Question about LG RU-44SZ63D Television

1 Answer

Temperature too hot warning

I have an LG RU44SZ63D DLP TV. A few weeks ago I started getting a TEMPERATURE IS TOO HOT message displayed on my TV. I removed and replaced the bulb, cleaned all of the visible vents, and reset the bulb timer. I also moved the TV further from the wall to get better ventilation. The internal fans that I could see appear to be working. I am still getting still get the same warning message after about an hour or so of watching the TV. Do you have any other suggestions ?

Above are links for your service manual, and a training manual. This is a classic switchmode power supply, shutting down to avoid a fire, explosion, or both. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an Akai, Approved Service Center, this point is very important for a good result, Always contact, their local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free.

The power on problem is a cap in the power on circuit. The loss of signal for an areal is delayed. Nothing you can for DIY.It needs repair shop visit.

Why does My Jeep run for about 200 yards then shuts down , after about 10 min. it will start and do the same .on the inst.panel it reads hot oil


You need to scan the engine control unit for fault codes, it will have some I am sure. Check The codes by turning the ignition key to run and then off, then to run and then off, then to run and wait for the codes to be displayed in the digital mileage display.

There could be a loss of freon(unlikely but possible), the start capacitor for the compressor is bad (most likely) or the thermal cut off switch on the compressor is cycling from the hot compressor.

When I try to start the engine a hot message comes on at the temperature gage area, is this a sending unit default and it will be cleared by replacing the sending unit?


Does it continue to indicate "HOT" after it has started, or does it then go out? Does the vehicle also have a temperature gauge in addition to the over temperature warning light?

If the coolant level is at the correct level and the belt(s) are are correctly in place, it's most likely a bad sending unit.

Might try disconnecting the wire from the sending unit and see if this will cause the light to not come on.

I would suggest that you turn temperature setting up to 140 degrees and see if this won't help you. Obviously with water temperature that high make sure no little ones are left unattendded. Thank you
