No power LC-26SB24U

[Ashroyer05]

I had no power coming out of the power supply (BA17F8F0102) except for about 0.6V on one pin. The voltage would read 3.2V for a second then jump around until reaching 0.6V. I found a shorted transistor (K10A50D) at location Q600. I replaced it and still nothing. I then replaced some diodes and an IC using a repair kit. I still get the same voltage. The through holes for Zener diode (1ZB36) at location D610 show continuity. The Zener itself shows no short. The .18ohm resistor next to it also shows continuity. Apparently they are in parallel. I do not see shorts in any other components.

Nothing to add to your diagnosis I'm afraid but:- Sharp are rebadging Funai junk now? That is terrible.

Are you sure that is Sharp LC-26SB24U? I have exact model here in my house.

Sorry, I have too many things laying around. The CORRECT tv model is LC320SS2.

The original model I posted is for sale though, minus the circuits.

Emerson, Funai, Sylvania, etc?
This one?

Re: No power LC-26SB24U

It is a Sylvania. Yes that would be the one. I didn't see that jimmys had one when I did a search or I may have just bought that one. I have too much money into this tv now so I need to keep trying to fix

I circled the IC I replaced. When I put the new one in the pads around the thru-holes got damaged. I looked for continuity from the pins the other points and it looked okay. I'm just not sure if maybe one pin should have continuity to more than one point so I may try and restore the thru-holes to see if that helps.

Thanks bud. The two cement resistors tested open so that explains alot. Ill post after i get them in.
