Your problem is that you have a problem with chanel 3 ???

If so...the problem is improper tuning (channel tuning also can be lost automatically)...

no problem with the remote or any thing else >> what you need is to re tune the channel...

if you don't know how to tune...you can look into the user manual...

reply if you want to know more..

thank you

Hi,

A couple of possibilities:

  • faulty firmware (flashing required);
  • channel memory erased (needs reprogramming);
  • depending on how cable signal goes in (VCR, tuner or Cable box), a probable fault in your incoming cable signal;
  • hardware problem which could simply be a loose connection, cold solder in in some cases, logic circuitry.
The last of course requires familiarity with electronic circuitry and components, use of a soldering iron and perhaps even a DVM. Should you be uncomfortable, then perhaps your best bet wold be to seek the services of a qualified professional.

As I have normally responded to similar concerns on probable cold solder issues, Additional information:
  • cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the TV turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.
  • Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have posted on then off then on, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

If your TV still does not turn on after unplugging , then you will have to retry for a longer period of time. Try longer periods of time such as overnight. And you must unplug the monitor from all connections that can supply power to the monitor. It is recommended to remove all connections. If still not working,then it maybe a loose contact or cold solder.

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....

Good luck:

    Resetting the TV
    If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

    NOTE:
    Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.


    1. Unplug the TV power cord from the power outlet.
    2. Unplug any connected devices (DVD, Set-top boxes, etc...)
    3. Press and hold the TV power button for five seconds.
    4. Plug the TV power cord back into the power outlet and turn on the TV.
    5. Open the on-screen menu to confirm that the TV is responding again.
    6. Turn off the TV and reconnect the devices.
    7. Turn on the TV.

    hope this may help;

    Regards,
    VOTIT

My suggestion is to buy a universal remote, which comes with instructions to program your remote to your tv, and you should be able to fix your problem

Good luck........

Have a close look at the cables between the converter box and the television set. Perhaps one is damaged by a tight bend or has a damaged connector.

OLDER MODEL RCA HOME THEATER PICTURE AND PICTURE


Hi Unykue,

I am an electronics technician who just happened have been given the same set as you because it was giving the previous owner the same problem. Since I am confident in my trade, I took the set and diagnosed noise in the remote receivers input to the cpu.

What this means is that a capacitor( or something) wasn't working properly and was either not filtering the noise out or it was introducing noise into the data stream that controls the TV through your remote control.

My fix was to essentially cut out the entire remote control input to the TV. Since I have a directtv box to give me remote control, I don't care if the TV's remote works anyway.

The way I did this was to open up the unit and find the front I/O board were the buttons meet the switches for power,chaennel, volume, etc. On that board there is a plug with white wires and one black wire. The two wires to cut are the one next to the black wire and the one all the way at the other end of the black wire. These two wires are easy to splice back if you do not like the results of this procedure so that there is really no risk of damaging your set. If you wish to verify the proper wires to cut, they are the two wires that come from the IR receiver's side of the board YET DO NOT GO TO THE OTHER SIDE WITH THE BUTTONS! There is one wire that does indeed go to both sides.

This may not be a perfect solution but it is free. I hope that this will help someone out there.

Possible power supply problem?


Yep i can tell you what it is. The High pitched sound is the power supply soound when its overloaded and thats because the Horizontal output transistors shorted and this happened because of the flyback transformer went bad and /or the horizontal driver coil right off the secondary of the horizontal driver transformer and then the other side of this coil connects to the base of the horizontal output transistor. The part transformer cost about 35 to 45 bucks to the dealer and the transistor cost about 15 bucks. the total repair job cost about 175 to 225.00 after all said and done and some shops even may charge more ad there labopr rates may be higher. Good Luck
