    I replaced convergence IC's but now all I get is a blinking power button.



    My questions at this point are, 1) Where exactly are the fuses located. I don't see anything labeled F850, etc.? 2) When I check the resistor at R7726, I get 2 ohm's, not 2.2 as appears to be the spec. I get this reading on the others as well. Do these need to be replaced too?



    Thanks.

In this unit it's likely the convergence amps are the cause. Those and possibly the 2.2ohm resistors (especially R7726) in the yoke return path - that's why you found the open fuse.

My toshiba TP50H15 color tv comes on then off and the light blink


The flashing power light on those Toshibas is usually caused by capacitors on the power board having failed solder connections. I have fixed them before by removing the power board and resoldering the capacitors. If you have experience with soldering and electronics it is an easy repair. Most shops will recommend replacing the entire board since their labor to repair it would probably cost more. Toshiba put out a service bulletin on this issue which a good technician should be aware of. (If memory serves the capacitors are C109 and C110.  Since your TV still turns on you probably haven't blown fuse F860 which often blows when these capacitors act up.)
If you would like further help with this please post a comment back here.

Toshiba 50H81 Has Power but No picture or Audio


ok i'm goin to need more info about your problem. you stated fuses and didn't say the location numbers of the fuses. Also, have you rechecked your fuses to see if they are all still good? 3 fuses sounds like more then one problem. once you tell us your loc#'s of your fuses, we can look into your problems.

Toshiba 50H50: No picture or sound, red light blinks


On alot of these Toshiba TV sets, there is a fuse called F860 that will blow and the light will flash because of bad solder connections on C 810, and C 809, on the negitave terminal. I have seen many of these boards condemed by non-authorized Toshiba repair shops. Good Luck

Toshiba 42H81 Blinking on and off light


Very common problems with this TV set. Toshiba even has a technical bulliten on this and several other models of tV set. The negitve terminal of C809 and C810 need to be soldered, as there are no eyeletes in the printed circuit board. This problem could also take out the fuse, F860. Replace if necassary. Good Luck
