This glitch is very strange. Initially it seemed to be a firmware issue, but in reality it doesn't seem to be.
With the correct voltages it is very strange that it doesn't work, with changed cpacitors and heated processor.

When you turn on the TV, does the standby LED turn blue and stay blue or does it turn back to red?

Hello all, Today I get almost the same TV just this time the model is LCD32V87, with the same symptoms. All caps in PSU is excellent. Changed about 30 capacitors in MB with high ESR 5-15 Ohm - nothing changed after that.
Here is the log:

When you turn on the TV, does the standby LED turn blue and stay blue or does it turn back to red?
 The old TV (it's still with me) and the new one exactly the same, after tunrning it on, blue led goes red-blue (4-5 times) and it stays on blue color. And even there is a reaction on panel sensor buttons, when I press something - they are going on, but no changes in terminal logs when pressing them, TV just feels when I am touching them. By the way I ordered CPU MT8222 but it will come in about 1-2 weeks, but this 2nd TV client can't wait so much. And yes, again no backlight after turning on and TV consumes 19W.

No, only TV N1, TV N2 was not working. But N2 is working now, after changing caps and with this SPI from your site sir "Hisence LCD32V88 main RSAG7.820.1637"  :obrigado:.
I tried the same with N1 - nothing changed. I also noticed that there is 0.516V on +1.2V in TV N2, and 0.044V dropoff in TV N1, in other worlds, in N1 we have very low resistance on line 1.2V and a lot of consumption and as I understand this voltage goes into CPU, because when I am heating CPU - resistance on that line goes lower, heating other components - makes no changes. So now I need to wait new CPU and try it on N1 TV.

I measured the resistance, on N2 (new TV) it's 112R on line 1.2V, and 35R in N2 (old TV), I also measured this with desoldered SPi and EEPROM - the same. Also measured some transistors and resistors on that 1.2V line - all is ok. So I think, it's the CPU issue, which is semi-died because of high ripples from bad caps. On new TV I only have bad firmware because of the same bad caps. Will test new TV 1 day before say goodbay to it.

Yes, i think CPU have problems.

Hello dear friend! After new CPU I have red artifacts, could this be because of non-contact on the CPU ground pad? I have changed this CPU with preheating board to 100 Celsius, also used low temp solder.

Its posible leak solder in cpu or a configuration issue.
You can try enter in service mode and check service menu if have good configuration.
But before check and clean LVDS cable.

Really, there where 2 leak solders between legs! It's working now, after 1.5 months  :brinde: :obrigado:
