When the unit start up its fine within 1 minute vertical lines show

1. Unplug unit from wall for 3 minutes;
2. Press & hold Power button for 1 minute;
3. Plug in unit.
OR:
1. Unplug for 3 minutes.
2. Plug in unit.
3. HOLD Power Button as unit starts ... hold until the unit flickers on then off twice.


This effectively returns the components to factory specs, much like resetting a computer. It offers a *temporary* fix, lasting 45 minutes to hours. All depends on the unit.

Mom has an Insignia 32" with the same color separation problem, which worsens as the day progresses. Best results achieved while television is cold.

Dust in the unit could contribute to the problem ... try to keep the unit dust free as possible.

Hi,
Your vetical ouput deflection is gone that's why it will not power up. This is commonly caused of shorted vertical output IC. This is not DIY because the FF is still to be consider :
1. Fusible resistor in line with the supply of vertical output IC.
2. Yoke winding might be open.
3. No vertical output from the jungle IC.
I've advice you to send it to the nearest Sony service center in your area.
Hope it may help you.
Have a nice day.

is it under warranty? if it is get a new one. if not you can open it andclean it out as good as you can. its getting hot on the video chip and thats why.

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

yes and no. That particular tv you have is done for, but if you just purchased it 6 months ago, you are still within you 1 year warranty with sharp. they will ask you to take it to a authorized service center and you need to follow through with the process. about a week or 2 will pass and the service center will deem the unit unrepairable and sharp will replace it if they cant solve the problem. give em call..good luck 2u

Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan

I assumed you are using a digital copier/printer, in digital machine there were 2 kinds of diagnosing a problem, and you are right with your observation Copying and Printing, and each have two separate troubleshooting.

If you say that in printing is fine, then the problem is with the scanning part which is in your Optical Unit, here's some pointers

1- Open the optical glass on the top, with screws

2- Observed the optical unit with 3 reflective glass, it could be dirty
3- the middle of the optical system is called the CCD which converts the image from the reflective mirrors, see if you can find dust and dirt.
4- Check the lamp for any sign of dirt this could cause also some problems.

these are the only areas you need to check, nothing else, and this would surely solve this problem

I had a smililar problem after taking it apart i realised that i had screwed my mount skrews into the video main board and cracked it along with a few soldered wires, if you havent done any physical dammage to it try a firmware upgrade

if the tv is less than a year old , call 1-800-SAMSUNG for warranty repair, the lcd panel is bad

I have not fixed it yet. But I have identified the chip that is causing the problem. If you have a service manual scan it and post it please, so I can show you the chip.
