Television would not power on one day. no sign of any problem previous to this-it just wouldn't turn on . I started troubleshooting by confirming voltage present at the outlet it was plugged in to , then checked continuity across the power cord and from the power port on the unit to the first fuse(f1) and across the fuse itself. all checked out ok. what should i do from here? tv is a SOYO DYL032D LCD

My new Samsung UN65C8000 LED TV has an intermittent pattern of horizontal banding that is present probably 70% of the time and varies from narrow width banding to wider width at times.

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. I then hooked up both backlight inverters and turned the TV on and the blue LED on the Slave inverter comes on, but goes off after only a few seconds. What further tests could I perform to check which part is defective or what component is the most likely cause?


When you reconnect the inverter boards, when the LED goes off on the inverter board, do you still see 24vdc? You shuld also ty hooking up test lamps to the 24vdc to see if it will stay on.\012Right now I have a feeling the problems are in the b ... Flat Panel Televisions

I bought a LC DVD 199A in November for a Christmas present. Until today, I have not tried to used the DVD player because I haven't really had a chance. I put the source mode to DVD but the DVD won't load, I did press lightly, the DVD went in only part way and I removed it. Why won't it load? Also, it goes from DVD mode to TV mode in a matter of seconds which is frustrating as well. What can I do. Of course it is out of warranty. Help? Patty
