When i on the tv by remote the red standby light turns into green and i hear the tv sound but not picture and after a one or two second the green light turns into red. The tv goes into standby mode when i again on the tv by remote the red light starts blinking but i am not able to on the tv.

Have you tried a factory reset? I had a similar problem my TV was stuck on standby (red light only) I did this

1. Turn on the TV.
2. Wait approximately 40 seconds for the TV to completely start up.
3. On the TV remote control, press and hold the UP ARROW button

and it worked!

ok sir you have defective power supply at hot side section! and the power oscillstion circuit! your unit need to diagnos to know the exact defective parts!

hi this fault could be down to capacitor in the power supply, they bulge or go leaky, you need to take the back off the tv, to have a look. try and find a tv tech in your area hope it helps

Same issue with - Panasonic TH-50PX70A , power UP with red standby, then power ON by remote - only Gives GREEN led blinking 35-40 times, followed by solid green led with no no picture no sound.
>> Solution; unplug Plasma from AC 10-15min, then plug in & power on to Red standby led,, At this point - Power ON tv while holding down both -Volume Down and F (function Select) buttons (front panel door) at the same time turns picture ON,all ok.

Switch the TV on: Press the power switch A on the front of the TV. A green indicator on the front of the TV lights up when the screen is on. If the indicator is red, press the
-CH + keys on the remote control.
The green light blinks every time you press a key n the remote control.

Power board is bad.. I had the same issue.

when i turn on my tv the light turns orange green for a few seconds.

Unplug the TV for maybe 10 minutes, then turn it on. Sometimes these units simply need to recycle. If that doesn't work, you've likely got serious problems.

projection bulb needs replacement

set is going into shutdown. what type of tv is this. lcd.. could be one of many problems.
