Hitatchi Ultravision LCD Widescreen acts like it doesn't want to power up

I have a Hitachi Ultravision LCD Widescreen. This morning I had sound but a white screen with two blue lines at the top and the power light turned blue and the temp light and the lamp lights started blinking. Later the tv worked fined. This evening it acts like it don't want to power up. No picture no sound can change input, it's like the tv is dead. Same blinking lights and when I turn off the tv the lamp light stays red. Help! Give me some advice so when I do have it serviced and it comes back I'll know they did the right thing.

Hey, I found this on a blogsite about lcd rear projections....looks like our tv's screens have been burned by the "pillers" that surround the tv when switching from 4:3 to 16:9 or fullscreen... read below, I hope it helps !

Rear projection crt's,the first generation widescreen tv's were notorious for that.Lcd and plasma can have the same problem,but it takes much longer and is not as harsh.Dlp's use tiny mirrors,so it isn't a problem with them.Lcd and plasma tv's should be ok unless you watch them with blck bars on them all the time.
We have lcd monitors at work,and i've seen them after a year with bad burn in.They also run 24 hrs a day 7 days a week with the same display.

GKar posted 2006 Oct 10 15:31 TooLFooL : i have 51" sony rear-projection and those freakin' grey bars burned themselves right into the screen...

I read that to avoid the burning you had to limit your 4:3 viewing time to 15% of total time viewed. (applied to my TV but apparently yours and others as well...great! now they tell you :-x , this applies unless 4:3 aspect was changed to stretched or zoomed...yuck :-x )

This really sucks as a Star Trek/Lexx/Farscape fan as they are mostly 4:3, fortunately the upconvert player/hdmi combo sends a 1080i 16:9 signal to my TV so the effects are drastically reduced by nearly filling the TV without the grey bars or burn in problem without stretch or zoom modes being used. yay! :wink: (default grey bars set to black automatically, apparently grey isn't needed due to screen area covered is sufficient for burn in not to be a problem.)

Both of these problems sound like the 2 convergence ic's. Not something the owner is really able to repair. You'll need to call a svc co.

Hitatchi Ultravision rear projection **NO POWER ***

Usually, when there is no sound, it is because something is not set right in the menu. The fact that the set has shut off completely is quite common in that set. There is a little blue capacitor next to the horizontal output transistor that burns up and blows the small main B+ fuse. Those parts should be replaced by a qualified tech experienced in the Hitachi projection sets who will also check the settings in the menu to get the sound back.
