Toshiba 42HL67US blows fuses.

That sounds like some kind of mains surge could have damaged the TV. Also some generators can put out too high of a voltage if the load is suddenly removed.

Measure the capacitor with a ruler, then we can suggest replacements, cost should be less than $10 total.

Tell your dad to have some load connected to the generator output all the time, 100W lamp will be good. The regulation of the generator is very slow and the output voltage can swing wildly when it first comes on with no load.

8.5cm diameter?? Sure about that?!

Re: Toshiba 42HL67US blows fuses.

this is my dads tv.. he said that what happened...

power failed.. then his generator came on.. tv worked.

when power came back and generator powered down and house power(ac?) came up tv stopped workin.. that is all i had to go by

it is 200v 560 uF and i do not have a way to measure.. but.. it is about the size of a quarter in diameter.

other number on it.. KMQ 77s108? nippon chemi? 105 degrees

found tape measure.. 2.5 cm tall NOT including legs..8.5 cm diam.

dont you mean 8.5mm diam?,jeesh sounds more like a nuclear warhead

Re: Toshiba 42HL67US blows fuses.

where i got 8.5 cm.. i measured around the cap with a measuring tape.. if only across...approx 2.6 cm

That sounds more reasonable!

about to order.. one question bout this one u sent me link to...

it says 85 degrees.. and mine says 105 on it.. is that a big diff?

Re: Toshiba 42HL67US blows fuses.

Good point. For better reliability, may be best to pick this one:

(it would only affect the reliability in future.)

Oh, and check the lead spacing will fit too.

just got part about an hour ago.. installed cap..ty so very much.. works great...

Excellent to hear. Tell your Dad to heed the advice about the generator -- next time it might not be so easy!
And this should be a clue to others as to why we insist on pictures of the actual boards (not stock pics) -- otherwise the bad cap may not have been spotted!

Nice. Glad you didn't take my initial advice

Testing the board for shorts doesn't take very long and is super easy. For any board, I can generally do it in less than 5 minutes.

Finding the short, however, is a different matter. Murphy says it was always be the last component you desolder that is shorted.

For a 19 inch Dell lcd computer monitor, there is a short on the logic board. I looked at the 20 or so small caps and I decided not to even bother trying.

As we always stress, pictures of your boards matter. There have been a few self proclaimed "professionals" that think there is no sense posting a picture of the board even when we ask nicely. Another easy thread to hit close window and move on.
