Having problems with your Flat Panel Televisions ?

What is the difference between the backlight inverter and the voltage inverter?

\015 I have a Emprex HD-3201 TV and there is no longer a picture but there is sounds. I was told it was the backlight inverter. When I look up the backlight inverter it looks nothing like the part in my tv. So I typed in the inverter product number and it came up as voltage inverter. Are they the same thing and is the even the problem with my tv?\015

I'm looking for a backlight inverter VIT68001.95 for my DYNEX DX-LCD32-09. I've found many different backlight for this model. Does it have to be the VIT68001.95 which is currently in it or can I use a different one and what's the difference?

Viewsonic n4060w black screen, no video sound ok. So I've been reading this forum about the problems others have faced with this tv. I decided to purchase pair of inverter boards. After installing them the same problem, no difference. I swap the boards to see if I can find a defective one, nothing. I can see the black backlight on, I have replaced caps on the psw before. Can I suspect the psu once again or am I missing something?

I have an ELCHS321. My backlight started to flicker. The inverter board is JLS-05-32EI. I have the back open and noticed that the LED on the inverter board was blue and flickering as well. As the set warms up the LED turns white but still flickers. The LED goes solid white and the flickering stops. Is this caused by the inverter board or or the backlight. Is there anyway to load the inverter board output to isolate th problem.

I would suspect and check first the voltages going there to see if low when cold and come up and if they are moving up and down when it flickers----points to problem in power supply ... Element ELC-HS321 32 in. LCD TV

I have a RCA l32hd35d version A I can turn it on and it comes on and the backlight goes back out. The rest of the tv works and it has a picture if you look at it close. Just no back light. I have replaced the inverter and the problem is still the same. The blon pin on the inverter has 3 volts on it even after the backlight goes out The 24 volts is still there too you can keep turning it on and off and the backlight will stay on. any help will be great...

If you have 24vdc feeding the inverter board, the next signal you need to find is the BL_ON SIGNAL which will turn on the inverter board, it should be 3.3vdc or 5vdc on that pin (pin 12 on CN1 of the inverter board), see picture here:\015\012 ... RCA L32HD35D 31.5 in. LCD HDTV

I have a Vizio VW32LHDTV10A that produces sound but no picture. I have checked the main power board for 24v to both backlight inverters and 24v is present. I then hooked up both backlight inverters and turned the TV on and the blue LED on the Slave inverter comes on, but goes off after only a few seconds. What further tests could I perform to check which part is defective or what component is the most likely cause?

When you reconnect the inverter boards, when the LED goes off on the inverter board, do you still see 24vdc? You shuld also ty hooking up test lamps to the 24vdc to see if it will stay on.\012Right now I have a feeling the problems are in the b ... Flat Panel Televisions

I have a Samsung LN46A530 46" LCD TV. Lost my backlight and wondering if the two wire connectors feeding the R and L inverters is where I would meter for power, and if not what are these for ? Or is it the ribbon cable on the top left (it's pin ids are 1. 12v_cold, 2.FB, 3.FB, 4.GND, 5.GND, 6.LD, 7.LD). Would this TV use 12 V to power the inverters ??. The inverter enable is on (5V), so I assume it is either the pwr supply or the master inverter.

When I unplug unit for two hours, the screen comes on normally backlight comes back up and picture is normal, but changing the channel causes it to go dead again. Bringing up menu with remote is really sluggish and when attempting factory reset, it goes black. Vizio light on the front of the TV comes on and off when pressing power button,

I have a samsung ln-t4053h that had a bad caps. I replaced the caps and the tv turned on fine and i put a flashlight to the screen and the screen turns on but the backlight is on 10 and it looks like its not on at all so that leads me to believe the backlight inverter.
