Re: Sharp LC-50LE442u will only go one once - sometimes

Just a follow up on my issue here and information for all...

[B]Solved: [/B]My power supply board (PSU) was just fine all along.
The issue was solved with a replacement main board as shown here

Ok here are the values I measured for the 4 small CAPS
Qty 3 - 10 uF 50v and Qty 1 - 4.7 uF 50v

Cap uF, ESR(Ohm) Vloss
10.3, 1.6, 0.9%
10.1, 1.5, 1.0%
10.2, 1.5, 0.9%
4.8, 2.4, 0.5%

These are Su'scon HG caps ( double checked this HG on all)
The specs are listed here[URL="http://www.su-scon.com/Templates/att/HG.pdf?lng=en"]http://www.su-scon.com/Templates/att/HG.pdf?lng=en[/URL]
but I cannot seem to find either the 4.7 or the 10 on these...

Re: Sharp LC-50LE442u will only go one once - sometimes

The 4 small CAPs seem ok. - I was hoping they were bad.

Removed and tested the 4 small CAPs. Qty 3 - 10 uF 50v and Qty 1 - 4.7 uF 50v
All tested via ESR meter 10.3, 10.10, 10.15 , 4.77 . Similar readings with my DMM uF and Ohm readings OK. (the black stuff feels like silicon and cuts easily with a knife)

I'm up for more ideas.Re: Sharp LC-50LE442u will only go o...e 4 small CAPs

Re: Sharp LC-50LE442u will only go one once - sometimes

Wow, that was fast. Thank you for the ideas. I will be removing those CAPs tonight and checking/replacing them. Hopefully I will be able to read the sides for the values and I hope I have some on hand. I'll admit, I did pass over the PSU, particularly the Primary side when I noticed I had, what seemed to be the proper voltage at secondary connector.

I have a Sharp LC-50LE442u that I can get to work once...

Well after reading up on suggestions here, discharging the caps, and holding the input/vol Dn buttons while plugging the unit, after about 10 sec release the buttons. The stand-by light is solid red. Pressing the remote power on button will turn the TV on and the stand-by light goes green. TV seems to work fine at this point, tested with TV Menu, HDMI and VGA/3.5mm audio.

Problem is when the TV is turned off. Press the Power button on the remote and the TV goes off and the Stand-by light goes red (as expected)....

Hi there, I've never really posted here but have always "read up" on issues/problems and fixes. I've repaired many LCDs, Power supplies, motherboards and some TVs. I'll be looking for some more knowledge for the BadCap fans in my latest TV project. Looking forward to sharing here too.
