[Solved] Sharp LC-32D44E-BK TV: Troubleshooting No Power, Green Indicator Blinking, Red Light Issue

Hello.
I have a Sharp LC-32D44E-BK TV.
At first it turned off after a few hours, then more and more often, now, after turning it on, the green indicator lights up for 5 seconds, then it blinks once and lights up red.
The screen is always black, no reaction whatsoever.
What could be the reason?
Something can be done, I feel sorry for it to be scrapped.
best regards

What have you checked so far?

Capacitors
The two suspiciously bloated ones were still unchanged

Hello,
I have the same TV and exactly the same fault except that the TV stopped displaying the image overnight. I checked the power supply / inverter module, soldered everything I could, checked the capacitors and some diodes - nothing. After switching on in the service mode, the image appears correctly but goes out after about 15 seconds. Interestingly, the image is without backlight. From what I read on the forum and watched in the movies, fluorescent lamps are to blame for it. There are 10 of them and some or all of them must be replaced. For now, I am wondering if it is worth it because it is quite a cost and the risk that something is not working yet.
Best regards.

I have worked this model prenat times, you need to disassemble the matrices as soon as you need to replace the pink fluorescent lamps, as for the big one, it is best to replace a set of 10 fluorescent lamps, the quality of its image is practically not comparable to any LED.

Hello.
I replaced the fluorescent lamps. The TV works nicely. Lamp and Standby errors cleared and the letter K removed in accordance with point 5 of this post from the forum:

I only have a question when searching for TV channels it asks me for a four digit code. "Na lime" I entered the standard 1234 and everything is fine, but is it possible to somehow remove this PIN question process? Do these receivers have that?
Thanks for helping with these fluorescent lamps.
Best regards!

Hello
Maybe someone is interested in this TV for a pair of zlotys
It is a pity for scrap, or rather, I will leave the fluorescent lamps and I will not replace them

It depends on how much, because in the pawnshop it is operational for PLN 250

I deleted the TV
