    Lcd tv 20" Sharp Aquos LC-20AD5E-BK

    hi just picked one of these up it uses a CEF 300B-4 psu unit the problem i have the psu has no out put markings on it all the issue with the set is no picture so far i have stripped it down to the cfls and fired it up all the tubes light but only one end and only all half way maximum aon all cfls at the same time each power up gets less each time would you guys say this may be a psu issue not giving enough voltage to the inverter board? not giving enough voltage to run it or may be a inverter board issue? i dont want to spend too much on it untill i see the lcd is ok.

      Most inverters are 24V, what do you get on yours?

              Issue with Sharp LC-42SB45U
              by claytongarcia
              Hello everyone,

              I recently got a model Sharp TV, and I've noticed that the green power LED is flashing without any specific pattern. Additionally, there appears to be no voltage coming from the power board. I haven't observed any leaking or bulging capacitors, although the top of the larger capacitor doesn't seem to be perfectly flush with the jacket—if that makes sense.

              Has anyone dealt with this issue before?​

              Sharp Aquos Lc-80LE757U flashing Sharp on screen when plugged in
              by sefoster
              I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp...

              Sharp Aquos LC-70C6400U Half Screen Dark
              by scubacamper
              I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
              Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
              when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display...

              Issue with Sharp LC-47SB57UT
              by leorivers
              Hello,
              I bought Sharp LC-47SB57UT 6 years ago. I had to have a vhf antenna to pick up one local station(koco channel 5 OKC). It has worked great up until a week ago. Sometimes I couldn't get channel 5, now I can't receive it at all. I can hook up a digital convertor box I have from another tv and can receive channel 5.
              I think the antenna and cable is ok. I doubt that this would be the tuner board or possibly something else.

              Any ideas where I should start?​

              Sharp Aquos LC-60LE635E three blinks
              by klassic
              Hi community,

              I will describe my problem with a TV in those short following terms to be the most precise :

              What i have :
              Sharp Aquos LC-60LE635E
              power board DPS-162KP-1
              main logic board QPWBXF733WJN2

              symptoms :
              white led light logo at startup,
              after 2 minutes, blinking 3 times a row, repeating
              no backlight (and apparently no picture, checked panel with flashlight)
              no startup sound

              powerboard investigations :

              1-2 PNL : 0v
              3-4 GND
              5-6-7-8 UR : 13.15v
              9-10-11-12...
