When temps inside my house drop to around 65.f my t.v.wont turn on. The led on the front shows a steady flashing pattern. I can take my hairdryer and concentrate air on the left side(looking from the back) on the metal encased board(mounts vertical and has a led on it inside) for about 2 minutes the led on the board will start to flash then go out.,then the led on the front will go out. i then have to push the reset button,then the t.v will come on. (cold solder joint?),(normally you can hear a relay close when you push the power button,but when this occurs,nothing This t.v is 4 yrs old used daily,problem occured virtually overnight

Re: cool temps cause my t.v. to not turn on
There are six capacitors on the DM board 1000uF 16 v that go bad, repace them with 680uF 16 v. 105C. the capacitors are clustered together. on the DM board the DM board is the board that is enclosed in the metal box. the repair is not an easy one so have a tech help you. this is a known problem.

My guess is trapped air in the cooling system. If the cooling system was just filled with antifreeze without bleeding the air, it could cause sporadic overheating. It could also be the cooling fan not coming on at high speeds. Next time the temperature rises, turn on the defroster for th front windshield. That should cause the air conditioner to come on, which in turn will turn on the cooling fan. If the temperature drops, I would suspect the cooling fan sensor is faulty.
Does AC turn on at all? if yes, remove front cover, do coils get cool at all? if no, thermostat may be bad telling unti that the desired temp reached is satified.. or.. you have the desired temp too low, if you have it set for 75 degrees, and it is 72 in your house, the fan will run and no cool air will be present.
I'm assuming the screen is not blank, and that you can select heat/cool and nothing happens. If it's battery operated then there probably is an issue beyond the t-stat. Technicians normally remove the G or Y wire from the thermostat, then jumper or touch the G or Y wire to the wire that's connected to the R terminal. If the indoor or outdoor unit engages, then the t-stat is/may be the issue. Lots of help out there for testing/bypassing a thermostat. If you're t-stat is battery operated, there is probably an issue that's at the inside unit, like a low voltage short that opened the low voltage fuse, or many other reasons that would cause this scenario. I'm not sure if this will help you, bit you may need a technician if it's not the t-stat.
Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.
If the refrigerant has been accurately charged and diagnosed, I would look for an air restriction. Check your filter first of all. It sounds like it may still be trying to freeze up. Make sure all the vents are at least a little open and the return grill is not blocked. In the Rocky mountain region we like to see around 44- 50 deg. at the vents. 65 would tell us that everything is not ok.
Operate your air conditioner with the fan in the on position. But first turn the fan on, turn the temp up or shut the cooling off. Your coil is more than likely frozen over. At night when outside temperature drops the refrigerant pressure and temperature in the system also drops. This action can cause icing of the cooling coil, with the fan in automatic everything shuts down at the end of a cooling cycle. Thus no air movement to melt ice on previous cooling cycle.
