<< < (2/3) > >>

This may sound stupid but however i went ahead and orderd a replacement ic21 chip for the board thinking it may be down to this issue and went ahead removing the old blown ic21 chip from the board then solderd in the new ic21 chip and refited board thinking i would see anouther issue appear the exact same syptoms are happning as before,

But new ic chip is not blowing out dont know why the exact same problem is still there even though i changed over with a new ic chip any one got any idias as to why this can be happning,

Thanks for helping me out guys,

Ohm Supplies:
Fitting a new fsd is very unlikley to cure the fault,

What is the psu number? As stated by the other tv engineers, you need to fit a reapir kit, i'm the picture of the one shown is not for your set.

We design the kits with so many parts to sure the fault and increase reliability. We wouldn't do a repair kit with 4 caps or one ic which is the case with a lot of Samsungs etc.

You'll have something else short somewere casued by the fsd blowing

Thanks for the quick reply well this makes sense now,  i will upload a picture of the board so you can get a clear look at its numbers,  there is a kit for it im sure i orderd the ic chip from your self, cant remember need to look up my order lists,

Just to clear things up though i get no standby light at all when switched on the back light comes on sometimes but its irregular, on the odd occation i get the backlight come on with a bounch of multicoloured stripes come down the screen most of the time it just sits with no light on and plays dead,

I dident relise there was a kit actualy for my tv but when i took a closer at your site im sure there is one there,

I would order this with no issues it would be sad if this was not a fix though,

Ok so iv decided to just go with the option of handing the board to the proffesionals, To be honest i dont think im qualified for the job and have to give respect where its due, i would be happy to send my power board to Ohm Supplies and let them do there work on it,

I will contact him by email and set something up as there service seems attractive and reliable i mean the options are to go by these componants and for all i know solder them badly and not have the proper tools to know actualy where the board is faulting out,

The price offerd for a repair service is very decent i repair computers everyday and laptops and do the odd powerjack repair on laptops but i think im out of my leage with this one, thanks alot though guys,
