1. After being on for 1-2 hours the pic goes out and turns to "the green screen of death". Pic will not come back on unless TV cools for 30+ min. 2. When I switch from DVD source to cable TV source the pic...


You got an issue with overheating.  TV is designed to shut off to protect electronic components if TV overheats.  Take it to the shop and have them open this thing up to identify the faulty circuit.  Also, check to make sure your not blocking the heat vents.

Hitachi 42EDT41A Plasma (Snow, very light pic), all else OK


LCDs are worth it to have as to a Plasma set as plasma tvs do need time to warm up LCD and LED tvs dont have that warm up time to wait for things to smooth out however if you wish to have the tv serviced it is fully up to the owner of that TV now mind you there is also OLED tvs out there in the market as well and with the cost of LCD tvs going down to about 500 bucks you might be more interested in that but thats my IMO on buying a TV set

My Sony T.V 2000 model# KV-32XBR400 Is a great T.V we love the size and Pic. the problem is when you turn on the T.V it goes to standby mode and no pic will come on. If you move or shake the large T.V....


There are bad solder connections inside that should easily repaired. If you can solder, you can fix this yourself. Look for solder joints that appear grainy or have rings and resolder them.

Keep us posted.
