Acer AL2671W 26in problems: (1) sometimes sound but no picture, (2) or screen freezes pink etc. (3) or remote won't turn it on/off (4) or it gives up and says "no signal". Turning it off/on usually solves it temporarily.
Needed replaced the LCD inverter board.
Where do i find the c 280
SOURCE: Picture and sound out of sync
Had the same problem with a new "Insignia" hd set and my Sony receiver. Went to the TV inputs, scrolled thru the selection, which included the HDMI option. Choose it.................problem solved.
SOURCE: no picture on flat panel tv. has sound
Sounds like the digital control board, 6871qch038a Lg Digital Control Module subs to 6871qch038c. But that's just a first something I would check in this unit. Replace also capacitor C19, 630V big blue square cap very common failure for no video. You might want to shop this one thee are a host of problems with this unit that would certainly get some needed attention if a qualified tech were testing it and looked up the bulletins.
Good Luck!

SOURCE: flat tv, sound but no picture. have tried
I had one that had a black screen and fixed the problem by repairing the inverter. When I opened the unit I looked at the capacitors on the inverter board and found them swollen. I looked at the bottom of the board and found that the fuse had opened up. The caps were a cheap quality low temp variety 150uF at 25V I replaced them with 330uF 25 volt 105C caps. I then replaced the 2.5A surface mount fuse with an axial 2.5A pico fuse and the TV worked beautifully.

my 42" Emerson Plasma tv went blank. I can't see any picture but i do hear the sound?
