Firstline FS3201MHI SOUND BUT NO PICTURE

I have the same problem with the same TV. Did you manage to fix it? I have the inverter board in my hand and my 4511GH components look like they've been getting too hot. When the telly runs now there is a tick tick sound coming from a transfo on the power board (like its tripping out) and the backlight does not light. When I unplug the inverter board from the power board the ticking stops... that doesn't prove its the invrter board, but it fits with what I see as well as what you have found. So did you get anywhere?

Cheers,
Tom

SOURCE: Insignia NS-32LCD Backlight or Inverter bad???

If you've done the flash light test, it could be the inverter board became defective but it could also be that the power supply does not provide the +24VDC to the back light inverter board.
If you could do the +24VDC test using a voltmeter then we can say for sure that the back light inverter board is defective.
Let me know if you need further assistance.

SOURCE: faulty TV, no picture but sound present

Sorry can't solve the problem... yet. But I have exactly the same problem with the same TV. Sound but no pic, and a toko inverter board that has four 4511GH components that look like they have been getting too hot. I get a ticking noise from the power board when it is running, and that dissapears if I run it without the inverter board attached. Did you get anywhere with the fix? I am not an expert so don't know if it is as simple as replacing these four components althogh its the one between CN6 and CN7 that looks worst. Any help?

Thanks.

SOURCE: I have a NS-LCD37-09 tv. No picture or backlight

Your main board is faulty. I've done several of these but haven't been able to figure out which component is actually bad these yet. I've simply had to replace the board itself, and it fixes it every time. One thing you can do to get your backlights to come on (and so you know I'm not Jive'n you) Is unplug the three wire bundle that spans from power supply to main board. This will usually make the backlights fire up. I even had one that after I left it that way for a minute (with the backlight on) it suddenly started working again! But this was short lived. :-(
One time I even tried recapping the entire main to see it that would fix it. It did not. I think it might be something to do with the small chip labeled SL37HA37. It's a 16 legged bastard near the 3-wire plug I told you to pull. It's that or possibly the bigger IC near it that has a heat sink on it. The ball grid array solder joints may be faulty. Just guesses, if any smart guys out there figure this one out, be sure to tell the rest of us please!
Thanks, Chris Boise LCD www.boiselcd.com

Looking to fix Insignia ns-32e570a11 no picture, only sound problem.


Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

No picture but have sound


Hi,
Your TV have problem with the back light inverter board. This type of complaint can occur under two circumstances.
1.Faulty electrolytic capacitor in the power supply board
2. The back light inverter board.

If you have knowledge in electronics then check the power supply for any faulty or budged electrolytic capacitor. Have adde the picture of faulty electrolytic capacitor how it will look like. check the link. faulty capacitor .

If the are no such faulty electrolytic capacitor then you have to replace the back light inverter board. There is no repair possible with inverter board because its spares are rarely available.

You have didn't mention any model number of your TV. so its not possible to add the exact picture of the inverter board.

My LG HD tv screen suddenly went green. sound is


Hi,
I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs.
Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture.
If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it.
Thanks.
