Check and replace damaged component/s at its back-light inverter stage circuit, or replace the back-light inverter board. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience.

Testimonial: "I was in the trade until 1999 but have had no experience of LED displays. Like you I have gone for the back-light board. there 2 flashes from a component on this board when switching from standby to on. I am looking at this TV as a favour for a friend so I don't want to go down the road of trying to source components. Friend said that display did come back on for one day so I was hopeful that this was a dry joint but maybe thats a thing of the past! Thanks for your help"

Toshiba 37X3030D TV. Screen fails to light, sound OK.


That'll be the inverter board. It might be the 6632L-0490A made by LG Philips. If it is, you'll find the 2 capacitors have leaked and a bit has blown out of the chip. The inverter board is hidden behind the main board on the 505 model.

Sound but no picture


This could be a problem in the vertical sweep circuit, as when the vertical circuit fails, The video or screen will blank out so the picture tubes do not get damaged. In this chassis, I have seen the convergence IC's cause this, or the capacitor in the sweep power supply that feeds the voltage to the vertical IC has failed and blew out the vertical output IC. If you have no solid state repair experience, play it safe and call in a trained tech to assist you in this repair. Good Luck.

In what way is the screen broken? cracked, distorted picture, no picture but has sound?

If it is cracked. Replacement of screen is expensive. Cheaper to buy a new TV.
If Distorted. Parts linked to the screen can be the culprit. Most common part to fail is the T-con board. Main board may not be sending signal to the T-con board.
If its no picture but has sound. Back lighting has failed which could be several things that can cause that.

without any other details besides "broken" it will be hard for someone to help with diagnosing your problem. We need symptoms like. has sound but no picture. Picture has horizontal or vertical lines. part or half of the screen is black, black borders don't count. Hope the info here has, in some way, helped bring you closer to what to do with your TV.

Laptop is on but screen is black


Try an external screen. That will exclude the motherboard. Shine a bright light at the screen, if you can see a picture, the back light has failed.

Toshiba regza has sound but no picture.


Hello: One solution to see if the picture is there and you just don't have any back lighting is to take a flash light and shine it at the screen you if you see a faint picture in the background then the inverter boards has failed, and you have no back lighting. If you see no picture then more then likely the Main control board has failed or the power supply has problems.

Display IC seems to have gone. It will be a replaceable module. Only you have to figure out which one it is. Such thing happen in electronics. Look for any burnt or bulged IC.

No Picture - No Sound - Pilot lite OK - hear speakers 'blip' when turned on


Toshiba did have a problem with a protection ic that would fail. It is possible that this is the problem. But some trouble shooting will need to be done buy a repair shop.
