Having problems with your Flat Panel Televisions ?

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



Answers :

Next is check the power supply section/board replace all bulging capacitors from the power supply.use the same value and rating of capacitor.Resolder also all the components from the power supply.re tighten all the connectors..you can also replace the whole power board you can order it online.in the meantime try first my first solution then post back if it doesn't work.good luck!

This unit is practically brand new, has no dust nor dings nor damage on the unit anywhere, not even a scratch, but I haven't been able to get the unit to power on. Power cord is connected.

I live in a house built in the 1890's, and last year there were 2 different tornados ,within 2 weeks of each other, that blew over trees on top of my power line twice in 1 month. My TV hasn't turned on since then. Is it the fuse I need to be checking? Should I replace the power cord, maybe just the cord is fried?

Doesn't power up. Relay clicks several times, several seconds apart. After third click, power LED blinks three times. The OPC LED blinks once when the power LED blinks the first time. LED blinking pattern repeats every couple of seconds. Opened up TV to check capacitors. All look good. Purchased service manual, but there weren't troubleshooting steps for the power board.
