No picture. Have power and signal - Orion Computers & Internet

power board

I have three of these TVs in the shop. They are less than a year old. The signal board is good, the T-con board is good, and the power supply is good. The panel (once called picture tube) is bad. Much too costly for repair. Thanks for asking me.

A blue screen usually is present if no signal is connected to the set---hook a DVD up to one of the rear inputs--select that input and see if have picture and sound.

If that works connect cable or antenna to set and select that input

NO signal is like no gas in car---it will not run.

Tries pushes the power switch on the remote few times,each times push wait like a 1 mins or 2 mins for the tv Tuner signal board to take it effect.This process should get ur tv picture back,because the tv Tuner signal board it is old and having problems,evenually require replacement of a refurbish tv Tuner signal board.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.

Try replacing the main board

One problem with digital television is that the carrier frequency of the channels was shifted to a higher frequency vs the old standard . These allotted frequencies require a whole lot more output power at the stations as well as they follow a straight line and the bounce (reflect) off of natural objects such as tree leaves, rain drops moisture, power towers etc. In other words unless you live right next to the transmission tower, you get a lousy picture. Since it is a digital signal, and your receiver does not collect more than a significant portion of the transmission signal, it cannot render the picture so, drop outs causes loss of signal and no picture at times.

That is why most people go to cable or satellite to get a continuous signal.

I would say that unless you put up a good active antennae, you will not get a decent picture. Even then you will not be satisfied. The stations will have to do a lot more work on their signals and up there power levels to compete with cable, but hey, they don't care about their over the air signal since they can sell their signal to the cable operators for lots of bucks and reach more eyes for their advertisers.

hi! maybe there is a problem on power supply section or loose connection.

Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:

* Off entirely.
* Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode.
* Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer
* On fully, receiving an image, and displaying.

Hope this helps.

Hi,

I have this Panasonic PanaSync SL70 17'' monitor, I don't use it often. It is still in very great shape. However, I tried to turn it on yesterday, I got a black screen. The power LED is on and I can hear the relay is clicking when signal received. I tried to remove the signal cable, I can see it turns to power saving mode. It seems that everything works fine except no picture. I am if the transformer is gone, but not sure. I am wondering if you can help?
