Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

audio and video work on two different circuits in the tv. that is why you can get audio with out video and the other way around or sometimes when you watch the tv the speech is not in synch with the mouth movements
To make the decision to repair or junk take it to a tv repair shop and get a quote first and compare that to the price of a new item

have you tried pressing mute botton or turning volume up ? also is all leads in properly as they can come loose and stop sounds sometimes ( happens a lot on scart leads )

This is a very common failure on Projection sets. Its called a convergence problem.

You may have one or more of the following symptoms.

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• No Audio / No Video - Makes Chirping Sounds

You can see some examples and find a fix here...

If it's a big tv it can just take a little while to power up, I've found that pushing channel up button switches on tv quicker but I've no idea why.

Unless you want to save power you should only be switching tv to standby, there will still be a light on the tv somewhere, blue or red it varies. TV's turn on much faster from standby than completely off.

First, You cannot resync the remote, Second the IR sensor may be bad on the tv and third, the Digital bd may be bad. The IR sensor connects directly to the Digital bd which is the brains of the tv. Also, there maybe a stuck button on the remote or the buttons on the tv.

tv has power but does not have picture or sound. it is a 37 in akia

Hi,

If you keep the TV disconnected from the power long enough, the TV should hard reset.

its the power pack in the tv that has gone out...contact the manufacturer for either the part to replace it your self or for a technician to repair it.

Please, give us a better description of exactly what you see on the screen.
