So anytime you can use a 12 volt appliance and avoid having to use your inverter, you will always be ahead in the power usage game.įor those RV’s electrical systems that have a big enough solar array and enough battery capacity, this loss of power thru the use of an inverter is not big deal. In other words, there will be wasted energy. The inverting process isn’t 100% efficient, so you will always have a loss of power in this process. The process of changing 12 volts of power (the inverter input voltage) to 120 volts of power (the inverter output voltage) results in loss of power (as heat). Hopefully I can clarify the power draw question.Īnytime you are running an inverter, you are having a certain amount of wasted power. And haven’t had an issue with the mount itself (just the way it’s mounted to the wall). Which is the kind that I’ve had for 6+ years in my rig, using it full-time. Unless I’m mistaken, that’s the kind we show on this page. Not sure what you mean by rigid swing arm style mount. Or, go without a TV and enjoy nature and family time? Yeah, I know, there are times when a TV comes in handy, so maybe go with a cheap 120-volt TV and see if it stands up to the rigors of travel so you don’t have to sink a lot of money into an RV specific TV. If it was a 120-volt TV, did that work for your style of camping (plugged into shorepower)? If so, go with another 120-volt TV of MUCH smaller size that won’t be such a dead weight bouncing up and down on a VESA mount. Was the 40″ a 12-volt or a 120-volt (household) TV? But that’s a lot of weight to hang off a VESA mount on a vehicle that bumps its way down the road. I think this must be a software problem with the Eeprom unless those better experienced and knowlegible than me can see this being caused by something I am not thinking of.Forest River put a 40″ television in a 24 foot Class C RV? Whoa! I guess they wanted to razzle dazzle buyers. However on every third attempt of turning off then on at the wall the 12v displays then rapidly drops down to near 0v and if I press the Power on or remote at that point the set comes fully to life. When i turn it off at the wall instead the voltage obviously plummets straight to 0v and if I switch it back on at the wall the voltage measured at D3 goes to 12v and stays there! - pressing the Power button when the reading is this 12v wont let the set fire up. If I then press the P on button or remote while these readings are either 12v or 0v the set wont come to life under any circumstances. I find that when I have the set actually working and I press the Power button to put it into Standby the red light comes on but 12 volts remains across the board through D3 and supplying the v regs for some considerable time and then drops to 0v. Still doing more measuring but not complete yet. I think I have now shown the V regs not to be the problem as they all work fine once power actually reaches them down the circuit. Thanks Comptek (looks like your close to me - I live in So Shields!). I would be extremely grateful if anyone has hit this problem before as i have never seen such especially with the power coming from an external psu or can point me in a new direction or highlight a component that can do this. ![]() I assume from the symptoms some faulty component is requiring the external voltage to be removed so the standby and red light dies before it will reset itself and then only after several attempts. ![]() Have also done a full system reset - which showed no improvement and now seem to be out of ideas. When at standby the board shows 12v and 5v standby alt all the relevant test points and when the tv finally comes to life every marked voltage on each board point measures exactly what it should be. Have removed and checked every cap on the mainboard and all are fine. When told these were the symptoms I was a bit cynical but sure enough nothing else seems to get the tv to work other than the above procedure.Īs the set is powered by a "power brick" supplying 12v it was easy to substitute various other 12v power bricks but all work as above. Switching on and off several times at the wall and then pressing the Power on button or remote sees the tv come fully to life ans stay that way with all functions working and a superb picture and sound. ![]() Pressing Power on or using RC fails to bring it out of standby. When switched on at mains the standby light comes on solid red. My latest acquisition is this LED Tv with the following symptom.
