Re: the lg 52SX4D dlp tv

Hello all,
i have a 52sx4d and mt issue was that component input are not showing and i have no sound. i had a LG certified tech come over only to make it worst. he came to replace a main board and no it does not power on. 3 trips later and 2 replacement main board and a power supply later its still does not power on. and he said LG said to replace the same two parts. i looked at the cage were the part is and i think that he shorted out the boards, why because there are at least 4 connectors that are the same. so i am looking for a diagram so maybe i can connect the right cable to the right connector. can anyone help. also the power light blinks about 100 times then it stops and if you try to turn it on the lamp light blinks.
PS. the lamp is new
thank you all in advance for any help you may provide

HAd the same problem with mine, but was under warrenty, they took it to the shop and had to replace the Engine if you need the specific engine name I can look it up, now the bad news if I would have had to pay it would be over a grand for the part alone.

Lg 52sx4d problem

If the red light scrolls through, you need to replace the bulb. I replaced the my own bulb, and when I tried to turn on the tv the light kept scrolling. What was wrong? I DIDNT FULLY REASSEMBLE THE TV AFTER REPLACING THE BULB.

Make sure that all the screws are put back in and it will probably work if you have replaced the bulb.

LG DLP 52SX4D/Will not power up

Ours did the same, it was the colour wheel in the tv, it was stuck [from dust and smoke] and the tv wouldn't go past that problem.
