Sceptre X32SV-KOMODO power light flashing

[lilmonk3]

Pickup this TV today.. Owner says it takes hours and hours before it will power on and it was powered on when I went to get it.. He said once he gets it to turn on, he dont like to shut it off.. When I plug it in the blue power light flashes constantly .. I was hoping to pop it open and find some popped caps, but not my luck.. I did go ahead and replace some caps that I had replacements for (Blue marks on top of caps in pictures).. Its been plugged in for 3 hrs and still flashing power light.. I tried to grab some readings and they are all wacked out.. I hear a slight ticking noise from the area marked in pic #2.. I dont see much on the forums about Sceptre TVs

Can you see a small cap on the primary side... around 10uF to 100uF, 25-50V? That is the startup cap and is a common cause of this problem. Especially if it works after warming up. The small caps virtually never bulge.

You can replace it with a greater capacitance, it will just take a second longer or so to switch on when you plug it in (not really a big deal for testing.) Just the standard blurb - same or greater voltage. Low ESR isn't important.

Check or replace caps by Q201, one of the cap is C209, I cannot read the designator of the small cap next to it.

This is the only smaller one that I have not replaced 33uf 35v

Re: Sceptre X32SV-KOMODO power light flashing

I dont have any of those caps on hand.. Will get some ordered unless I could get by with a ratshack one for it? The only smaller ones I have on hand are 10uf 50v

It would be fine for testing, but use a decent one for the final repair for longevity.

You can try 47uf or even 22uf

Re: Sceptre X32SV-KOMODO power light flashing

22uF might be too small to let it start up all the time though. If you have to use 22uF, use two in parallel. More capacitance is fine, it will just take a little longer. I have a PSU where I used a 470uF for the startup, originally 22uF. It takes 2-3 seconds to turn on when you plug it in, but works fine otherwise.

I have a few decent motherboards that I pulled out my puters and upgraded to better MB.. I might take a look and see if I can scab one from there.. But for now The Big Yellow Bus is waiting for me to pick my kiddo up..

Excellent to hear you fixed it. I wish all fixes were that easy!

Re: Sceptre X32SV-KOMODO power light flashing

What size cap did you try? Did you try just 22uf? Better luck than the Westinghouse!

Re: Sceptre X32SV-KOMODO power light flashing

Started with a 22uf.. But then found a 33uf off a trashed PB.. Only problem I am having is that HDMI isnt working..I will dig into that after the kiddo goes to bed..

Yes I do hope to get that going.. I was thinking of donating that to the to the high rise where the elderly peeps live.. They could put it in there activity room and watch movies since it has DVD built in.

That is very nice of you, especially since you re-capped it, it is likely to last 10-15 years or more.

Re: Sceptre X32SV-KOMODO power light flashing

I have fixed 7 total donated 3 and sold the other 3 to cover cost..

Re: Sceptre X32SV-KOMODO power light flashing

Keeping stuff out of landfill is very fun and rewarding and if you donate to a good cause it makes it even better. I would do it more often if I could afford it, but I'm broke at the moment. (Student life... budget of about £10 a week to survive on.)

I had the same problem, changed small cap and now it works
