how do i get rid of shadowing on my scrreen

I just fixed one with the same problem. The light flashed 13 times.
I had to cut one trace on the hv board to one of the lamp drivers.
There is a slight but barely noticeable darken line across the screen but the tv stays on now and the picture is good. I don't
know if the lamps can be replaced but why bother now.

U have a Digital Camera turn it on,take ur tv remote pushes all the remote buttons on the front of the Digital Camera.One by one buttons.If all buttons of the tv remote work will register on the Camera viewing screen,because the Digital Camera able to read infer red signal output.Will figure out wright away the tv remote work or not easily.Tv remote sensor/board have no LED power light lite up might just be a lose connection or just a dead LED lamp only,because all the buttons on the remote sensor/board to the tv panel work wright?Try website Remotes.com to buy tv original remote.

If you have a DVR box or a cable modem of some sort, try rebooting it. Just turn it off for 20 seconds and then turn it back on. It takes a while to reset, but I have used this method to solve many problems with my tv and computers.

It is a power supply problem, if you change out the power supply ro replace the bad electrolytic caps on the power supply that should fix your problem, or got to www.partstore.com

The image on the screen is generated this way in your tv: the tuner receives the channel and extracts the signal out of it; the image processor from the mainboard uses the signal to generate the data for the image: the T-con board gets this data and generate the commands for the pixels from the LCD panel accordingly.
In your case either the connection between the T-Con board responsible for that part of the screen is loose, just refit it - or the board itself is failing.
This is a replacement board

most plasma tv have two power botton, ha main power which is mostly located at the lower side of the tv, and the sub power/standby power botton located in the top of the tv.. check if there is red, orange and green light on power led indecator. other wise there is problem with you power supply.... you may call qualified technician.

Go into the tv menu go into the AUDIO setting,go down to do a resetting for a back to the factory setting.Now go to OPTION setting go down Output Select and enter and pick Fixed for speakers for the tv option,now tv will play on the tv speakers

I am sorry to say, but it sounds like your panel is faulty and needs replaced. If not under warranty, it will be cheaper to buy a new set.

make sure before u do that apply or click accept.or save.thanks

8 flash is Audio Protection. You need to have the AU board replaced. PN: A-1433-191-A. I hope this was of some assistance.

Hi there. I found a guy online with the exact same problem. It could be that the Balancer / Inverter board is bad or a bad CCFL tube.

Possible that the TV has a short or faulty circuit in the main board. So it is important to have a check on the main drivers of the mother board , look for faulty drivers, faulty electrolytic capacitors that are short or faulty semiconductors

You must disconnect the SMPS and then check with the main circuit using a multimeter looking for the power circuit. Check if there is possibility of dry soldering- a tap on the board can confirm.

check power supply if theres an output.try to check your inverter board if theres input supply.

when it turn on just blinking few times and then goes off

please let sony know as i have the same probem and they are not acknowledging the problem with this model
