I have had the same problem with my HDTV. Its a Sanyo 42" Plasma TV. Well at first it use to turn black from time to time and then it got more frequent. Well I also noticed that it did that more often during the summer when it gets warmer. Well the way i solved this was to add a fan behind my TV. Something that pushes the warm air out and lets in cooler air would help i think. I think that can work.

Polaroid TV screen will not always come on.


Are you talking monitor rather than tv? I have an LG 22 inch monitor and the on off button is on the bottom, If I don't hit it right or just tap it, it won't turn off but flashes. Where do you have it plugged in? Is it with some other electronics, or right to the wall outlet? I'm really at a loss as to what your problem really is. Are you using the remote? One quick fix might be the battery's in the remote. If they don't have enough power, short or no signal will be sent to tv or not being able to decipher it.

My Insignia TV has a blue screen with parental cotrol the problem is I don't have a Control to pres display how can I unlock it???? HELP:(


Hello
When an Insignia TV is locked, it keeps you from watching all of your channels by only displaying a black screen. Insignia TVs are locked from a single button command on the remote control, so it is easy for you to lock the TV by accident. Since Insignia TVs can be locked so easily, it's important to know how to undo this command and unlock the TV yourself. So, unlock your Insignia TV with the push of a button and once again enjoy watching your favorite programs.
· Find the lock button on the Insignia remote control. The lock button is located on the third column from the left on the second row from the top of the remote.

·Stand within operating range of the Insignia TV, then aim the remote at the TV's receiver and press the "Lock" button on the remote control.
· Aim the remote at the TV and press the channel buttons to make sure the TV is unlocked. When the TV is locked, it shows a black screen and does not allow you to view anything else. If the screen remains black, press the "Lock" button again. If this doesn't work, change the batteries in the remote and start over at step
OK
