It's pricey alright. If you can live with the dim bar, I'd just leave it as is. They just clip in but the LCD must come apart, very difficult.

Re: Sharp LC32D44E-BK Stuck in standby mode

How?

[Jahson]

Re: Sharp LC32D44E-BK Stuck in standby mode

Had to scan it on analog tv first, change language to sweden save settings. yea you would not pickup any stations on analog, so you can stop it as it starts to scan.
Then auto installation on DTV, sorted.

I read it somewere.

Re: Sharp LC32D44E-BK Stuck in standby mode

Yeah, I just went around to customer's place to fix the TV's freeview (sold it to them about a month ago), but they were getting no channels. A simple FACTORY INIT (from service mode) sorted it in that case... these Sharp TVs seem to have odd problems with Freeview.

Re: Sharp LC32D44E-BK Stuck in standby mode

Yea tell me about it, when i replace the bridge on C7558, the tv wont come out of servive mode like i could of before, tv was saying No Signal?.

So i had to hold down vol+ input --> & power switch. Done the trick, took it out of service mode.

Tv work perfect, im going order the ccfl lamp sunday should reach me tuesday.

So i've going have more questions for you when it comes .

Re: Sharp LC32D44E-BK Stuck in standby mode

One thing to be concerned about is if the problem is not a failed bulb, you should check it by taking the panel apart first.

Re: Sharp LC32D44E-BK Stuck in standby mode

Yea i when back into service mode and check the lamp error it had
1b lamperror 00h 00m
1b lamperror 00h 00m
1b lamperror 00h 00m
1b lamperror 00h 00m
1b lamperror 00h 00m

Yea suppose you got a point about taking panel off. i try enjoy it for 24 hours first.

Re: Sharp LC32D44E-BK Stuck in standby mode

Lamp error can occur due to bad inverter connections and dirty screws too.

Re: Sharp LC32D44E-BK Stuck in standby mode

Ok didnt know that, but i can see that dimmish looking line going across the screen coz i know its there, but if not looking dont thing you notice it, maybe if a white screen was showing only.

yea i still check tho.

[tom66]

Re: Sharp LC32D44E-BK Stuck in standby mode

Ah yeah so the bulb is dead then, although it is possible it is just dirty or loose connection.

[Jahson]

Re: Sharp LC32D44E-BK Stuck in standby mode

Changed the ccfl & changed the wrong one
aint there a way to see all the ccfl on, to see the correct one to change.

[tom66]

Re: Sharp LC32D44E-BK Stuck in standby mode

Yes... You can go into the service menu and select a test pattern. One of them is full white.

[Jahson]

Re: Sharp LC32D44E-BK Stuck in standby mode

Its ok, i selected the correct ccfl this time, the dim line has gone, removed bridge on C7558, just the channels scrambled again. Many Many Thanx Tom66, This one has been fixed.

Hiya
I'm Dan, self employed electronics tech from North Derbyshire. Do mostly TV's and Guitar amps. This is my first post.

I have one of these too, an LC32D44E. I have managed to keep it on by bridging C7558 0.47uF SMD cap. I also cleared the lamp error count on page 10/11 in the service mode. I looked at the screen on white screen and there are no dark bands but I did notice that when the TV has been off for a while and started from cold, the ccfl lamps come on very pink and gradually turn white. Could anyone tell me if this is a lamp or inverter fault. The TV has been well used, I wondered if all the lamps are passed their sell by date as it is a very uniform pink or whether the supply to the inverters is low.

Dan.

Re: Sharp LC32D44E-BK Stuck in standby mode

Hope can be of help. Had couple of spare days last xmas, Repaired 3 of your model tv. All 3 turned out to be faulty panel only. One of them came on exactly as yours, pink to start, then white. Had spare psu and main boards, didn't need them.Also had spare tv I bought for 50 pounds. That came in usefull, had cracked screen, hence the price. Before you start spending money, check connetions etc. in the panel. The one with fault like yours was well used and dirty inside the panel. One tip, I ran chassis upside down with lamps exposed until I had nailed it. All 3 are now running, no backlight problems. Dan, I hope this is of some help.

Re: Sharp LC32D44E-BK Stuck in standby mode

The bulbs on these TVs normally run pink on start. They are very low mercury bulbs, due to environmental restrictions, but as such, have a shorter life. If the TV isn't flickering and there are no dim bars, I would leave it as is.
