Toshiba 46RV525U, Ceramic or Glass 8A Fuse

I have a Toshiba 46" LCD Model: 46RV525U that was given to me. The fuse blew and the previous owner removed and lost it. I'm trying to obtain a new fuse but need to know if it's Ceramic or Glass. T 8.0A H/250V is on the board. See photo of the missing fuse

You can replace it with a regular glass T 8.0 amp fuse 250V and you will be in specs with the original.

    Found a local TV guy that told me that I could do that, just use a 10A and it would be fine.

    No dont put a 10A in thats very dangerous because if there still is a problem that fuse wont blow untill it gets in excess of 10Ampps and that can cause alot of items such as resistors and diodes get smoked causing alot of extra damage. always use the same rated fuse if it then blows again the power supply has a short but installing a larger amp fuse can cause further damage in the event of a short.

SOURCE: my toshiba tv doesn't turn on and there is no

Look at one of the power supply output connector pin, there should be 5vdc all the time the minute you plug the TV into the wall outlet, if you do not have the standby 5vdc, nothing else will work. No sign of burnt parts, bad capacitors? You can get parts here:
Please post feedback what you find.

I also have this problem on a set that is a year and a half old. The repair man was here yesterday with some parts that didn't fix the problem...he said the screen needs to be replaced! Luckily I bought from Costco, who extends the warranty by a year, so we won't be out any money. They will be getting back to me with what they are going to or replace...depending upon what is most cost effective for them. I will be trying to purchase extended warranty for this TV, if repaired, or new TV, if replaced. Too many horror stories out there on all brands not to.

My bass amplifier requires a ceramic fuse T10H250V. Where can I find one exactly like it?


Fuse breaks when it has succeeded in limiting further damage.

Check for other possible shorted electrical and electronic


• Could be drive transistor , output transistor or both on the main amp.

But check for power supply and in the preamps also.

• Measure supply voltages,

• Check DC offset voltage

• Check idling current (main amp)

Isolate , and trace afterwards.

My Toshiba regza 46" doesn't

Here are some basic steps that will help you fixing the problem.
I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord -check the cord it might be opened (no continuity).This is due to frequent bending,pulling.2. Power switch- check for dry joints, open contact.3.Check the internal fuse- sometimes the fuse fail because of thepower surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have ashorted partsin the power supply, you may visit the link more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.
4.If you see that the fuse isintact, don't attempt to touch anything because there somefatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look fora professionalto troubleshoot the power supply. If you want to repair it yourself make sure that you have necessarytools and test instrument. First checkbadsolder joints(re-solder all cold solder),leaky electrolytic capacitor(sometimes it hasbulgedat the top but not all, you better have a capacitor checker), open/shortedregulatortransistor/IC(mounted in heat sink),open fusible resistor(caused by shorted regulator Transistor/IC), shortedzener diode.
You may also replace the power supply board, try online like and
Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.
Hope I helped you.
Have a nice day!
Thanks for using fixya.

Toshiba 46RV525U are JUNK!

The LCD panel is defective. They are expensive. Call customer service and they may extend the warranty for you if you complain enough.

My dead 42" plasma - power problem

I have same issue with Samsung HP-S4253 Plasma. The fuse is a Littlefuse (manufacturer they do not sell), I have search and called over 20 places and the latest is Fuses Unlimited but it is discontinued and they do not stock but they can order. I will not be able to contact them until the holidays are over. There most likley is a minimum order. If there are other fuses you need write down part #'s so you can fill the minimum if required.

If there is anyone out there that can help with finding these hard to find fuses it would be appreciated.
There are most likey other Plasmas or TVs that use the same fuse just have to figure out witch ones they are.

Fuses on Power Supply Board: The 8 amp is the one I require.
T8AH250V P

Break Down of Fuse Description:
T = Time Lag
8A = 8 Amp
H = High Breaking Capacity (Ceramic) 1500A @ 250V AC
250V = 250 Volts
P = RoSH Compliant
