the answer is no. here is a link to instruction manual.

55 is not the model, 5.1 sound but I will take your word on jacks many cheap TVs have only HDMI , no RCA jacks Video/audio in/. and I see yours has the 3.5mm phone jack style AV in well that really is Audio left/right sound, TRS so all you do is buy a RCA 2 CABLE audio, TO 3.5MM ADAPTER AND USE THAT. pick the gender of both ends. 2 cable to 1, not 3to 1 . https://www.fixya.com/answer/answerpageslideview.aspx?thid=29885463&ctg=465&brd=298

Hi Ward. What's the model of your TV? Some models of Funai sets had issues with the connector that goes to the button/IR board, since it worked before it was moved, I'd try that. Unhook the connectors and hook them back up, depending on the model and location sometimes these are hard to reach. If that doesn't fix it try unhooking the connector going from the power supply to the main board.

Been damaged/wires moved etc etc.

Might be of back-light fault. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ https://elektrotricks.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

say the word drying it is not RCV radio. at all , posted to TV video the dryer vents are clogged or vent screen or inside the dryer is full of lint and ever cleaned. (dismantlement) RCA 3.75-cu ft Ventless Electric Dryer (White) I have no idea how ventless works seems like fantacy but there will always be lint so we know that , so how do they manage lint, (a filter is the only way ) so clean it. it shuts down from sensors inside seeing it oveheat. if not filter packed it needs tech service,

You installed the wrong board, it's common to see 3 or more non interchangeable main boards on RCA TV's the main board matches the panel, different mains for different panel. It won't be a firmware update.

what input did the store use, what input are you using. you may need to go to setup and select the input you will be using.

Hi Tony, I bought a board from TVPARTS in Canada and now I have the very same problem. I have a 55" RLED5536. What is your model? The man at TVPARTS said the board has to be reset by a technician and I can't do it at home I asked him why didn't he reset it before sending and I received no answer. There is no reset button. I have tried the reset by holding power button after unplugging the TV and that did not work. I cannot reset it using the menu. So did you buy it from the same store? Did you replace the TCON board too or just the main board? Most of these main boards come from Canada because RCA is owned by Curtis.

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

HI, I'm not familiar with this brand set but in most cases, you can't replace a main board from another size set and have it work. I'd get the right board and see if that fixes it. I'd say the power supply voltages are ok, anything within 10% of rated should be ok, but the voltage to the tcon doesn't sound right, again a main board issue.

In order to help I'll need the model number

Your TV has gone into service mode now and the colours that are showing up on the TV screen is a test pattern.To stop that yo need to unplug the TV from the power outlet and the wall and hold down the power button for 20 seconds.

It's your LED lamps that have failed but on a smaller set like this it may not be worth repairing as a new set is real low cost

That has to be one of the longest questions I've seen on here but unfortunately it doesn't help figure out what's going on, you've replaced the power supply a couple times, but you didn't say anything about testing the 5 and 12 volt rails to see if you have the correct voltage and if it's free of ripple. Have you tested the "on pin" on the power board to see if the power supply is being commanded to come out of sleep mode and turn on? Another thing to test is the on command to the main board, I'd have to pull a service manual to see what it should be but generally it's around 2.5 volts on most Funai brand sets. To be able to repair a TV it generally takes some electrical engineering knowledge and takes more than just replace some boards and hope it helps.

Hi Keith, your set has two backlight circuits, one side sounds like it's working however the other string has at least one diode that's either open or several that are shorted, and the overload section of the backlight inverter are shutting down the negative side of the supply causing no backlights. This is why you see one side come on for a moment then shut off, new strips will fix the TV

backlight may have gone if your tv has one
