Re: Sanyo DP55441 - Replaced parts still no picture
**UPDATE**
Sorry for the missing pictures. I deleted them forgetting they were linked.
Heres where we stand. The TV powers up and looks "great" with the one side inverter not plugged in.
100% the problem is the left inverter. The question is, is there a way to test which part of the slave inverter is not working. I dont want to dump 50$ to replace them both if i dont have to.

Re: Vizio Model VP50 HDTV20A
if your lucky enough to take a look at it before buying, then i would say 50$ sounds about right.
Just make sure you know whats wrong with it, no need to sink a bunch of money into it.Leave a comment:

Re: Sanyo DP55441 - Replaced parts still no picture
Would love someone to direct me to the next step. Looking to figure out which part of the salve inverter i need to replace.
Some other information that might help, When i unplug the top one, and i plug in the ribbon cables back up and power, when turning on, the whole backlite flashes on for a second then off again.

UPDATE UPDATE!
Progress, so after this tv has been sitting i decided to retest the inverter boards. This time i disconnected the ribbon cable AND the power cable from each different sides.
This is what i get

So the Right side inverter is unplugged from power AND the ribbon cable. It shows picture but as you can see the colors are TERRIBLE. The original mainboard was plugged in, so for kicks i replaced the board with another one i ordered.

First, apologizes for not getting back to you guys sooner. Been traveling, secondly thanks for the reply, im truly at a lost and am looking for all the learning experience i can get
I DID, unplug the inverter from one side to see if i got a back-light. Nothing.
Actually i did not know this. That's a relief if this is the case. I wouldn't think the tcon board is the issue then.
So the next question is, whats next. I will be busting out the multi meter this weekend...Leave a comment:

Re: Sanyo DP55441 - Replaced parts still no picture
but that doesn't explain the no picture. Plus i have disconnected the power to one side of the inverter (and ribbon cable). still same symptom?
Do you have any input on that?...Leave a comment:

Sanyo DP55441 - Replaced parts still no picture
Hello All,
Recently picked up a non-working TV for 50$ (sanyo dp55441) like all projects I was thinking it was be an easy fix. The previous owner said his kid knocked over the TV backwards (no cracked LCD) and then the unit would not power on after.
Opened it up and reseated all the connections. Saw that when you use the remote or the TV buttons to power on, ONLY the front power light turns on. (No backlite nor picture). Decided to replace the main board…..still has same symptom. So in a last ditch effort I replaced the power board….Still same syptoms. Im at a loss.... -
