SOURCE: No power at startup on Sharp LCD-32gd8e

Hard to diagnose some problems without hands-on. However, my guess is the power supply is fine, as are most on LCD's. The inverter board which powers the screen is the most likely cause of problems on that model set. Only other thing that i've seen is a shield that moved slightly beneath the main pcb. It moves because the putty that holds it in place was not rated at a high enough temp. and it simply turns to goo, allowing the heat sink to slide down and touch the main board. Three boards must be removed to find this problem. By holding down the power button on the set you may not be allowing the shutdown circuit to engage which means the problem could still be anywhere in the set. Sorry I can't be more help. All you can get is a guess here.

SOURCE: RE: Sharp Aquos LCD TV,

A component is shorting out, and the TV is auto turning itself off for protection. Usually it is a shorted out horizontal output transistor. Only a tech can fix this.

You have bad switches on the front panel. Press them 50+ times to release them. Failing this you will have to replace them. You can disconnect the front panel to confirm this.

Try to maintain the power button depressed. If you get a picture, then it is probably the same problem as this one : http://www.fixya.com/support/t274037-lcd_screen_not_stay

I have a Sharp flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;

Turn the tv on and the green light blinks and then turns off and comes back on then turns off again but the screen is black. What is wrong?


KDF 60XS955 intermittently turns off green light blinking then on after...
The frequency and color of the blinks will indicate the issue. There is a hold-down button sequence to try to backdoor your way into the set to see if the panel will light. You may have simply racked up too many "weird tuner faults" and need to reset it. My suspicion is that it's either that or bad panel backlight.

Unplug set, press and hold (on set) volume-down and channel-down and hold them while pluging in set. Will come on with "k" on screen, or will crash again if backlight bad. If it stays on, use your remote and arrow right then look for "fact init" and any other reset and turn them on. Arrow back up to "fact init" and hit enter. Let set recycle to green and unplug/re-plug in 5 seconds: the set should be in OOB state

VS 5001R sounds like its gonna turn on but doesnt


This chassis model line had issues with the vertical output IC shorting causing shut down.
It also had issues with intermittent solder connections in the Horizontal Circuit. I would not try to fix it your self unless you are very familiar with Projection circuitry and electronics background.
Hope this helps,

Tv shuts off automatically periodically


There is a switch located behind the lamp vent panel on the back of the set. Remove the vent panel and hold this switch in the down position while you turn the set on. The set should stay on as long as this switch is in the down position. If the set stays on, check the inside of the cover you just removed from the set. Locate where the switch rests against it and make sure that it is not broken. When you reinstall the vent cover, lay it flat against the back of the set and slide it down so it can catch the switch on the way down. Most times this switch will come loose and flip up while moving the set. Or if you just replaced a lamp and didn't get the switch back in the right position.

My Sharp LCD 26" TV shows most black and shadow colours as vivid blue, I have tried resetting the colour to factory reset but that didn't seem to help at all. It occurs on all channels and on 3...


the problem with LCD tvs are that they have back lamps that shine thru the LCD sceen. the job of the screen is to block the light of the different colors to make the picture. the problem is that the very thin screen can not block all the light. if the set has a back lamp setting turn down the back lamps and adjust the brightness control it should help a little. you my notice that the blacks and dark sceens look better when the room is fully lit and look much worse in a darken room.
