Re: Insignia NSL 32Q 10A picture problems

In the event that this might help someone I wanted to follow up on my last post. My TV's fixed with the new (used from Ebay) back light inverter panel. It cost about $20 with free shipping. The problem was that the left half of the screen started going black. The "please wait" dialog box appeared for only 2 seconds indicating a problem existed. Everything else looked fine. Hope this is helpful.

Re: Insignia NSL 32Q 10A picture problems

I've thoroughly looked over all the boards front and back and don't see any burnt areas or bad caps. I have read through the other posts regarding this model of TV and from what I can ascertain, I need to replace the inverter panel. Since only half the screen shows up when it is turned on, I'm guessing that this would control what is displayed. I have found a used board on E-bay and am considering getting it and trying it out. Would this be the best choice to try to fix this TV?

Re: Insignia NSL 32Q 10A picture problems

I just checked the voltage on the large capacitor and when in standby it's at 171 and with power on it is 410.

Re: Insignia NSL 32Q 10A picture problems

Do I need to do any further testing? Is this board okay with that voltage?

Thanks,

Terry

I tested the largest capacitor on the board. The markings are on the side that is glued to the board but the reading was 168 VDC.

I went ahead and went to town to get a digital multimeter. Ready to start testing when you are ready.

Re: Insignia NSL 32Q 10A picture problems

OK, here are some pics of the boards and components inside the TV. The TV is doing just what you said, it will show the "Please wait" for about 2 seconds and then goes dark. Before it would stay on for about 10 seconds and I could use it normally until the left side started to go dark. I don't have a digital multimeter but I can get one tomorrow.

Thanks...

Hi tom66, thanks for replying to my post/question. I have attached a photo, not real great quality, but it shows how the left half of the display is darker than the right. I didn't mention before but when I started having problems with the TV that I unplugged it and it has been sitting for about 3 months unused. Since then the symptoms are different in that when I power it up now I can't even go through the menu options or change the input. It will power on, give the "Please wait..." dialog box and when it disappears, then nothing...

Hi, I was hoping to get some guidance on how to start to troubleshoot this TV. I'm very new to this forum and have limited experience working on electronics but am open to any help I can get. I've read the threads and posts on this model of TV and so far haven't seen any of the symptoms that this TV has been displaying. It was working fine and one day the left half of the display went black. I would turn the TV off and in a few minutes turn it back on and it was fine for a few minutes to a couple hours and then again would start to fade. I hope it's something fairly simple and inexpensive to fix,...

Re: New Members - please post your introductions here

Hello everyone, I just joined this forum but wish I had known about it when it first started. I've always liked electronics since I started trying to figure out how to install a better stereo in my first car back in 1980, (Chevy Vega). The only formal training I have was in the Army learning how to troubleshoot wiring problems in power generators and how to hook them up to have power in the field. I really like to try to figure out why something won't work anymore and have a hard time just throwing something away when it can...
