Having problems with your Flat Panel Televisions ?

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...



Answers :

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:

From what you've replaced, it sounds like you need to replace the fluorescent back-light. This should be an even easier repair than changing the power supply. To find directions, search for the replacement part on google. Back-lights can go from anywhere from $60 to $300, depending on the brand, size, etc.

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 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.
