I have an Element tv that has no picture, good sound but basicaly a black screen. Do i need a didgital board or a main board?


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.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Repair Sony nsx-40gt1 tv, no picture, 2 red blinking lights where normally green. Is the power supply board bad, t-con bad or main board bad. Who sells repair manual?


Hello Eric,

shopjimmy has the circuit boards and gives live support..

Check out the URL below.

Also consider getting an anti-static wrist band... so you don't destroy good semi-conductors with tiny static sparks.

Further information on that is under "ESD"

I have a LG 50LN5600 LED Smart TV w/sound no/pic Have replaced the power supply board and t-con board. Main board only one left and research says that this would not be a main board prob. Any help?


If the LCD panel back light is not lit you have a bad LCD panel. If the back light stays lit when the set is turned on then you almost certainly have a bad main board since you have already replaced the power supply and T-con.

It sounds that the main power supply regulator board has the fault. Replace all the large electrolytic capacitors on that circuit board, or replace it with a new board as card basis.

The tv powers up for about 30 seconds and then the power light starts blinking fast and the tv shuts off i think it is the main board but any suggestions would help


Good day.

This the procedure that you have to do.

  1. Remove the cover of your TV.
  2. Power on the TV to apply voltage data.
  3. Check the power supply output.5vdc for main board supply,12v for the sounds and 24vdc for back-light inverter.
  4. If any of the 3 supplies are missing or got a voltage drop,there's a problem with your power supply.Check some leak/bulging top capacitor.
  5. If the 3 supplies are OK,the problem is on the main board of your TV.Replace it.

I hope this solution will be helpful.Thank you for using FixYa.Good luck.

Samsung 40" lcd tv with a broken internal lcd panel


If the screen is cracked, it will cost more that what the TV is worth. Are you just getting black screen but still have sound? Otherwise it can be the backlight inverter board is bad or it is not getting power from the main power supply section.

My Akai LCT3201AD won't turn on


Normally the end model numbers signify a revision. Your LCD screen should work fine in the other one. Manufacture's tend to keep LCD screens within the same vendors for specific models for cheap replacements =)
