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.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

At a steady 65 mph, the torque converter clutch (TCC) is engaged. When you accelerate, the ECU disengages the TCC to gain extra torque for acceleration and then re-engages TCC when speed is steady. Its kind of like having an extra gear.
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.
An A/C unit is a dehumidifyer BUT Unit are rated in Pints of water, a Unit in Florida might need a de humiditiyer connected to it, the air is heavy with humidity. Another reason is that the Unit is under sized or not allowed to run long enough (?) Infor. on what State you live in would help and the size of the apt. or house the unit is covering. The best T / H would be 70* and 55 H and that would be on the cool side for most people , avg temps in a house would be 74* 65%, body temps are 98.6 most A/C unit are rated at 90* amp temp ( outside ) if the condenser is dirty this will cut the performance on a hot day over 85* Keep unit clean -replace filter (s) . If your getting a 15 degree reading between outside and inside your doing good the best would be 20 degrees ( depending on heat load) windows, and sun. Actic fans remove 30% of the heat -it will drop the temp from 120 to about 85, this can save you a lot of money in A/C bills and help cool the house in warm day when you don't need the A/C.
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.
