LG RP-21FE85G
Horizontal output transistor q402 (tt2170) shorted, fusistor fr403 (1.2ohms 1w) open. Cold solder on the horizontal output transformer t403, causing the horizontal frequency not to reach the horizontal output transistor, burning it. Re-solder the transformer, install another horizontal output transistor and another fuser. I installed some tt2170, they all burned instantly and opened the fusistor too. probably counterfeit transistors. I replaced the tt2170 with a bu2520dx, it didn't burn anymore. As the bu2520dx is bigger than the tt2170, I had to make a hole in the heatsink to adapt it, but it worked perfectly. Rgs011
LG 43UN7300
Turns on but no image Shorted screen Look for the lockout12 point on the right side of the vcon, count 9 tracks from right to left, isolate one track, it will be a little scratchy, but it is usable HAHNRAHN

LG 14CB25A
MC-059A 		Vertical closed (I solved it, and the TV stopped after a few minutes), it wouldn't turn on with the stand by LED blinking (I solved it due to a leaky zener diode), low sound/audio (I solved it by changing capacitors). presented three defects in this sequence Closed vertical: r301 of 15k (was changed to 22k, close to vertical); did not turn on: zd851 (6.2v) connected to the photo coupler pin.; low sound: c504 (near the varicap) and c602 (near the audio aid). This one took work, but we did it. check and replace the aforementioned components; good luck. Eletroboy

White screen, functions don't work Rewriting of ic 802 atmel 24c64a memory, they sell the data on the internet. Marcelo
LG 22MA22D 26MA33D 28LN500B
EAX65374603 (1.3) 		Monitor does not turn on Chip responsible for the 1.2v line ic803 (mp2315) visibly burned Replace the IC, which is an mp2315, or place a linear converter or some other 1.2v voltage regulator on pin 3, which goes to the 1.2v coil. To test if this is the only problem, simply remove the burnt IC and inject 1.2v into the L801 coil, this coil goes directly to the processor, so be careful not to get the voltage wrong. a simple 1.2v 1117 sot-223 regulator will not work as the current is quite high.
