I have a LCD32W60D Hisense Television. The AV channel is now flashing 'no signal' so cannot get my dstv channels anymore - it has been fine for the last year. When I switched on today it was fine but when I chose TV thru source and then went back to AV it was flashing 'no signal' again and the sound is there but breaks with every flash

This is likely to be caused by the changing of the screen mode between ads and or programs, by your TV.

If so, changing the Sky output to 16:9 will fix it.

Press [Services]

Select option 4 - System Setup

Select option 1 - Picture Settings

Change "Location 1" TV setting to 16:9 (This will make the Sky box handle any changes and give you a permanent widescreen output to your TV. This is the recommended setting for widescreen TVs, but sadly, few Sky installers bother to do it.

You can also change "Location 2" if you have a second widescreen TV connected in another room.

Whilst in this menu change the Video Output to RGB from PAL (If not set already) RGB gives a much more stable picture (particularly on the menu system)

Go to Save new settings and press [Select]

Exit the menu system, and you problem should be solved.

It sounds like it's the inverter panel which lites the lcd back light.
If it's under warranty, try to replace it, or take it in for svc.

SOURCE: No picture, sound ok

I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

What I found out is target has several manufactures that make the trutech products. I have the PLV16260. I called target @ 1800-440-0680 and was transfered to the electronics dept. They told me to look on the back label of the tv and there is a manufacturer name there. Mine was made by ALCO. Their number is 888-252-6352. I just spoke to them and they said the reason the screen is blank is that it is the power supply board. They informed me that if I ship it to them in Buffalo NY that they can repair it for 135.00. I had a repair person come out and they want over 300.00 to fix it. Shipping it will be a problem for me so I am checking to see if they have a replacement board I can buy and have someone install for me.
The other interesting thing they told me was that even though it is out of warranty - if it was not repairable they would replace it with a current model. It might be worth shipping.I am waitng for them to get back to me.
Hope this helps

SOURCE: sound doesn't work on television

Sounds like there was a power surge that caused the audio processor in the TV to go out. This is fixed by replacing the main board.

The power supply board in the TV should also be checked as that could have been damaged as well. These are usually the first to go out from a power surge. Get a good surge protector to help prevent this in the future.
