Re: Hisense 50H5G - 10-code Flash Error

Well, I only bypassed one, but I do hear what you are saying. So, it sounds like everything may potentially be fine if I replace all of the strips to the point that no lights are left out? Any reason that this may be something other than a compounding problem of too much voltage on the remaining LEDs?

Thanks.

I have something strange going on that I cannot put my finger on, but I wanted to ask this forum their opinion before I keep making this worse. Bear with me, I've fixed several dozen HDTVs and various other electronic devices, but I am not an expert in this like some of you are. I know I made a few mistakes on this TV repair, but if there is a way to salvage this I would sure like to.

This is where things stand - First off. I am in a hotel on the road for work. You should have that picture in your head... lol.. I purchased a Hisense 50H5G off Craigslist for $25. It had a 10-code...

No one has any thoughts on this?

Re: Sharp Aquos lc42d6u power and OPC flash once together, then power light flashes t

I don't know how close I can get photos for you that you can see...hard enough for me to read them with my magnifying headset. Maybe later I can, but for now possibly these will work. The first picture is of the incoming plug from the power module to the slave backlight inverter on the right side, looking at the back. It has from top to bottom, 5 VBLs (which all have current when you first plug it in of the voltages I mentioned earlier, and also when you hit the power button again after the three...

Re: Sharp Aquos lc42d6u power and OPC flash once together, then power light flashes t

I ended up checking anyway... the power supply is only producing 23.65V through all leads I checked in the outgoing plug to the backlight inverters. The orange wire on the far left side is producing 0V, while the orange wire in the 5th slot from the left is producing 23.65V. Aren't both of those supposed to be outputting 25V? All wires on the left half of that plug are hot, while all of the wires on the right half of that plug aren't producing any noticeable current. What does this mean? Where...

Re: Sharp Aquos lc42d6u power and OPC flash once together, then power light flashes t

I've started doing the same thing in my unemployment...normally an archeologist, but times are slow.

I have in the last 2 months turned $50 originally invested into a now working 51" Phillips, a now working Visio 47" (both are my wife's computer monitors), a 42" for sale in a store, about six 40+" ones for sale as parts on ebay, two other fixed ones around the house waiting to resell, some books, some tools, and a multimeter. Not bad. I just got a connection...

Re: Sharp Aquos lc42d6u power and OPC flash once together, then power light flashes t

Eh..yeah...it is. Missed a number in there.

While attempting to start the TV - The Main backlight inverter board (on back, left side) does have 23.66V running through it, and I can trace the voltage through to most of the board. The two connections with power that run to the top ribbon have 23.61V on both. The two connections with power on the bottom running out to the ribbon on the bottom have 22.09V, and 21.40V to them. (Not sure if this is meaningless or not...seemed odd,...

Well, as the title goes, this is my issue. I cannot find anything on the error light as to what it means, but have come to the conclusion after 2 weeks of research and talking with others that it may be that one of the small components (can't remember the exact name) that are on the boards on the back left...the ones that are separate components for each CCFL...has fused, or shorted out, causing a power spike in that component when the TV tries to turn on. I currently believe the main board sends a signal for the power supply module to send power to these components during startup, finds an issue,...
