I have a sharp 37" lcd tv,model # lc37sb24u. no pix or sound, power lite comes on about 10 seconds then power and opc lites alternate on and off. thanks RON


This problems very common in Sharp LCD tvs.The Tuner signal board have problems,every times the power LED,OPC LED lites up,just push the power button on again,wait see if the LCD backlight lite up and works,not the Power lite and the OPC lite LEDS flashes again.You,just have to push the power button again,sometimes u have to push the power button at least 6 or 7 times to get the Power LED stable,and then LCD backlight,come on than the tv work.Not sure,but if the Power and OPC lites keep flashing,after u pushes the power button at lest 10 or 12 times,and the LCD backlight dosen't come on and the tv don't work.I think,it time to change the Tuner board is completely dead.I have a Sharp LCD tv, I do this everytimes pushing the power button at least 3 or 4 than the power LED stable,and the LCD backlight come on than the tv work.Not a plaw in the power supply like those capacitors in many LCD models tvs,but some included Sharp Tvs is the Tuner signal board is not very good in design,use the tv awhile the Tuner signal board have problems recieving the power to it Tuner board components.

It takes an hour or two to come on blue light


Power supply caps should be checked out, look for caps with bulging top first, post back what you see so we can guide you further, see example of failed SAMSUNG monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Wii board


Make sure that you have synced the board to the wii (similar to a controller). You have to take the battery cover off the board and push the sync button. The blue light will start flashing. From there you need to open the front cover of your wii under the power button.

From there you start up wii fit and it will prompt you to turn on your board. You should get a solid blue light. If you don't, you may need to try syncing again.

Blue screen with flickering horizontal lines


Sounds like the 1000uf capacitors on the FMT board need replacing. This is a common symptom with that chassis. There are three 1000uf caps that fail on that PC Board

Monitor


Steve from Monitor Technology. You need to open the monitor and locate the inverter board.
Remove 3 screws,turn the board over and locate 2 caps,C110 and C111.Replace,820UF/35V
this will fix this problem.

Monitor won't turn on, just keeps flashing the gateway logo on and off


Unless there is inadequate ventilation, your monitor could remain on all the time with little ill effect. Actually turning on and off your monitor actually puts more strain on it then leaving it on all the time.

If the gateway screen is displayed for a moment and then just turns off, I believe the inverter board inside the monitor has broken.
What's actually happening is that somewhere in the board more voltage then needed is "leaking" in and the safeguards on the board turn it off to prevent damage.

I would go and get an estimate from a shop. If the price is within 30-50 dollars of a new monitor, get a new one.

Blinking red power light - set will not turn on


Were the pale blue lines real thin in a slight diagonal from bottom to top of your screen? If so you either have a bad component in the blue drive, Blue CRT socket or your Blue CRT is shorted.Try removing the blue CRT socket and trying to power up your set for a moment without the blue socket attached to the tube. Be sure the CRT socket doesn't touch any components when you try this. Let me know if the set starts up without the blue.
