. There was a power outage, now when I start my PC it just goes on for 5 sec's then shutdown.


I just replaced a power supply for someone whose house was close to a lightning stike. Although the power ma seem to come on a short in any of the outputs can render your computer unusable and could potentailly short out your motherboard too. If you have the ability to test the output voltages of your power supply here is a link to ATX power supply pinout voltages. Click HERE.

Wii power supply problem


I would buy a used/new one from the game store. If lightning got it, it's going to have fried more than just a "fuse".
