Question about Sharp LC52E77UN 52 in TV
TV will start up but will only stay on for a minute or so.. Once off takes 5 min at least to convince it to start again.. Have checked cable box etc. narrowed issue to TV
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices.

Blinking codes details to many popular brand TVs are given. Surf the site with patience.

SOURCE: No picture, but power is on...
How many times does the POWER led blink per sec? (dont worry about the OPC)
2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)

SOURCE: No power on LC32D50U Sharp
bobnyc, Is set under warranty? How old is it? Did it display a "perfect" picture yesterday, and not today. How is or was the AUDIO. Can you hear anything or nothing? Is the SMPS power supply board a "COMBO" or is the INVERTER supply located elsewhere? To where do the CCF tubes connect to get power? Tell me, do u have a good DMM, 100mhz Ocilloscope, Isolation transformer, and soldering iron/ solder wick???? If have some answer to some these ??? contact me @ louie12fix on fixya or at lmistyrel @aol.com PS: I highly recomend use of digital cam to take pic's before taking stuff apart. Could help when reassembling.

In all the time that you have had the tv have you applied 2 firmware updates that some of the tv's need to avoid other known issues with the lcd in the future. These firmware updates are for the main cpu PH1UU112 and the monitor MD1UA104. I don't know if this is the case for you but it worked for me. Call Sharp at 1-800-237-4277.

SOURCE: TV won't turn on
the first thing that you need to do is to open the back cover of your tv.Go to the power supply section it is separate board where the power cord is connected.Using a multitester,plug in the power cord and measure for the output supply.see if the 5vdc ,12vdc and 24vdc are present..if one of this output is missing,replace the power supply board But if the output voltage are complete,replace the inverter board,It is a board that supplies the high voltage to the backlights of your monitor/screen....You can also try to reset the system of your tv by pressing the the small switch mounted on the main board press it twice while the power is on...tnx and good luck!
