Have fuse in tv set blown. fuse says ff4ah250v what rating is it

Hi Carlos,
Thundering and lightening can damage your set in many ways. Sometimes if you are lucky, you escape with a blown fuse and some minor safety components damaged. Well open the back cover and see if the fuse is blown. If there is no other visible damage, try a new fuse of the same rating. If the tv works, well and good and if the fuse blows again, please consult the TV tech.
Good luck.

If your TV dead after the lightning, then your TV doesn't power ON with red light stays on lit you possibly have faulty main board.

If totally no indicator try to replace the fuse on power supply board if busted or blown (it is usually connected directly from power cord.

If the fuse still blown you need to replace the whole power supply board.

please rate!!!

if no any power light indicator at the front of your tv that was mean the unit is dead set or no voltage that is circulating in the main board and other boards.if you can remove the rear cover of your tv, the first place to check will be the power supply board if the primary fuse was blown. if the fuse is blown with darkened color that was mean has shorted component either in the main board or in the power supply unit. if the fuse blown with clear color just replace with the same rating.

Unplug tv and let it set for a couple of hours. Remove the back panel, the fuse is located somewhere near where the power chord comes in. Remove fuse and replace with one of the same rating.

You can purchase it in any electronics shop, just tell them the rating Ex. 3Amp/240Vac you can see this rating at the cap of fuse.

yes there is a fuse.that is located on the main board.and that fuse is mostly blown and needs to be replaced. you can get new fuse at  www.radioshack.com at the rate of $2.

There is no reset button on these new sets,your set has complete power problem since you have no lights no clicks,this might have happen because of lightning or power surge,either one creates a lot of damage,if you are familiar with tv service you can check the main fuse,he should be close to where the power cord comes in,if you find the fuse blown it needs to be replaced with an exact replacement for AMPS rating and VOLTS rating as well as size,if the fuse is blown black we might have more problems ahead in the circuit and it will blow up again as sonn as you plug the tv back in,if it blows again it will need a more involved repair,the problem could be in the primary side of the power supply,if you are not too familiar you should seek the help of a servicer a least for an estimate but if you suspect power surge or lighting damage dont invest any more on this set and get a new one.

In most cases on the board under the fuse the rating will be listed IE: 4A, 5A etc.

maybe you have a blown fuse,try to have a look first inside,if you have a blown fuse then replace it with the same rating,if it blows again replace your power regulator

I would think any standard fuse with the same rating would work. If your fuse is blown you also have something shorted in your set. You could try one and if it too blows then you'd need to have it checked out. Stargazer
