    Dear Slinteriors;The chassis # is CTC188AE and if it makes a difference this TV is actually an 80 in rear projection and the Model # is PS80690 Thank You for your time in this matter.

    As I am not well versed in TV repair... Is this something that I should do myself ?? I do have the original service information sheet that is left in the set.For the main chassis I have located the HV start filter device # X C4759K Is this the same thing as the HV Block. It is the only item on the service sheeet pertaining to what you have mentioned. Also there is nothing on the service sheet with regards to a flyback, so I do not know where this is located either. Thanks again.........Pytbl

  • pytbl Mar 03, 2008

    Slinteriors;

    I have done as you suggested and checked the HV Block and the set is still doing the same thing as before. Do you have any other suggestions on whatto check next......

    I have the same problem: PROSCAN model: PS80690,S#633680029, chassis#: CTC188AE. Power won't turn on. I saw 2 PCB's with burned smd resistors |(PCB with 6 arrays of Al heatsinks, and a metallic film resistor (orange, white, orange, black; 1 W) with 1uF, 100V polarized capacitor (PCB with connectors/wires going to the RGB tubes with one red connector going to the PCB mentioned above). Besides this PCB's with burned elements, is there others I should check? Are these PCB's available as an assembly to change the whole old/broken PCB's?

    Power wont turn on. I found 2 PCB, 1:PCB with Al heatsinks in 6 arrays, and 2:PCB with red connector going to PCB as mentioned 1. Is there an assembly of these PCB's to replace the old/broken PCB's 1&2?

    Hi, My PS80690 doesn't turn on. The power light blinks 3 times, and the set never comes on after you push the button. I would begin to troubleshoot it, starting with the power supply, but I can't find a manual. If anyone would know of where to obtain a manual, I would appreciate it. Thanks Stan

    That chassis is famous for have the HV block go bad. The test for that is to remove the lead from the HV block that goes to the flyback place the lead into a dry glass bottle where it will be secure then try to power up the set. if it doesnt shut down your HV block is bad Part # 205064

    You would have to next start troubleshooting the power supply. You will need some skill as well as a complete service manual to tesy various votages at the various test points. It could be just a diode or regulator transistor causing the set to shutdown. Its not real difficult but you would have to know how to test transistors and diodes with an ohms meter. Do you have an ohms meter?

    Thats a hard manual to find. I am still looking. You will ned the manual to even begin to troubleshoot.

TV Doesn't Turn On
  • Your RCA rear projection TV may not turn on from time to time for several reasons. First, check that the power cord is plugged into a working power outlet. Check that the outlet is receiving electricity by plugging a different device into the outlet. If the other device doesn't work, you may need to replace a fuse or reset a circuit breaker in your home.

    If you tried using the remote control to turn on the TV, press the "Power" button on the front of the TV. You may have a problem with the remote control if the TV turns on.

    If you tried using the front control panels and haven't tried the remote, press the "Power" button on the remote control. The television controls are blocked if the TV turns on with the remote. To unlock the controls, open the "Parental Control" menu and remove the check mark next to "Front Panel Block."

    Finally, your TV may be performing a diagnostic check. These checks are used to find any errors in your TV. Wait a few minutes before trying to turn on the TV again.

TV Turns Off By Itself
  • You may find that your RCA TV turns off by itself on occasion. This is often because the "Sleep Timer" feature was enabled. This feature allows you to place a timer on the television that will turn it off after a specific amount of time has passed. The feature allows you to save on your energy bill and extend the life of your television.

    If the "Sleep Timer" wasn't set, the television may have detected a power surge in your home and shut off automatically to protect the components of the television. Wait at least 30 seconds before turning the TV on again.

    Finally, if you suspect the television is turning off for a reason other than a power surge, unplug the television and let it sit for at least 10 minutes. This will clear any errors in the television. After 10 minutes, plug the television back into the outlet and resume normal use.

  • Blank Screen
  • A blank screen on an RCA rear projection television is usually caused by a loose connection or an incorrect setting. Check that the coaxial connection on the back of the television is secure or, if you're using an external device such as a DVD player, the video cables are secure. Press the "Ant/Cable" button to switch between tuners if you are watching television, or the "Input" button to switch between input channels if you're watching something from an external device.

Your problem is most likely in the main power supply or possibly in the sweep power supply. Without the know how and a service manual, you could turn a minor problem into a mojor headach.. LOL Play it safe and invest in a pro to assist you in this repair. The 'rough' ride might have loosen some connections.
