LCD sets sometimes will not power up until the backlight boards power up. the backlight boards have SMT fuses that open. and driver FETs (commonly also SMT) that short.
check the backlight circuits first.

Sony tv screen turns green

Use the remote control to go into your TV picture settings menu and change the mode to NATURAL. It's also a good idea to check that all of your cables are in good shaped and tightly connected.

The green color could signify that your TV is magnetized. This can cause colors to draw out to the corners of the screen. Remove any magnetizing devices, like speakers, away from the TV and see if that helps.

For more solutions, read the troubleshooting steps outlined in TV color problems. I hope this helps!

The antenna plug on the back of my tv to hook cable up to just fell out. i don't know if i should be able to put it back in a specific way or if i'm just ******.

If this was the plug- the RF plug socket - that had come off and fallen all you need is to remove the power of the TV in the first place.
Now get access to the back of the TV- use a good flash light and since it is easy to see the RF pin protrudingg forward , you can plug and mate the socket into the pin.
Now if this pin is broken it can be due to a faulty pin or even if this is direct link to the TUNER in which case you will need a soldering iron to solder the broken pin and fix.
This is not a tough job and can be done by you with such care.

High Pitch Sound when TV is turned on.

problem with capacitors in a power supply. if you 're a pro, poke she set open, by taking away 3 screws at the bottomof plastic grill, right above in/out plugs. slide grill down, make sure take screws completely out. another big screw in a miggle of grill must go out. after you manage to get plastic out, you'll get metal shieild off, by taking another 3 scews at the bottom. pry it open and lift it up, then slide it out of the assembly(looks like a rectangular box. then, expose the electronics: power supply is at the top of the module, trace power cord to that. disconnect power from the unit and look for bloated elecrolytic capacitors.found the ones, replace with exact value.
good luck.

First tv kept tuning on in middle of night now its kepts tuning off while ur watching

I don't know what might have been making it turn on in the middle of the night. It it keeps turning off while you are watching, you might want to check if:
1) someone is accidentially hitting the SLEEP button on the remote. The TV will turn off automatically 30, 60 or 90 minutes after the sleep button is hit. It can also get hit if you set the remote between seat cushions on the couch and someone moves, etc.

2) Does the TV get enough ventilation to allow heat in the TV to circulate away from the set? Drapes, tight cabinet, etc. The temperature sensor may turn the TV off automatically to protect the TV.

3) Your power cord is not well plugged into the wall or you might have some issues with the wall outlet - expecially if it is an older home (before 1980). Any wiggle of the cord may cause it to disconnect for a very short time - the TV will shut off.

4) This Brand is only available through BEST BUY and this model has a 1-year warrentee. The manual says to call 1-888-BESTBUY for service.

Good luck.

Sharp LCD tv "Audio window" keeps popping up on the corner

Replacing the cable box may fix the problem. But, you're the 4th person to have this same problem with this SHARP TV MONO only audio.
Try system reset button on the back of the TV or the box.

My element 19 inch flx-1910 tv will not power up

Element FLX-1910
Problem: When the TV is turned on a picture appears for a few seconds and then the picture turns off. Audio is still heard.

Solution: Not a simple fix! This TV has 4 small florescent looking bulbs that act like a back light to light the image on the liquid crystal display (LCD). At least one of these bulbs is burned out or broken. The wires powering the broken bulb need to be cut and spiced together. Basically you’re bypassing the bulb and completing the circuit when cutting the wires going to the bulb on each end and splicing them together.

WARNING: This worked for me but no guarantee for anyone who tries it. This is a very involved procedure and involves completely dismantling your television. To be honest I don’t recommend anyone trying to fix it unless you are very technically minded and have a couple of hours to waste carefully tearing apart your TV. If anyone is willing to attempt this repair I am willing answer questions.

Cause of problem: It is my guess that this problem occurs when the TV is left on for extended periods of time. Like leaving the TV on when you fall asleep at night. My TV was left on a lot. I noticed that the plastic was melted and discolored where the bulb had burned out. (This can only be seen internally and is no way visible from the exterior)

What LCD to buy now?

Stay away from combination units, DVD's, VCR's were not meant to operate inside the cabinet of a Tv (much too hot) and if anything goes wrong with the Dvd the whole Tv (generally speaking) has to come apart..
Don't buy from sources such as Kmart, Walmart, Costco and such - and understand that almost every manufacturer out there makes a good model and makes a throw-away model. The difference you can see is generally the price. Inside it has to do with the way it was put together and the quality or inferior parts that were used...
Consumer reports is a good resource for researching the Tv you want. First find the model you would like to have then shop it for price..
Hope tis helps!
