Re: Hitachi LE55U516 Power supply issue
A couple of the pins are not connected and this was not my best soldering....Leave a comment:

Re: Hitachi LE55U516 Power supply issue
The PSON voltage is there, 2.8V. when i replaced IC9101 it worked fine for a few minutes, then it started blanking out before it finally stopped working again.
Typo.. Q9101,Q9102...Leave a comment:

Hitachi LE55U516 Power supply issue
Hi All . I have a beautiful Recycle Center rescue that has only 5V output and the Main cap stays at 160v even when powered on. From scrolling through this forum on a daily basis I remember that the problem is related to the PWM so i first replaced that IC (IC9301 - A6069H). When that didn't work I replaced (IC9001 - SSC9512S) and it powered on for about 5 min then back to the same issue. I'm close to the problem but I am having a terrible time figuring it out any help would be appreciated.
Images attached, the ICs for the affected area are listed in case you cannot see them clearly

Re: Leds
6916L-1987A is the P/N for the strip.. They are all on eBay.. I assume you talking about just the LED?Leave a comment:

FYI.. Vizio M49-C1
Just an FYI.. The voltages labeled at CN9101/CN9102 on the power supply (ADTVE1825AC7) are incorrect. all the +12V are actually 19V. I spent hours trying to figure this out and even swapping out another PS that had matching pin outputs with the correct 12V. a pic of the board from shopjimmy attached
Found this TV at the dump, new with stickers. the screen would work for a few minutes then go all white or red. Turns out the LVDS cable was not completely connected in the TCON causing it to act up. A strip of tape fixed all my issues, it's been running well since then.

Re: Samsung ln40a530p1fxza Loud screeching noise no screen
Any Main board like this, I ALWAYS replace the caps on C102 and C131. They are labeled NEx AS7. It uses a regular 47uf 50V cap. I just pull them off scrap parts i have laying around. That usually fixes the screeching and power cycling issues.
Hope that helps.....Leave a comment:

Re: samsung 46" LCD Tv loud static noise at start-up
47uf 50V cap of Cap on C102 (backside) and C131 (front side) of the mainboard usually fixes the issues for me. I've done about 12. you can use a regular cap for the replacement, the White stripe on the original represents the Positive+.Last edited by 102mm; 12-05-2016, 06:27 AM.Leave a comment:

Re: Sharp LCD screen noise
I had a 52" version with the same issue. it used a different main board though. I baked the main board in the oven and it fixed the issue for about a month. The issue now happens when you first turn he TV on but eventually goes away.Leave a comment:

Re: LG 47LN575V suspect bad LEDS - what spec LEDS can I replace with?
Flocko that is an awesome idea. I was thinking of doing the same thing, but i talked myself out of it.. I have a ton of LED strips just laying around waiting for the right TV....Leave a comment:

Re: Insignia NS-55L260A13 LCD TV Won't stay on
Not sure if this thread is still relevant or not, but I had the same issue with a Dynex DX-55L150A11 that uses the same power supply.. Replacing the power supply fixed that issue..Leave a comment:
