Alba TV 32880HDF Stand by probelm
I have an Alba TV that when plugged in the stand by light comes on for a few seconds, goes off as if its searching for a source then no picture. The picture sometimes comes on but probably 1 in 20 attempts. I have replaced most of the capacitors but no change. Any ideas?

Re: Alba TV LCD32880HDF Picture issue
The backlight doesn't come on initially. When first plugged in the stand by light comes on. The stand by light then goes off as if its searching for an input but no backlight or anything. I've just plugged it back in and I now have a picture. Its a very intermittent fault.

I've replaced most of the capacitors on the board. It comes off stand by thinks for a bit then I have no picture and it stays off stand by. Now and again it comes on. I've checked the voltages through the board and it all seems fine. More scratching of the head required.

Re: Alba tv lcd32880hdf - power PCb issue
Edit to previous post. I plug the tv in. Stand by light comes on, blinks a few times, stays off and no picture. Sometimes a picture is displayed but not very often.

Re: Alba tv lcd32880hdf - power PCb issue
17pw26-3 v1. I have purchased another power board on eBay but it's a version 4. The only noticeable difference between the boards is a 1000uF 35v capacitor on v1 and a 50v on the v4 board. I'm picking that board up next week.

Alba tv lcd32880hdf - power PCb issue
I have an Alba tv which sometimes comes off stand by and I have a picture but often than not the stand by light flashes and stays on stand by. I have changed the capacitors but no change. I have checked the diodes and all seem to be ok. Any advice would be greatly appreciated. John
