Tv doesn't come on

I recieved a rca tv model g35302wk and when i first got it it would turn and go off a few seconds later. if i waited ten minutes and tried again it would come on and go off the same way. but now it doesn't do anything when i push the power button. i checked the fuse and it is good but on the bottom of the circuit board i found a few solder joints that have a bunch of brown stuff around them and on top of the circuit board i noticed that around the some of the smaller capiciters looks like it was stained by something. i didn't see any capaciters popped though

The brown stuff you see is excess flux and is not hurting anything,you need to check the horizontal output transistor for a short,sometimes this transistor goes bad because loose conections in the horizontal driver transformer and could have been intermitant,if the transistor is shorted it likely took the safety resistor that gives him the volts to operate.It seem you are familiar with tv service but some measurements need to be made with a meter to check for a short.If the transistor is bad it need to be replaced with an exact replacement,check for loose conection anyway very carefully,some are hard to see.

How do I program this RCA nightclub universal remote for my Samsung smart TV

First understand that you need a little patience with this remote, it's a little slow, it may take a few seconds in between pushing buttons for it to react to your TV.

1)
-Turn on TV manually first.

we're going to try and get the remote paired to your particular tv

2)
-Facing RCA universal remote towards TV, press and hold both the POWER and TV buttons on the remote at the same time.. until the RCA universal remote POWER button lights up and is constantly on.

-Then press the PLAY button on RCA universal remote

(POWER button on remote should be blinking after pressing PLAY -- what the remote is doing is trying to program your TV with a list of codes. if your TV does not automatically shut off after a minute, press the PLAY button again. your TV should shut off. wait a few seconds before trying to press PLAY button again if you need to try again.)

3)
Assuming remote turned off TV. Now let's try to get the remote to turn on your TV

On the remote at top right is a REVERSE button, press that. You should see the POWER button on the remote blink once in response to you doing that.

Watch for the power on light on your TV.. your TV may take a few seconds to power on..

Wait a couple seconds. if your TV has not turned back on, press the REVERSE button again. the POWER button should blink once again in response

If your TV did not turn on. You may have to repeat pushing the REVERSE button waiting a couple seconds for the remote to try turning on your TV. For some people this can take several times, if not a dozen times. Just be sure to be patient and wait a couple seconds in between pressing the REVERSE button again. (what the RCA universal remote is doing is going through a list of codes trying to find the right model to pair to)

4)
Assuming the remote finally turned on your TV.. We are almost done. We programmed the remote to turn off the TV and turn on the TV. now we want to press the STOP button on the RCA universal remote to lock in those codes into the remote. After pressing the STOP button the light on the remote POWER button should turn off.

5)
We are done. You should be able to change the channels and raise and lower the volume of your TV.

Rca HD61LPW42 -- we just replaced the color wheel. now we get a picture but only for a few seconds. then it turns off and after a few seconds restarts. this goes on indefinitely. a couple of times...

Hello

If the power light blinks slowly,

you've tried to turn on the TV during

the lamp cooldown cycle. Wait

approximately 30 seconds, and the TV
will turn on automatically.

If light blinks, pauses for about a

minute, and blinks again: the lamp is

trying to turn on (TV will turn on

when successful). If TV doesn't turn

on and sequence continues, the lamp also
needs to be replaced.

To order lamp call 1-800-338-0376.

Have your TV serial number

and lamp type available (you'll

find this information on the

sticker that's on the right side of
the TV).
OK.

My rca r52wh74 turns on for 10 secs then off.

was the storage unit climate controlled? If not then it's most likely due to heat and or humidity in which case I would suggest cleaning out the tv from the inside if you want to spend the time to do so but there is a good chance that the tv will need to be replaced.

RCA HDTV model#HD52W59. When I turn the power on it stays on for a few seconds and then goes off by itself.

TV turns off unexpectedly
• Sleep timer may have been activated.
• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then turn on again. If this
happens frequently, the voltage in your house may be abnormally high or low.
• Unplug the TV. Wait ten minutes. Then, plug the TV in again.
