Question about Televison & Video

1 Answer

My lg 42PQ3000 has a problem. The picture just dissapeared this afternoon but the sound continued. The remote control doesn't work except for the power button and when I try the buttons on the actual tv itself it just tells me that keylock is on and I can't do anything with it.the screen is now a bright grey instead of the black screen that was there earlier but the situation is still the same. i have now plugged an auxillary digital set top box into the tv which automatically turns the tv to av channel and this now works but the tv functions still do not. even though the tv works through the auxillary digi-box there are two signals at the top of the screen saying xd on over the top left and xd off over the top right and the screen tone is different on the left side to the right with a clear split line down the centre of the screen. please help!!!

Try unplugging the power and then holding down the power button for a few seconds either on the remote or tv. I think this will reset the lcd tv. Tell me if this works.

My LG 42PQ3000 is making a clicking noise from the large PCB when power is turned on, there is no picture and the stand by light is going on and off


Standby light goin On/Off, means the power supply regulator board is OK. Blinking of the standby light indicates a fault. It might be to the backlight inverter board, or the main board. These blinks of standby light are called blinking codes, from the number of blinks occur at one time switch ON, you can get an idea about the faulty board inside the TV. Count this blinks. If you wish to get more details about these blinking codes, check the site linked here.http://electronicshelponline.blogspot.com/
Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

The picture on my lg tv has gone dark. Every button on the remote is working except the menu button.The button on the side for menu is not working either.


Check and repair the remote control. It sounds that it need cleaning. But lack of brightness to a Plasma screen might be to a faulty Z Sustain board. Check this for more details about the TV fualts, and to how to repair and clean a remote control.

RX-V465 Yamaha Reciver we can get picture but no sound w/PS3


Check HDMI Sound settings:
Enter Setup menu via remote, then Func. Setup / HDMI / Audio. You can choose from Amp (sound will be played via Yamaha), TV (sound will go straight via HDMI out to your TV and not play on Yamaha) and Amp+TV (Yamaha will play the sound and also pass it to the TV).
Also what is your source? DVD or some network player? For example Yamaha cannot decode audio in AAC or other computer formats, so be sure to change the audio settings of your player to output PCM and not raw/bitstream.

Go to the manufacturer of the remote's web site. In the support and service area there should be a search bar. Key in 'manufacturer tv codes' it will be there.

Set turns itself on and off with no picture nor sound


You have a major problem with this set. Could be the main board, the Y-SUS board, or the power board or some combination of these.

Picture is frozen but the sound is working.


Hi,

I'll think that your TV has the child-lock (parental control) switch on.
You can change that in the menu.
I'll hope this works out for you.

Kind regards,
Gerard
