Re: Can I save this board?
It was multiple attempts. Could my solder sicker have caused the pad removal? I am 0.032 rosin core solder from radio shack. Many of the joints came out good and tight, and look pretty clean. I didn't realize the pads were gone so kept trying to solder then in. I guess a better question is not can the board be saved, but do you think it likely that I can save it? Or should I drop the $130 on a board from Shop Jimmy?

Re: Can I save this board?
Thank you for your time and advice. I do have a lot to learn and practice. 60w iron was used. So I guess I need to order a new board.Leave a comment:

Can I save this board?
I have been trying to fix this board from my Vizio 50 inch plasma. I was successful with another tv, but I have had problems with 5 out of 20 parts replaced. It is probably just my amateur soldering skills, but I haven't been able to get good joints on these parts. No matter start I try, the parts are loose. I have cleaned and scrubbed, used extra flux to no avail. The wife is telling me too trash the tv. I am debating buying a new board ($150ish), but I want to fix this (and I admit save money). Does anyone have an idea of what I should do?... -

Re: Vizio VP50 HDTV10A Replaced 11 Caps No Sound / Black Screen
i replaced more caps (I think all of them by now). I replaced the board and plugged it in. I got my 2 clicks and was in standby mode. I checked the voltages as directed.
P800: Red RL-DN 0.03V, Orange 5Vsb 5.00V, Brown DET 0.00V, Brown 5VD 0.03V
CN805: Bottom pins0.00V
CN807 0.0V, 0.0V, 0.0V
CN802: 0V
CN803: 0V
CN809: 0V
I have a solder joint or two that are a bit questionable. When I put my finger on the caps in question, I do see a slight bit of movement at the wire/solder...Leave a comment:

Re: Vizio VP50 HDTV10A Replaced 11 Caps No Sound / Black Screen
That is great news! Congratulations. I will go back and finish repacking the last few small caps. Hopefully I will have success too. I got sidetracked by a needed auto repair that had taken my spare time this week And I teach a class Tues. And Thurs. nights. I should be able to complete the change out and have a new DMM tomorrow night or Saturday. I hope I have your success. Great job.Leave a comment:

Re: Vizio VP50 HDTV10A Replaced 11 Caps No Sound / Black Screen
That's good to know. I thought that you could only go up on voltage, but that the uF had to stay the same. I will check out Home Depot, or maybe order one from Amazon. I had one from Harbor Freight that seemed Okay, but have misplaced it during a move a few months ago. If I get this done and working I may start looking for another project. I'm new to this stuff but it is kind of fun and a lot less messy than working on cars.Leave a comment:

Re: Vizio VP50 HDTV10A Replaced 11 Caps No Sound / Black Screen
Thank you for confirming that. . I found that cap and replaced it. I am not sure if it is accurate, but have been getting low voltages. I replaced more of the caps, most of which seem to test Okay with meter. I did find one that tests bad. From memory I think it was the 100 330uf, a larger cap. I haven't had any improvement really. I plug it in and get a click, a few seconds later I get a second click. The LED flashes amber several times and goes to solid. As described in my last post. I don't know if it would be helpful...Leave a comment:

Re: Vizio VP50 HDTV10A Replaced 11 Caps No Sound / Black Screen
Hey I fixed my TV! A first for me, but it is the second TV that I worked on. What?
Okay. Here is where we stand now. My Vizio VP322HDTV10A died while I had the VP50 apart. I couldn't be without a working TV in the house for much longer or there might be a mutiny.
I sent for the parts, and after communication back and forth we determined what I needed for the 50" as well. The kit for the smaller TV VP322 arrived Saturday, so I immediately went to work. I had the job done in about 30 minutes. It...Last edited by bphodges; 04-05-2015, 06:29 PM.Leave a comment:

Re: Vizio VP50 HDTV10A Replaced 11 Caps No Sound / Black Screen
hello. sorry I haven't abandoned this but got caught up in another pressing project and later nights at work.
i have replaced 20 caps (all that were in the kit) there are still a few that I will request from the supplier.
I need a 10V 330uF, 10V 3300uF, 50V 10uF, 100V 330uF and a 25V 100uF.
I pulled a rookie move after removing one of the caps. It got mixed with the ones I had already pulled (long dull story).It was one that I didn't have a replacement for. I have a picture, maybe...Leave a comment:

Re: Vizio VP50 HDTV10A Replaced 11 Caps No Sound / Black Screen
Just one click. LED flashes 6 or 7 times then turns solid green. No second click. I will have to order at least one more cap. A 10v 330uf. Not in my kit. Thanks again.Leave a comment:

Re: Vizio VP50 HDTV10A Replaced 11 Caps No Sound / Black Screen
Thank you. So, just to be sure, I need to go back and replace the remainder of the caps (except the big ones) and then check 4 voltages with the tv in standby mode. I just reread my post. When it clicks the light goes from amber to green and stays green until I shut downLeave a comment:

Vizio VP50 HDTV10A Replaced 11 Caps No Sound / Black Screen
Hi, I am new but have read extensively through the FAQ and watched videos. Last night I replaced 11 bulging caps. All seemed to be securely soldered and properly oriented. When I plugged it in, the amber LED lot immediately along with a single click. The LED then alienated green for a few seconds and returned to amber. Upon pressing the LED changed to solid green accompanied by another single click. The screen remains black, and there seems to be no sound (I connected an antenna, and cycled the input switch). Historically this TV was bought from Costco, the date of mfg is May of 2007. It did have... -

Hi. I am new to this forum. I am a 50 something guy who has no electrical/electronic training, but I am a tinkerer.
