Answers :

You did not mention if you had sound; if you do, then the inverter for the backlight or the backlight CCFL has failed. The inverter is often on a separate board since these are often outsourced.

I have a TH50PX60U with the red light flashing 10 times. I went through the diagnostic flow chart to where it said replace the PA and DG boards. I replaced both and still have the 10 flashing lights. SInce that flow chart didn't seem to work I started checking the feeds from the power supply. I noticed on the PA10 that as soon as I plugged in the AC, the voltage read 15V. Then the voltage started dropping fast and went down to zero. Is this normal or should the voltage remain at a cons

I have an element TV with a MLT070A power supply board. I'm not an electrical guy, but a technician came out and showed me the bulged caps and said that was what's wrong with the TV. He said he couldn't get replacement parts (I think the whole circuit board)but maybe the bulged cap components could be replaced by someone. I don't want to junk this TV and wonder what I should/could do. They're going to send me a $350.00 check for the extended warranty I paid 650 for the TV and 150 for the Cir

Almost all monitors will accept a 60Hz signal at almost any resolution, however I suggest 1024 X 768 at 60Hz...then you can try higher frequencies such as 75 Hz or more after you have established that the unit is functional. ... Gateway FPD2185W 21 in. LCD Television
