Most likely your power supply is damaged and will need to be replaced. Sometimes, power supply manufacturers add additional "fusible resistors" to provide additional protection.

    Thank you. Is the power supply something a "real" amateur can fix or replace?

    replacing it isn't hard at all, just make sure you leave it unplugged for a while before handling it. This will give the high voltage capacitors time to discharge. The problem is the cost of a replacement power supply could exceed the value fo the set.

    I've seen brand new 19" LCD TV's for under $100. Also, depending on how you have your TV setup, you could have damage to the main board. Power surges can come in through the power cable as well as coax, HDMI, component and RCA cables.

WON TURN ON


For the first step, try using the button on the TV itself.
Secondly, check if the power cord is snug, and not burnt. Sometimes after a blackout, there would be a power surge, and that might burn your plug.

If both doesn't work, the fuse in your TV may be blown, or the Power Supply may also be burnt too. If this happens, you're going to have to hire an expert to help replace the broken parts.

Note that in some TV models, the fuse can be replaced by users. If this is your case, try checking the fuse to see if it's blown or not.

Tv won't turn on like it's unplugged but it's not


I have seen the same problem with my tv's and the like. Depending on the age of the unit, I could sometimes find a blown fuse inside (safety feature). Many electronics especially tv's are extremely fussy about power surges. Even times when I knew there was no power surge, I would find a blown fuse inside the unit, keeping power from ever reaching it's destination. Like you said. tv behaving like its off because no power getting through

I'd guess that the surge damaged some resistors on the internal circuit board, possibly a capacitor. You may be lucky if this has an internal fuse, in which case the fuse may have blown, saving the main components. Best course of action is to take it to a TV repair shop or similar to have it checked out

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.

AOC Envision L32w761 TV. Lightning strike. Now nothing. Power light won't come on. Checked power to the Power Supply board and have it fine. Replaced TV and everything in the system looks OK. Bad TV...


If you are certain you have a lightning surge, almost anything can take down your TV. First check the obvious, do you have power coming out of the wall. Is the surge protector good, if you used one? If you have answered yes to the these questions, you may have acquired a power surge in your TV. You may not find it in your TV. As I have said it may be anywhere in the TV. You will need to take this TV to an authorized service center. It would be difficult for anyone out side a technician to find the problem. Thanks for asking and show all hands of support!

Had a power surge into the house- the tv was not on a surge protector and i am wondering if the tv is blown out- or is there a fuse possibly that blows at a power surge?


hello kath... if the tv won't come on now the power surge fried internal fuse and possibly more. The least expensive way to get this repair is to physically take the tv to the repair shop. If they have to make house calls, the cost goes up significantly. Joe
