Question about Flat Panel Televisions
Hello, May I ask for your help please? I read a posting from you regarding an Olivea LCD TV and you suggested it's likely to be a capacitor problem etc. My TV is a Haier but has the same symptoms of a blue screen for 1 second. Having measured the transformer primaries I'm seeing 900 ohms, so have ruled them and dry joints out because the screen is full blue, no missing bits etc. The PSU is giving 25.3v on the 24v line either with or without the inverter connected. Otherwise the PSU seems fine. I can't see any bulging capacitors either, so this has me stumped! Thanks for your time, Ian - UK
I would recomend replacing the 11 caps on the inverter as 90% of the time its failed capacitors on the inverter. If you shine a bright light into the screen can you see the pic? Thats usually one of the first things I do when I suspect bad caps on the inverter.
