Tv won't turn on - power SUPPLY OK

Firmware failed while updating causing u to "brick" ur tv

Good day!!!

if you have power problem without blinking lights or standby lights (red) the possible problem is power supply board..However if the TV have blinking or standby light but won't turn ON..there are multiple cause of that and need further troubleshooting..

tda9380ps /n3/3/1664 using in sharp tv power supply ok ,but no EHT ,the power LED are glowing red light press program key to change green light to return in few miniutes to standby in red light

First: service manuals http://elektrotanya.com/?q=showresult&megnev=lg&megnev2=32lc2du-u3%20&kategoria=tv&kat2=all
Second: most failure in power supply module is due to bad caps with domed top, you should inspect for that first, main AC fuse for main power.
Did you take out or look at the power supply yet?

The 32lc2du inverter is 6632L-0208B and I have seen units where it was the power board and others where it was the inverter.

Hope this helps!

Power supply problem.... I can explain to you how to fix via email with detailed instruction and pics... Hope you haven't bought another as this is a 5-30 dollar fix. I have 2 50" that did this I fixed mine for 80 cents.

Marine on a mission to help ppl fix their spendy sets and not waste their time and money spending hundreds of dollars on a 2 dollar fix.......

Not only have I fixed 2. I've bought a few at rock bottom 125.-250. and fixed them for 40 sents.

I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.

I would need the model number to look service codes

It is the power supply. Replace the C97, C19, and C16 Capacitors with 2.2 uF ones.
