Hi, i'm looking for a 17MB12-2 dump for a 26" (Bush IDLCD26TV27HD - although any 26" will do).

I'd appreciate any help, or alternative dump suggestions.

Please i need help for favorit tv motherboard is VESTEL 17MB60-3  i no have signal on channels digital analog too  like dead tuner
tv working in menu i have picture no have another problem  :sign0085:
It would be nice to know if tv was still working after replacing the backlights

Excellent! yes, one tardy LED is enough to induce the problem. I reckon you've got it licked.
Hi Bruce,

I replaced the Power board, but to my luck, the replacement P. board only lasted for two days, after which, it completely went out. This time, the red stand-by light also disappeared (this wasn't an issue with the original board). So, I re-installed the original power board for time being.

I replaced the old backlights with a new set. I did carry out a test on the old backlights, they were all working, but, one of the LED, even though, it lit-up, but had a few nano-second delay (nano second flickering). Let's see, if this new set of backlights resolve this issue, at least, now I can rule out the Power-board and the backlights.

Thank you for your reply and help. You have been very helpful!

I don't have the service manual for that model - doubt it would have the psu schematic anyway. Standby is mostly generated by a small 8 pin IC next to a small transformer, usually supplied by a small bridge rectifier connected permanently to the mains.                Bruce

You ordered the LED strips without checking them first? I hope they were cheap.. Most likely a bad connection, but at least you may pick it up when you strip the display panel. Bon chance.                Bruce

Hello Bruce,

Thank you again for your reply and advice. You have been very helpful. You are right, it may be the faulty LED backlights. I have ordered a new set of backlights and waiting for them to be delivered. In a meantime, I have gone ahead and changed the power board as well, as they got delivered the very next day and easier, plus, economical to replace. Anyways, let's see if a new set of Backlights and a power board would resolves this issues.

Thank you very much! and really appreciate! your help and inputs.  :c017:

Personally, I'm now putting my money on a fault in the LED strips. Might be time to disassemble the display and inspect the backlights. Seems the
slightest tickle restores backlights. The backlights will still operate with the display and diffuser  sheets removed. Have a poke around the various connectors.                              Bruce
