Sceptre X322BV-HD*XVNO5 blue light only

[jumpingjoeusa]

My TV just suddenly went out. When you turn it on the blue light comes on only and then the only way to turn off is by unplugging TV.

Re: Sceptre X322BV-HD*XVNO5 blue light only

quick search shows the powersupply is subject to capacitor failure.

Re: Sceptre X322BV-HD*XVNO5 blue light only

is this the powersupply?

Re: Sceptre X322BV-HD*XVNO5 blue light only

yes that is the one. also I am not getting continuity from the ground at the plug in to the grounds at the connectors on the power supply.

Re: Sceptre X322BV-HD*XVNO5 blue light only

read the stickies, first posts in the list, and throw up some good clear pics. of each board and one of all of m so people can see how theyr all connected.

[jumpingjoeusa]

Re: Sceptre X322BV-HD*XVNO5 blue light only

I am having some trouble getting the pics posted here and am going to a faster connection location.

Isn' this another thread tat you already asked for help? Did you read the other thread that you already posted?

It is not good to post the same question on more than one thread, hard to follow.

Re: Sceptre X322BV-HD*XVNO5 blue light only

Sorry I have never posted before it is true that there was a vage earlier post that did not provide thr information needed. Thanks for pointed out the other thread response and its true I need to test on dc not ac will post more in the next day or 2 as I am out of town. I hope the pics post ok as I am new to thumb nails also.
Thank you

"KM" caps seem to be the worst for being bad while not visibly bad!
Replace them on sight!

[jumpingjoeusa]

Re: Sceptre X322BV-HD*XVNO5 blue light only

test results

[nomoresonys]

Re: Sceptre X322BV-HD*XVNO5 blue light only

yep, recap is a good place to start, can't test caps accurately without esr meter, replace then you can at least move on with testing without having to wonder if theyr good or bad.

I think you need to give us the valid voltage readings first since what you have shown on post 4 are way off.

Yes sorry about that. I have corrected that in a few posts up.

It better to post right in the page like you did on post 4.
The power supply is working from what I see in the spread sheet.
So you need to remove that black insulator sheet off the inverter board and give use good clear pictures of the inverter board, especially around the connector that goes back to the power supply board.
We need to see if it has any blown fuses on the inverter board.

Re: Sceptre X322BV-HD*XVNO5 blue light only

I hope this what you requested.. This the inverter board. I thought this lit the screen. I have and still a little ill. Let me know if the pics are right

Re: Sceptre X322BV-HD*XVNO5 blue light only

My voltage reading coming out of the T.RSC8.10B 12305 board going into the TV BACKLIGHT INVERTER BOARD - VIC91801.BZ seems to be good. My question is "what should my voltage be coming out of the VIC91801.BZ board (see pictured) pink & white wires?

Those are the lamp outputs - they probably run at least 1.5kV, with about 3kV start voltage! Unless you have a meter capable of measuring at least 5kV I wouldn't even try.

The lamps themselves are the best way to test if the inverter is functioning.
