Ahhh the noise maker comes to life again .. Ok my friend this is a common problem with this set If your lucky?? If you know anything about trouble shooting tvs then this is what ya got.. Try first to measure the Horizontal output transistor. It will meaqsure a few ohms between the base and emmitter. But the base and collector should measure about 450 to 550 olms on the diode settings onm the metter.if it measures shorted you need to replace the flyback tranformer along with the Horz output transistor. Now if the HOT( thats horiz output transistor)is not shorted then theres a little coil in the horizontal drive thats causing problems as you need to take out the coil from the PCB and scrape off the ends and reinstalkl it. also the horizontal driver tranformer as well as the resistor that feeds the transformer could be bad and thast is a 3200 ohm at three watts. if ya dont have a clue what I just said the sets gonna cost ya ariynd 200 to 300 to fix .. Is it worth it to ya>?????lol Good luck

Sharp aquos tv, model no. lc-70c-6500u, no audio, visual at power up, standby/power light flashes 2 times long, 5 times short, nothing else happens, what is this mean?

Sounds like main board fault. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

I have an Hitachi P42H401 72" my son was playing a game on his Xbox360 the othe day the TV was fine and has been in the middle of his game the TV screen went to no signal and the TV shut off and has been...

I did some research for you. This is a known problem with this TV. Remove the back cover, blow out all dust, then disconnect and reconnect all cables leading to and from the power supply. (Do one cable at a time). One of them is not making proper contact. // Your son playing a game is an interesting coincidence. The guy who figured out this ''fix'' had the same exact thing happen. Only in his case it was his niece who played the video game. // Best of luck to you...

Will ont turn on

In about 90% the power supply failed if the TV is not turning ON, needs to be unplug to make it work or it produces a buzzing noise through the speakers.
I repair these power supplies, if you need further assistance write to [email protected]
