Question about Sharp Projection Televisions

2 Answers

We have a Sharp's Aquos LCD 48in Colour television. The problem we have is when we sit down to watch the televisioncould be a few minutes or a couple of hours, then all of a sudden it turns pink after a while a black screen appears and in the corner of the screen,there is a black and white squares which takes up a third of the screen. The sound is still there, we switch it off and everything is back to normal and then it reapeats it self.

Possibly firmware issue and Sharp service center can fix it with special firmware update tools.

Sounds like one of the components in the power supply section is over heating

    you would need to dissasemble it and use a can of compressed air to blow air on various components when it fails again to locate the problem... also examine the capacitors by sight and by feel.... if they have bulged on the top they have failed.... i'm currently repairing an lcd monitor because of capacitor failure

Damaged the LCD - Sharp 46 in. LCD Full HD Television, AQUOS®


Yes it is possible to replace the panel. I would suspect that it is cost prohibitive however. I am willing to state that the cost of the panel will be close to if not more than the cost to replace the TV.

Sorry about the bad news.

SHARP AQUOS LC-26P70E - Clock


Most TV's don't change with daylight savings time, since they do not operate with a date, just time. You will need to change it via the remote.
Good luck

Sharp Aquos power up delay


Have you checked the voltage in your home?
How about the way your outlets are wired?
Do you have too few outlets and many other things on the same circuit?
Sometimes you can have a continual problem with it like a brown out.
My daughter and her husband were living in an apartment that had only one good electric circuit and another iffy one, needless to say, they moved to another better apartment.
Brownouts were occuring all the time, because of insufficient current when so many things are on one circuit.
You may have a situation that has caused a power surge and caused the same problem with both tv's.
The best protection is a GFCI outlet installed where the tv is AND a power strip that protects against lighning.
Let me know what you see.

This will be horrible news, the screens are fragile and what happened is you broke the screen, And since this falls under customer abuse it will not be covered by warranty, so the cost of replacing that screen will run anywhere from $1200.00 to 1600.00

Sony KP-51HW40 51 in. Rear Projection turns blue


Hello......
First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.
