Re: tv shut off and wont come back on

Your TV is going into some kind of a protection shutdown. In todays tvs just about anything wrong anywhere and the tv will do what it is doing. Unfortunatley there is probably little you can do yourself to track it down, probably need a pro.

My panasonic pt50lcx64 will not stay on, sometimes wont even turn on, but when it does, it lasts about 5 min then cuts off and the yellow light blinks 2x every 5 sec

Try typing your model tv along with the words "trouble codes" This could be a code 22 or a 2. Sounds like a bad connection or bad component failing such as capacitor or resistor. The tv may be shutting down as protection against what it senses as a power supply failure.

Had a power outage while watching tv. Then 3 blinking lights.

This is an on-going problem with DLP sets. Normally you shut the set off and the cooling fan cools the lamp down and then it shuts off. In your case, of which it's not your fault, however your lamp has taken a major hit by not properly cooling down, in turn, you need to replace your lamp at this time.
I suggest in the future if you have an electrical storm and a chance of a power outage while your watching tv, I would'nt play that model or any other model of a DLP set.

Hi i need your help please

When you adjsuted for the blue you were actually adjusting the voltages to the CRTs (lamps) which in turn shut them down. You will need to turn each one of the dials up agin untill your tubes stay lit, then the coolant in the green and blue CRTs will need to be changed as the green evidently is contaminated thereby making the blue dominant. But when you turn down the G2 controls your actually turning down the High voltage to the picture tubes thats why they dropped out on you.

Error Code 5 flashes when unit shuts down

Good Day;
It sounds like the TV may have a shorted CRT, picture tube, but let's trouble shoot:
1. Unplug TV from wall.
2. Remove speaker grill, two on bottom, the screws are covered with plastic caps, right and left side on bottom next to floor.
3. Remove inner panel.
4. The blue tube is the one the right side, remove socket, with phillips driver, make sure it's not touching anything.
5. Plug and turn TV back on, if picture appears with no blue it's the tube.
6. If still shuts down, bad blue CRT driver IC.
CAUTION: Call a factory authorized service dealer to give you an estimate, if this sounds too hard.
Good Luck, Day, Big Irish.

It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

Covergence problem

your set has indications of several problems. red green and blue. indcate convegence issue. the fact that the picture is concave is a indication of totall loss of covergence power supply. the convegence menu missing idicate loss of some voltages from what know as the flyback.AND SHUTDOWN. indicate further problems. generally when convergence fails ..not always the set wont shut down. it could be a simple issue but further trobleshooting would have to occur to narrow it down.

Open up the front and check for fluid under the CRT circuit boards. The one on the right (as you face your TV) is the blue one. For some reason, the diaphram for the glycerin in the blue optic is on the back side and leans down. It tends to leak and spill on to the circuit board below.
Tell tale sign is the pool of fluid when you access the front chassis. Pull off the speaker grill and shine a flashlight on the inside underneath the CRT circuit boards and look for the fluid. Glycerin doesn't dry. TV is powering off most likely to protect itself from the shorts.

Tv keeps turning off?

cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 12 - No Error detected, check Power Supply 32 - Lamp Cover is open 33 - Air Filter Cover is open 34 - Lamp abnormality 36 - Light Engine (DMD or LAMP Fan stopped) 37 - Exhaust or Lamp Ballast Fan stopped 38 - Lamp temperature high 39 - DMD temperature high 41 - Short is detected 44 - DVI cable between FMT & Engine disconnected. Sorry for the long answer but it was an open ended question.
