Sharp crt 21sfx10a only on stby blinking
-
Hello, on Sharp LC-40LE830E is everything OK. Working great. If I put the 230 V off and on again, it just blinking white standby LED. I can power on only via VOL- and CH+ and POWER button on TV. After that, I can power off and power on again without problem (by buttons or remote control) until the 230 V is connected. If i put the plug off and on again, just white standby LED blinking. TV needs three button starting again.. On the first look, the backlight looks great, no darker or lighter spots. Any idea what is wrong?07-21-2023, 09:05 AM -
Hi everyone,
I've got a Sharp LC-55N7000U. It has a standbuy LED when plugged in, but powering it on causes it to blink 1 LONG and 5 FAST. Theres no display and no backlight.
Nothing I checked has that blink pattern for Sharp TVs and there's only one multi-button on the TV itself so that service menu trick involving the input button doesn't work either. Its a post-Hisense buyout TV so that probably makes sense lol
I've tried disconnecting the panel sides from the TCON alternating sides, but no change in behaviour even when the whole TCON is disconnected,... -
Just picked up this sharp tv not too long ago and it started not wanting to start the other day, giving me the notorious 2 long-5 short blink pattern indicating a power issue. I was able to force start it a handful of times (once the tv has fired up it has no issue running for 5+ hours). But now as of yesterday, no matter what I try to do button combination wise, I just receive the same blinking code.
So I busted into it and have done the following:
-Removed the power board and inspected for any bad caps, burn spots etc. Do not see any instances of such ... -
Hi There!
I have a TV set (model TD Systems K32DLV1H) which doesn't power up.
During power off, the stby red led is on, as it should, then I press power button on remote and the led starts blinking, endlessly.
Sounds to me like a PS problem. TV is kinda alive as it stays in Stand-by, recognizes power up button from remote, etc, but can't really power up.
Internal PS is a 17IPS11. First inspection shows no damaged components, no swollen caps, and multimeter shows all diodes are good. Also there's a dual diode transistor shaped component on a heatsink... -
Got this SHARP AQUOS LC-70LE836S for free - did some basic troubleshooting, and found manual - without detail schematics though. Comes from a meeting room with extremely few working hours.
Symptoms :
When connected to mains, the logo blinks continously, approx 6 times per 10 seconds.
A press on MENU as per the manual changes this to one short blink, one long and then repeats.
Only 5V ( Standby ) on PSU module present, no AC_DETECT, no 12V, no 13V, no PS_ON from mainboard.
As I see it mainboard has some kind of life, but does not...
