The unit will operate fine when you turn it on then about 45 secs later it turns itself off. If I turn it on again the same thing happens, goes on for 45 secs then turns off.
The picture is fine when it is running.
Look forward to any help you can offer.
My TV was doing the same thing. Turning off after ~20-30 seconds. I replaced the bulb and had no more problems. It is made to be replaced fairly easily from a panel in the back with a phillips screwdriver. The lamp is available on-line for about $170 plus delivery (less than $200 for next day delivery). I paid a guy $100 bucks to come out and tell me that. He did give me the part number to order (which did not coincide with any markings on the bulb that was in place. For my model RU-52SZ30 it was a replacemnt bulb type 6912V00006C.
I have this kind of tv model ru-52sz30 and same problem which i fixed by replacing the bulb. there is an access door at the back of tv that you can replace the bulb. if you need more help just post reply again.

One of two things can be the problem...one the bulb is bad...two the ballast is bad. If the bulb is not bad then the ballast is...it can usually be fixed by replacing a resistor on the board itself...it is labeled R3 and is a 1000 ohm resistor
Enter in the user mode:

3.This copiers has more 12 user tools.You can see 5 user tools on the display at the same time.Use these keys to see the rest .
4.AUTO RESET: the copier return to the initial condition autommatically after your job is finished.(after 60 sec)
5.SCREEN SAVER :when the copier does not detect anyone operating it for selected time the display turns OFF.(60 sec).
6AUTO OFF:Whwn the machine is used after weekly timer has turned it OFF the copier will turn itself back OFF after the selected time.The auto OFF time can be set from 1 to 999 minute or the function can be turned.(I recomanded setting level OFF).
Check the "Sleep Timer" settings. If set to 45 minutes then TV would automatically turn itself off 45 minutes from being turned on. The variance in the "on" times is due to the TV turning itself off after not getting a signal from the remote for fifteen minutes.
I have a 52" LG Prjection TV model number RU52SZ30 and it turns off after 45 seconds, also the blinking lights flickers on the lamp. What should I do first replace the lamp or reset the tv and how can I reset my TV. If a lamp problem where can I purchase one and how much and if I buy a lamp and I still have the same problem what do I do now.
