The entire screen is green but the audio is fine.......the tv is about 2 years old....any suggestions?

Try to turn the TV off and on by removing the power plug. Leave the plug out for at least one hour and then try again.

i would suggest a different refresh rate. should be in display properties.

I have the same problem with a 40" Toshiba LCD, Component cables work fine with FIOS but not HMDI, goes in and out then blank. HDMI with DVD player works fine. Best buy reported this same problem from users with this toshiba lcd but no solution.

I have the same TV and the same problem and it's also just over 2 years old (bought it June 2006) when the problem started. Every day, I saw the blue streak cover more of the tv, now 6 months later, it has all turned to green and the entire tv has a green tint. It looks like I am watching tv in murky green water.
I am lucky that I purchased the additional warranty on the tv and finally got around to calling them. I hate to tell you this, but they told me that the optical light has gone up and they are replacing the tv.

I would suggest getting another optical block from the repair man. Apparently even some replacement blocks have had issues...

if you have warranty work they will direct you to the service center you will need, I do not know of any bb that service tv's.

Have a problem with Zenith 37 HDTV. Medel number: Z37LZ5D As wathcing TV, along with 'pop' sound, TV went dead. LG service center gave an advice to unplug the power cord and press ON/OFF power switch about 1 min. Then plug power back and turn on the TV. Well, the green light blink for a while and solid green, but still no screen, no audio. Search the Web and someone suggested to replace Power Supply Board which will fix the problem. Again, search the Web and came out with Power Supply Board. LG Electronics/Zenith 'Power Supply Assembl' with $124.95 from PartStore.com. Is it the right solution? Do I have to replace entire Assembly Board? not just replacing some fuse? Any cheaper way to do? If I have to replce PSA board, any suggestion to how? Comment posted on Apr 22, 2009 I have a basic knowledge of electric and electronics, such as rewiring entire house for renovation and assemble entire computer from scratch.
Actually, the TV belongs to my father and the problem that I stated was based on what he told me.
So the question is based on the symptom that I posted, how sure are you that the problem is the Power Supply Board?
Is it good to order PSB? Comment posted on Apr 23, 2009 Purchased 2 and half years ago. Expired one year warranty. Comment posted on Apr 23, 2009 Zohail,
This is LCD TV.
There is no problem with the wall socket nor current.
I put other appliances on same wall socket and worked.
It has to be internal problem.
As I mentioned on the main post, there was a 'pop' sound while watching and TV went dead.
Turn on remote control, there is blink green light and then green stays on, but no sound, no screen.
Turn off remote control, light turns red. Comment posted on May 14, 2009 I fixed the TV.
Orderd power supply board which cost me $136.51 total.
Replacing was simple.
Just removed the rear panel cover then electronic board housing cover.
Took power supply board with all the connector cables and replaced with new one.
Problem was a transformer connector which got burned and blow up the plastic cover.
But no problem with fuse and capacitors.

Thanks all for advises.

1.Check audio/video RCA jack cables
2.check S-video(if you use S-video cables)
3.check with another dvd player to get normal picture on your tv system. if picture is normal in this process. then problem with your old dvd player.
4.if same problem occurs in other dvd player. then problem with your television. external audio/video processing circuits
5.if the tv is ok. then the problem with your old Dvd player audio.video converting circuits
6. if can be rectified by authorised service engineers
7.Contact service engineer. as there is no recitification process from user part

I just called Vizio and they said to unplug the TV, then physically hold in the power button on the TV for 2 minutes.
