Re: Chasing the 14 blinks on a Panasonic TC-P42S30

Ok thank you for the reply. I'll replace the IFGBTs with what I purchased. I might be able to track down the fet down at a local shop.

I'm away from the tv right now but when I get back at it I'll remove the Q600 from the circuit and test the way I normally do.

I know that in circuit readings aren't always accurate and you have to pull the component before you truely know so I'm going to test everything I pull first.

Ok sooo the fets are bad. The ones at q401 q402 q421 and q422 and q600. I have a pack of FGD4536, however it looks like it'd only be fit to replace q600 and that I'll have to order others for the q400s

Thanks for the reply. When I write questions like this I always like to write out the basic stuff so I'm not missing stuff that's why I included the beeps . I'm assuming the IC chips are tough to track down.

I haven't done your tests yet I know the ribbon connections on the sn board are all good. I checked the front not the backs though. I'm assuming the sn and sc are integrated in my model because I've seen them separate but I have one large board on the left.

I've googled the fets you referenced...

Hello all,

I picked up this tv for free and am trying to repair it. I've replaced the SS board and have the A board on order after receiving the wrong one. I checked continuity of the SN board by unplugging the p board connection and placing one probe on the chassis and one on the Vsus in lead and got a Beep (continuity) when I check the continuity of the new SS board when installed it shows rising resistance (assuming caps charging). I checked the Fets and diodes on the sn board while in circuit some were continuitous some were not (no beep) when I plug it in the led is solid and...
