Hello!
ATT! First you need to read "1.1 Safety Precautions" from attached Service Manual.

1. Download and Read Service Manual

2. Search on Youtube for "UA32EH4000 trouble"

Good luck!

probably needs filters cleaning or a new lamp replacement.

Try to download its service manual and refer it. Some paid download sites have service manual to this set. No free service manual available now. Try paid downloads.

Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it on.

Solution: I just had one of these come in. I opened it up, and found the U501 capacitor a little suspicious looking, in that it had a deformed top. It was a 470uF 16V electrolytic 105degC 10mm x 12mm. I replaced it with a very good quality 1000uF 16V electrolytic 105degC 10mm x 16mm Nichicon UHN1C102MPD. After that repair, when I tried to turn it on, the LED was yellow for a second, then green, then I got a picture, and it appeared to work great. I then asked the owner a week later how it was working, and they said it was working just like new!
