This is due to dust buildup in light engine. you can replace it simply enough, comes out of the back. have to remove a couple of wire harnesses and a dvi cable that plugs into digital board on the left side. it's too complicated to repair for the novice.

Yellow patch error


Not too sure what you mean about a yellow patch error.
Does this 'Yellow patch" have a splurge effect or is it more regular?
The only thing I can suggest is try several purges of the head.
The other possibility is, some torn media stuck deep inside the print unit further investigation would be necessary.
Good Luck.

Yellowing on Hitachi 65T500 screen


Go to main menu, turn color all the way off to see if you have perfect black and white. If you still have yellow, it's in the focus block or convergence circuit, If it's perfect black and white then it's going to be in yc chroma luminence circuit.

I have a giant yellow patch that looks like a fingerprint taking up most of the centre of the secreen (around 2/3). Can this be caused by an earthquake / shaking the TV or is it caused by something else?


If your TV looks 3D, warped, or distorted it likely has a convergenge problem. If however it just looks dull, washed out, redish, or if it looks like objects on the screen have halos the fluid in the lens has soured. You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

My samsung blackjack has differnt colors on its screen


yes ..it is cracked..the screen must be replaced...and you don't have to drop the phones for this to happen....leaving it in the sunlight and exposed to cold and hot temperatures causes the screen to contract and expand...which eventually cracks them from the stresses...so...not your fault...no worries..but yes for sure...the screen must be replaced or get a new phone.....

Check the proximity of magnetic fields. Large Speakers near the TV for example will cause colour distortion.

Screen patch


Sometimes lcds will turn a yellow/brown/redish colour if they overheat. normally this will not cause long term damage to the screen but it is not good for it, try letting the monitor cool then using commpressed air to get rid of dust or attach a small fan to see if it helps. This may not fix the problem but should confirm if thats what it is.
