Philips 42pfl3704d/f7 No power at all


its definitely the fuse. you have to go to the phillips website and type in your model number to get the right fuse. I went thru 3 different fuses and they all blew right away. phillips website sells the right ones 5 bucks each. Get it here and it will save you trouble trust me.


If nothing happens no light or sound when you plug it in to the wall it is definitely the fuse. mine was a T8AH250VP. You have to be sure to get that exact fuse. every letter exactly like that. there are a lot of similar fuses that will blow the moment u plug it in.

Hope this helps took me a month to figure this out. I was going to buy powerbaords for no reason. fixed my 42 inch phillips for under 10 dollars. couldn't be happier. Also always run your tv threw a power ack. If you plug directly to the wall your fuse will blow frequently.

42pfl3704d no power


Hello
The power supply regulator board to your tV should be suspected. It has an overload fuse [ a glass cartridge type] fitted on it. Check this fuse first, after opening the Tv. If found opend, be sure that the power board has some kind of short with its components.
It is best to get this board replace as card basis, rather than making 'surgery' to it, as the components with it will be very difficult find in open electronic spare part market. You can buy this baord form the atuthrised service center for Philips at your town.

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
T10AH250V

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

Click...pause pause pause...click...nothing.


there should be a soldered in fuse in the convergence IC input chain, usually fairly close, if there is an inductor coil in the chain, look for the fuse just upstream of that. Each IC will have a fuse, they look like resistors, but are usually solid color, white, light blue, or light green. Check those for opens.

If you find an open, you can bridge it with a fuse of similar load capability, just to see if the set will power up. If the fuse blows again, look for solder bridges in the IC joints. I know you were careful, but it's really easy to get a bridge, or perhaps overflow the solder to another trace on the board.

In lots of cases, when the IC goes, it takes the fuse with it, and you don't find out until you try to power it up.
