TV keeps turning off.

The time of tv powered varies. Maybe about 15 - 25 mins. When the tv is turn on for the first time, last longer, maybe about 35-40 min, then it turns off and keeps doing it every 15-20 mins. The center light flash like two or three times. And do the same when I try to turn the tv on.

Re: TV keeps turning off.

Could be a couple of things
first i would guess to be convergance ic then IC831S (STR-X6456).and could be loose connection.
you could try this to narrow it down, purchase a can of freeze at radio shock and spray it on these ic one at a time see if it stays on longer or just replace them

Keeps turning off by itself after about 30 minutes

Is your air intake clean or clogged.. Maybe it's overheating causing it to shut off.. Had the same problem didn't replace the bulb but cleaned the intake and it works great again. Worth a try.. Intake is located on the left back pannel of the tv.. outside pannel pops off easly.

TV keeps changing channels

Out of 30 years in the repair field, I have seen this problem maybe 4 times. Once was a stuck button on the keypad of the tv. The other time was a second remote control with a book sitting on it and it would turn the tv on and off when someone would move something on the coffee table, another time was a bad solder connections on the microprocessor on the keypad circuit board and the last time was from a humorous neighbor in an apartment complex who thought he was funny who had an all in one remote control programmed for his neighbor's tv set.

Projection TV turns off for a few seconds

Good Day, boattech1;
To my understanding the Model 53UDX10B is a rear projection, that uses no fans. I think maybe your LAMP may be getting weak.
Good Luck, big IRISH.

Akai PT5598HDX/SMS won't turn on

Just a thaught, I could be wrong, maybe a problem with the power button on the remote ? It might shut the TV off, and when you do keep pressing the remote button, the red light on the TV will keep flashing like that also. Ive seen this prob on a few other blogs, so seems to be pretty common. I know I like to keep the remote pointed at the TV all the time, maybe try pointing it away for a while, just to see.
