be more specific. no power? no image? no light? if there is no led lit, power supply problem. if the led is on but the fan doesn't turn on when the power is pressed, either the dc fan is seized or a board level fuse is blown. if the fan won't turn on, usually the light won't either. if the fan is on but not the light, the lamp may be blown. if all is on and no picture, check your inputs.

Dynex DX-24L150A11 won't turn on LED light is not on either


Sounds like you are missing your 5VDC standby voltage from the power supply. You either have a blown fuse or a defective power supply. Did this happen out of the blue or after a T-storm???

I have a samsung LN-S3238D lcd tv. the unit is approx 3 - 4 yrs old. last night when watching tv the tv shut off by itself and will not turn back on. normally when the tv is shut off, the red led light is...


Hi replace the fuse in the wire connecting the mains plug. It's generally located within the 3 pin plug.
If you are lucky it maybe just a fuse blown out.
Thanks

I have a 1 year old Sanyo Vizon HDTV and was watching a show when it suddenly just shut off and would not go back on again. No storms or any other power surges and it is hooked up to a real surge...


Hello
If there is no power indicator LED lights up when the set is sitched ON, the power regulator section inside your TV is faulty. There is a fuse [glass cartridge type]; on the power regulator board. If this fuse blows OFF the set won't switvh ON of the front power light won't light up. Check this fuse first. You can locate it at its power switching regulator board inside, where the AC power goes straight to it after a filternig circuit. If the fuse is blown out, replace ti with same rating. It ratings will be marked either on its edge rims of on its body by colour code lines. Replace the the fuse; if it has blown out, and switch ON the TV. if the replaced fuse also gets failed, do not put any fuse after, the power supply section has some short with it. It is best to replace the power supply board as a card absis; rather than making "surgery" to it. Some components in it will be very difficult to get too. You can buy a new power board from /Vizio Authorised Service Center at your town. OK.

Pioneer 65" TV Model # SD-643HD5 won't power up.


I would suggest replacing the board itself, chances are what caused those fuses to blow is still faulty. did you check those fuses again after you powered it back up?

Rockford Fosgate Punch 301X not runing


You should verify some other way (with a multimeter or another amp/device) that your 12V is working at the amp. Then to troubleshoot the Remote wire, take a short lead of scrap wire and run it from the 12V power input of the amp over to the Remote input like a jumper. If the amp still doesn't power up, then look for and check the fuse on the amp. If there's good power at the amp, the remote input has good power, and the amp doesn't turn on, and the fuse isn't blown, then the amp is probably toast. Good luck!

Radio, dome lights and EVIC power problem


I found a paritally blown fuse. When the fuse blew metal pieces ended up partially making contact. After replacing the fuse everything worked great.

AMP WON'T WORK POWER SUPPLY?


that big coil of wires ytou described is the transformer for the switching power supply. Sounds like you over heated it and blew out the supply or the output section. From what you described you should take or send this unit into be serviced as there are no user serviceable parts in this unit except a fudse maybe and if thats blown theres more problems as thats there ( the fuse) just so the whole bloody thing dosent burn up your car! Good Luck
