RCA L26W11 Backlight Inverter Problem


\015 I purchased my TV refurbished from Overstock.com in August 2007. Last year (November, I believe) I powered it on, but all I got was audio. I searched around online for a solution, but I didn't have the time to properly look. The problem continued, so I moved the TV to another room where it would be out of the way.\012\012About a month ago, on a whim, I tried powering it on, and it worked. I was fairly certain that it wouldn't take long for it to start acting up again, and it did yesterday. After looking around for more information, I tried the "flashlight test," and I could see very faint red images. Searching around on here, I believe that means the backlight inverter has gone out, correct? I finally pried open the back of the TV, but I couldn't find any scorch marks or bulging capacitors on the power supply or whatnot.\012\012My problem now is that I'm not too sure how to access the inverter (assuming that is indeed what's causing the issue). I don't know how many screws I've taken out, but I can't seem to get to it. I've never done this before, so I'd like more help from someone with knowledge of this specific TV.\012\012Any help is much appreciated! Let me know if any more information is needed.\015

RCA L26W11 Backlight Inverter Problem


... RCA L26W11 26 in. HD-Ready LCD Television

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 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

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 a vizio vz37l tv. When i turn it on the screen lights up, however there is no picture on the screen. the sound works, its just no picture on the screen. I read on a couple of the posts on here, and figured the proper course would be to replace the t-con board. I just finished replacing the tcon board and still the same thing. I called vizio about the problem and they say that if the screen lights up then the problem wouldn't be the backlight inverter boards, that it might be as simpl

Toshiba 40rv525rz shut off while playing xbox. When it shut off i could see a small white line on screen then went black. Tryed to unplug it for 5 minutes and would not turn back on. All it was doing was flashing the lit toshiba emblem up and nothing else! Talked to a couple of people and they told me it sounds like a power supply problem! So opened up the tv and saw that the power supply had a burnt resistor and there was also sut on the backlight inverter so i ordered a new power supply and in

I have a Rca 26LA33RQ upon initial use screen backlights bright white slowly fadeing to black. I do not know that the speakers work because I have not connect cable to it.

My dynex tv has sound but no picture it happened a day ago i found that the problem might be the backlight inverter board if so how can i fix it


Test: You might see a pic by shining a bright light against the screen. (Halogen can burn a spot if too close for too long like 15 seconds). If so, you probably have an inverter, backlight tube or coil/driver board problem. Some of these units have a ... Dynex DX-LCD32-09 LCD TV

I have a Samsung LN40A550P3FXZA that is giving me problems. When I first started noticing problems I would turn the TV on and I would hear the power-up sound, the backlight would come on and then the red LED would flash a few times then the backlight would go off and it would repeat (power-up sound---backlight on---LED flash---backlight off). It would do this several times. Sometimes I would be able to get picture if I hit the source button on the side of the TV when the backlight first came

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.
