    electech1, I am a novice when it comes to front boards and main boards. I don't suppose any pictures are available?   Thank You

    Electec1, Where can I find the example of the front board?   Thank You

  • trouble266 Nov 10, 2008

    Electech, I can hear a clicking sound around the area of the power supply when the tv turns off.

  • trouble266 Nov 10, 2008

    Thanks for your suggestions, but unfortunately I don't know what the vertical IC, etc. are.
    Guess this is above my technical capabilities. 
    Thanks again for your help.

    I have 2 (yes two) of the 27 RF50 TV's, and neither has a picture. Both have horizontal lines moving accross the screen. The authorized repair shop wants $50.00 to look, then plus parts and labor.

    The TV sets should have lasted longer.

Ok , first you will need to check the controls panel on the front board, take it out of there and make sure that the buttons are not being pushed on and check the sensor for a short or open also the contact switches are not making continuity(short) then also unplug the controls panel from the main board
and please give me a fixya rating so that i may continue to help you with this problem( anything other than a fixya rating hurts our rating as a fixya expert) that is if you belive that my help will be beneficial to you, thanks

    i can show you an example of the front control board, and how one plugs into the main board , the rest will be you looking to make sure the front control board is not doing some things and of a couple of tests on it with the meter , also you will need to give a fixya rating so i can continue to help , and if you are not happy with my help you can always change it , and that rating also hurts our score , sorry but thats how fixyas doing the rating , so otherwise i will be glad to continue to help you find the cause of the problem as long as you want , thanks

    can you change the rating you gave me? this is a main board

  • jason Nov 10, 2008

    front printed control panel board( contact buttons and sensor)


    how it plugs into the main board


  • jason Nov 10, 2008

    ok then you probably have to replace the vertical IC , but you need to check resistor value in the power circuit and vertical section , also check electrolytic capacitors in the circuits

    check that out then let me know what you get from testing those ,but definately check capacitors and resistors for right now

If it is a "minor" convergence problem you can adjust it by going to the menu and scrolling to convergence and follow prompts A cross will appear when you have reached the correct place and you do the minor adjustments as it says. If picture is bowed you have major convergence problems.

Relay "Chatter" with good picture and sound


Sanyo Model AVM-1304 This TV has a loud mechanical "chatter" (or clicking)that appears to be coming from RL001 on the motherboard as soon as ther TV is turned on. I can feel the mechanical vibration on the component. The Picture and sound are very good. The chassis is G6Y-13040. Any ideas?

RCA F27650 27" TV - Snow Bursts


The model you listed, F27650 uses the new ATC113 series chassis, which is only about 3 years old. The ATC113 chassis is not known to have snowy issues, but if yours is then I would suspect that a solder joint is loose in the tuner. If your set is actually around 9 years old, then it might perhaps have the notorious CTC175 - CTC187 series chassis, which went snowy all the time due to cracked solder joints on the shield grounds around the tuner and microprocessor. In either case, some good quality resoldering should cure your trouble. If you have never done fine solder work on PC boards with small surface-mount parts, allow a qualified tech to handle it for you.

Video will not turn off; "I2C-BUS STOP MODE" error at power up


Nope a very easy problem .. What it is is the relay is stuck on or closed so when you plug in the set the power comes up But the micro hasent told the rest of the set to work yet. So when you hit the power button. its just like you hit the power and it activated the relay and the rest of the set. Now in some rare occasions the driver transistor for the relay was shorted But most of the time its the contacts that weild shut, but you cant just clean them as it will work for a while, but in a month or so you will be in the smame boat. But if you not a tech this repair shouldnt cost you to much because if your not an experienced tech you can not only cause harn to the set but also you yourself BE CAREFULL and take the set to a pro!!!! Good Luck
