I've seen posts where it says a fast blow fuse will not work, because in Degausing at start up, it will blow fuse. You need to use a slow blow type fuse, as slow as possible .

Where IS the power supply? I assume it isnt a unit like in a computer, since I don't see anything like that. Is it a board?

You will have to find the source of a major short in your power supply.Since it's a 5A i assume i imagine that's where the short is.

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

Unit does not power up. Opened unit and found fuse closest to power switch blown inside unit. Will replacing this fuse get my unit working again? If so, what would cause this fuse to blow? please help.


It is possible that the fuse was blown due to a surge and replacing it will resolve the problem, but I wouldn't expect it. Usually when the main fuse blows, the primary stage of the power supply has a problem and the replacement fuse will blow as well. This is not a cheap amp and I would suggest that it be checked by a service tech. A few quick measurements internally can determine the likely fault and should not cost too much as an estimate fee.

Please keep us posted.

When I plug the unit in and try to turn it on, nothing happens. toshiba sd-3980 dvd player


The internal fuse is blown.

It may be a replaceble glass cartridge fuse, or a fuse soldered to the power board.

Unplug, remove top cover, check and replace fuse. Radio Shack has reasonable coverage of fuses.

But - fuses usually blow for a reason. It could have been a power surge; it could be an internal failure. If the new fuse blows, it needs professional replair. Many of these are so cheap to make that it doesn't pay to repair them - replace it if the repair estimate is over 1/2 the replacement cost.

I had a power outage and now the tv will not power on. This is for a 55" Mitsubishi WS-55511. no green blinking lights.


Hi,

You may have a blown fuse. Unplug the TV and remove the back. Look for a small fuse near where the power cord goes in.
If it is blown that may be the problem.
Use a magnifying glass to read the AMP rating.
replace the fuse and plug it in. If the fuse blows again you need expert repair services.

If the fuse doesn't blow then try to turn it on.
If it turns on then check the operation of the TV.

If the fuse blows again or the TV won't work correctly then you need expert repair service to fix your TV.

You may be able to have your household insurance pay if it is damaged by lightening or a power surge.

Hitachi 50GX30B 50 in. Rear Projection...tv won't turn on since electricity went off & on


I have worked on several of this model for power surge damage. Usually what I find is a blown fuse, a shorted regulator i.c. and possibly a blown bridge rectifier(diode array). On rare occasions you can solve this problem by replacing only the fuse, but if the fuse blows when you plug the set in, you will more than likely find above mentioned parts have failed. The best thing to do is to call a repairman but if you have an ohm meter you can test it yourself:1.Unplug set and remove rear cover.2.Get spotlight and look closely at where power cord connects to circuit board.Small glass fuse will appear black if open usually.Otherwise,test for continuity, or just replace it.3.After replacing fuse plug power cord back in while looking at fuse.If you see an instant flash, fuse blew again meaning you will need to obtain parts in power supply and solder work will be required. That is probably as far as I can take this other than saying that you might first want to look at underside of circuit board to determine if major surge damage has occurred. If it has you will immediately know because it will have burn marks all around a/c power supply. I hope this helps, Russmann.

Instantly blows the 5 amp fuse next to the power cord plug.


You have a short in the power supply. Look at the regulator and or rectifier diodes. These are all on th primary side of the SMPS (switched mode power supply) the secondary side if shorted shouldn't cause a blown fuse at all.

Nothing works


The fact the set blows up the correct fuse is because it has a short ahead in the circuit,it could be one of the diodes(4) that is shorted,if one of these guys is bad all of them should be replaced with the exact replacement,ahead of them it should be a regulator and he is bad (shorted) it could have taken the diodes and the main fuse.The cause might have been a power surge.If you are familiar with tv service you can check the regulator and the diodes before you put in a new fuse,if you are not too familiar be safe and take the set for an estimate.If you suspect power surge or lighting damage it might not be worth repairing.Let Us know if you need more information.
