Re: VO42L FHDTV10A - fixed but flicker??

I replaced both inverter boards with the replacements.
Now I have to keep backlight over
90% or I see flicker

Also, if I turn on dynamic range I get the flicker.

Otherwise works fine ...!?

Anyone else notice this with 1.3 revision of these LG
Inverters?

Thanks
Andy

Hi,

I replaced the inverter boards (slave was bad- burn't out video chip)
put in the newer revision 1.3 boards.

Now if I put the backlight below 90% the whole screen will flicker progressively worse the lower the backlight.

Never had that problem before - don't need to burn my eyes out watching it

any ideas? power supply issues?

Thanks in advance,

Andy

Re: VIZIO VO42L No picture, No Sound

Thanks - is there a specific way the little flat cables come in and out of the connector on the board? does the connector open up - I can't seem to get it to open....

Re: VIZIO VO42L No picture, No Sound

Hey Guys,

New here - good discussions!

I have same Vizio - same problem!

turns on, goes white - no picture.

I have checked out all voltages - ok - replaced power sup fuse - just in case - have good voltages all around and unit responds to remote.

Just read this thread and checked for the 8.5k readings - and lo and behold the slave inverter has one slightly low at around 7.3 and another really low - so I guess the chip is bad!

I also have ordered new set...
