I have had the JBL Partybox for over a year now and suddenly after pretty light use, it just stopped turning on.

The Power light illuminates orange so i know its getting power, I have opened it up and made sure all the ribbon cables and connectors were snug. I also have re-flowed and measured the power switch on the circuit board just to make sure it’s not the switch.

I can’t test any sort of power or connection since I can’t turn it on unfortunately.

I can’t seem to find anyone having the same issues as me so I am hoping I can find some help on here! Thank you in advance.

I have taken off the back of the tv and checked the power, main and t-con boards and all appear to be ok however tv is stuck in a boot loop unless I remove the ribbon cable from the main board to t-con board then the boot loop doesn’t commence the tv turns on as normal. Now for the confusing part…when I disconnect the ribbon cable, let the tv start up and finally reconnect the ribbon cable the tv works perfectly however once turned off the boot loop starts again until the steps are repeated. I have seen “fixes” on YouTube etc for a similar issue which uses electrical tape to cover 1 or 2 receivers on the t-con board this usually isolates a spot of led’s and leaves a visual defect on the screen. This doesn’t seem Like the correct fix for my TV’s issue as the entire screen works flawlessly when I have removed the ribbon cable and inserted it again. Is there any known fix for this or a way to stop the t-con sending the signal to turn the tv off? Thanks.

Prior to it stopping, it would work at half-mast. It is a design flaw. Apparently, the wires that connect to the microphone come loose. It is caused by moving the microphone boom up and down. I can't find anything on how to break it down to access the wiring. Any help is greatly appreciated.

I saw the teardown and repair videos of both devices and it seems to me the only significant difference is the prescence of the pointless "iPod loop" on the touch 5.

Can anyone confirm whether I can swap the casing between them? thanks in advance

after 13 years the LED of my beloved Philips TV 55PFL7108K/12 suddenly started to blink twice.

Then i couldn't turn it on anymore, therefore i re-plugged the power cable. Since then it doesn't even blink anymore at all. Only when i plug in the power cable the LED lits up for some milliseconds and then everything stays off.

Any idea what this could be? I am willing to open the TV, but for now i wanted to ask here for ssuport.

Thanks a lot in advance.
