SOURCE: FPA lock settings, No remote, can not power on TV

If you forget your password you can reset it. Make sure the TV is off. Simultaneously press and hold VOL< on the TV?s front panel and CLEAR on the remote for approximately 5 seconds. Enter a new password next time you access the PARENTAL CONTROL menu. Front Panel Lock 1. From the PARENTAL CONTROL menu, press the up or down arrow to highlight Lock Fr. Panel. 2. Press the right or left arrow to turn on (box has check mark) or off (box doesn?t have check mark) front panel lock. Of course if you don't have a remote that can bring up the menu I don't know how this can be done.

If the front panel lock is on, you will need a working original remote (or a universal remote properly programmed for RCA) to turn the set on. The IR receiver is next to the buttons on the fromt but the RCA IR receivers are very reliable, and I have yet to see a bad one in a modern RCA TV. Once you turn the set on by remote, you can enter the menu and turn the FPA off.

SOURCE: rca turns itself off and on and scans thru all the channels

I have an easier solution, First I want to thank those who posted the solution that the problem is on the small switch board mounted right behind the switches under the picture tube. I figured that might be where the problem was but it's better to to see it confirmed. I thought the problem was more complex like maybe an IC chip got zapped or something but there are none on that board. Only 6 switches, the infared sensor, 1 capacitor and some resistors. I am convinced that in my case at least the problem is caused by humidity. It happened last year constantly durring humid weather in the summer and only a couple of times over the winter when the air is dry and cooler. I did figure an easier way to disconnect all the switches without unsoldering. After you remove the board, flip it over to the solder side and see where the wires connect. You will see them labled GND - KEY - +5 v - LED and IR. The one you want is labled KEY. You will see on the other side this wire is second from the end . Just separate the wires a bit and cut it. That's it. Just be sure it is the one marked KEY. This wire goes thru a series of resistors and the switches and nothing else. Just cut that one wire and put a piece of tape over the cut ends and thats it. it's a lot easier then unsoldering all 6 switches. And if you do decide at some point later to replace the switches, it's easy to resolder the wires and tape it. I did it this way and my TV is working perfect. I was done in ten minutes. You can only control the TV with the remote but so what, thats all we use 95% of the time anyway. I hope this helped you.

Re:"shutdown after video comes up the green power light stays on but the set will not shut down while changing channels."


I do not think this has anything to do with logic circuits and video processing. When you stay on one channel the horizontal and vertical alignment circuit works more than if you change channels all the time.
This is just a guess, but have a look at convergence ICs. when you keep changing channels the power amp ICs (or transistors) go on and off, if one of them is defective it will overheat and shut down.
Other possibility is an internal tuner failure. Also test using a DVS or VCR.

No picture on dvd but picture on tv only sound comes out on dvd

Could you try to set your channel to 2,3, or 5 when viewing video from dvd. Or try search which channel will the video and audio will sync in tune. I think this is an old tv.

Hope this one helps.

Screan turned a shade of purple

I believe you have lost the green channel leaving only the red and blue. It could be an internal connection like a solder joint or connector, or it could be component failure from the CRT to an adjustment pot. Being the set is ten years old it wouldn't be worth spending a lot of money on it. You can buy a 27 inch TV now for almost what a repair would cost. If the picture was very good before this probem you may try to get it fixed cheap. Otherwise it probably wouldn't be worth it.
My 27 inch TV's (A Sony and a Sharp) are pretty old and I would fix them myself if the picture tube was very good.
This may be a very good time to buy considering the discounts being offered. ;-)).

Sony tv problem

You have a loose solder connection or two. If I knew the model number of the set, I could be more specific. I would expect the repair would run about a hundred dollars, so make sure the picture quality is great before going to the expense.

You will need a Zenith remote with a menu button
There should be a "hidden" menu. Before you access it, I want to warn you, do NOT change any values of anything you don't understand what it is or does. You can PERMANENTLY DAMAGE YOUR TV. Also, write down the original values of anything you change before changing it!!!!!
If you still want to proceed(at your own risk), here ya go.
1. Press and hold the menu button until
the menu comes up on screen and then
times out (5 - 10 seconds)
2. Immediately press 9, 8, 7, 6, Enter.
3. The set should now be in the service menu
mode. To access most of the features
selection 00 needs to be toggled from 0 to 1
4. After your adjustments 00 needs to be
toggled from 1 to 0
5.Feature 16 unlocks the auto-program (change to 0)

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer
