Re: Sanyo FW55D25F stuck in color test mode

Pin 18 i have notice that myself and am looking into it. Ive been trying to trace out the connector on the power board that runs to the main board. I need to try to figure out what is what there then see which pin they lead to on the main board. Try to see where pin 18 is coming from there. Maybe it's something that doesn't have power. Just got my florescent lights put up yesterday so now i can see what im doing. Just got to find spare time from normal work, stuff around the house and honey doos to get back to looking at it again.

Re: Sanyo FW55D25F stuck in color test mode

how about this combination / remote sequence.

quote: "Press the power key first. If it does not solve the problem, then press the
keys on the remote control in the order shown below to change the unit
to the live mode.
SLEEP L PIX SHAPE A L K L H L I L B"

certainly unusual... I don't know if it applies to your particular model but who knows. You got the user manual for the set right.... :-)

Re: Sanyo FW55D25F stuck in color test mode

not sure where the letters in the alphabet are on the remote but i tried converting the letters into numbers that you would see on a phone. That didnt work. where does the L A L K L H L I L B come from? how do i convert to what is on the remote?

Re: Sanyo FW55D25F stuck in color test mode

Just my 2 cents.
Disconnect cable (LDVS) between the main board and the panel with integrated T con.
Jumper power from the power board to the smd fuse on the panel. You may need a ground path also. Turn set on.
If your still in test mode, You have a panel problem

Re: Sanyo FW55D25F stuck in color test mode

To turn off self test mode, first stand near your TV’s power cord going into the wall. On your TV remote control, first press the arrow up button then the arrow down button. After pressing the remote buttons, unplug your TV from power within 5 seconds. Wait 15 seconds and plug the TV back into the power outlet. Wait 10 more seconds and test the TV to see if the issue has been solved. If your TV is not working correctly still, repeat the complete procedure but press the left arrow button and the the right arrow button instead of the up and down buttons.

You could try getting a mainboard, saw some on ebay for about 50 bucks, seems like you need to make sure you match up your serial numbers like DS9, DS5 etc.

Maybe shopjimmy sent you a bad chip, they don't do refunds on those but they will probably send you another one with no charge.

I tried what you described and nothing happened the screen remained black. 12 volts to fuse and board grounded.
