Back light inverter caps

Hello Sorry to bother you but Ive been trying to find information with no sucess for the values of the output caps to the 4 cffl's in a Liquid Video A170E101 Monitor's inverter/power board also the one xformer is open and needs to be replaced. I took readings on all the output caps going to the CFFL's and they all appreard open w/ a ohm meter. it has a inverter board Sumida IV90110/T a 19v input. I also wonderd if the transformers could be replaced with the piezo kind and would a lot have to be modifyed for that type to work? All of the caps are surface mount I desoiderd 2 of them. I am not sure if they are ceramic multi-layer caps i just have to look at them in a magnifying light these have no values on them at all. I hope you can help me I can pay you for the info if I get it to work too. I am a maintenance / tech person I understand electricty not too much electronics but i can fix some of those problems. Thanks Ken

Hello,what is the numbers on the board you have and what revision is it? I have a non working monitor that powers up but has a bad raster board which displays vertical gray bands on the screen. power bd,inverter bd case, screen,and control bd are all in good cond.I may be able to get you a value on the caps or sell you the unit for spare parts. I am not going to repair this unit like I normally would most others.spuds619 [email protected]

Samsung PN43E450 lost all video & menu while watching. Audio works. Stand-by light works correctly in off & on. No clicking. How do I identify bad board w/o test equip? Thanks, Doug

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.

Lcd tv that when on for 10 min the snd will stay on and the pix will go off could it be the inverter?

if the sounds still there and no back-light that is inverter board if have back light its t-con board..
if the above mention are all out..


That problem is usually cause of faulty capacitors on the power supply board..


Just follow this instruction to fix your TV..


1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Where is the inverter board located on the element flx-3210? Is it somehow combined with the powersupply? I've taken the TV apart and have found everything except a part that resembles an inverter...

Yes, inverter circuitry is combined in one board together with the power supply circuitry. It is beside the connectors of the power supply board to the mainboard. You can see two high voltage transformers, these are the one producing high voltage feeding the bulbs...

There is audio but no picture

Hello!!!

Your problem is caused by the bad Inverter board. Inverter board is the one that responsible for the back-light which is causing by not having a picture...If you don't have a back-light your TV it is of course no picture but everything is good specially the sounds.. The best you can do is to do the following: ...First is to open the back part of your tv so that it could open. ...then find/look for the inverter board.If you are not familiar with it you can find it on the you tube by typing "how to replace inverter board". ...then Just replace the inverter board with the same type & value to fix your problem...


I hope this information will be helpful...If you have any clarification or other query just add a comment.. Thanks for using fixya..

Good day!
The problem of your TV is in the back light.
Follow this procedure of troubleshooting to your problem.
  1. Open the back cover,remove all screws at the back.
  2. Plug-in the power cord then power it ON.
  3. Check the input supply of the inverter board.It should have 24vdc.
  4. Then if you have input voltage of the inverter board.Check the output of the inverter board it should have 500vdc so be careful its high voltage.
  5. When your inverter had a output of 500vdc.It could be the cold cathode lamp is busted replace it.
  6. If the inverter board have no output of 500vdc but it have a input of 24vdc.Replace the inverter board.

Vector 2500 watt inverter red led fault light no output. Model veco56d.

There is a fuse on these things at the back of the case. Could be in a slide out plastic holder, or in a round holder with a knurled screw or bayonet type cap. If this fuse is not blown, then the news is not good.

Sanyo ce32ldy1b lcd 160gb black screen with sound

It sounds like you have a power supply problem, this powers the inverter! Where you just replaced the inverter, we could assume it is good! Look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). The power supply can fail on some output and be good on others. Was the back light inverter new? If all else fails, see if you can return the back light inverter and get another! I hope this is helpful!!

No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.
