Re: LG 42ld450 blinking red light

i didnt reflow it properly, just baked it in house oven. wanted to see if it would work now that it does i know was for sure just main board and rest of tv is functioning fine. i have a buddy at a local shop will reball for $25 i might just go that route save $60 on getting a used main board off ebay.

so far nice tv , trying to find a way into service menu to enable divx playback. from what i have read i will need to get a universal remote to access service menu.

MENU on TV then MENU on remote, hold both for 10 seconds. You will need a remote: any LG remote made in the last 10 years should work.

Re: LG 42ld450 blinking red light

Yeah, you need a remote as you have to hold both MENU on remote and MENU on the TV. The local 99p store sells remotes which operate LG TVs. Do you have a similar shop in the US?

i have the factory remote tried holding menu on there and the tv at same time no luck. maybe the menu + menu is disabled on my firmware version have 3.05.20 on my tv.

I have 42ld450 with red blinking issue. When I was watching TV suddenly sound and picture went off. I turn off/on Tv but red light blinking continuously. There is no backlight, no picture or sound. I checked DC voltage output from powerboard, all seems ok. There is a switch on logic board, when I press it, backlights turn on for an half second then goes off. Do you have any idea?

Regarding the USB "hack" to play videos, see the comment section of this link:

"i have a philips magnavox universal remote. i programmed it to work with my tv. on the remote i have a prog/ guide button. when you press it, tv will ask for password, in my case is 0413 (latest firmware). the service menu will appear. go to tool option3 and change divx value to 1. DONE"

Cheers!

Hi, my friend has the same model TV which had the same exact issue.

We checked the power supply voltages, all fine. Then we measued all 3 voltage regulators on the main board (IC2700, IC8800, IC8901), which were fine as well.

So finally we decided there's nothing to lose and stuck the main board into a home oven preheated to 240°C for 3mins. Much to our surprise, the TV works now

It's a pity that the manufacturers have such a poor rate of failure. I don't think lead free solder helps.

I have 2 of this generation LG tv, one 32ld650 and one 42ld650, that I keep only because they are connected to the wireless dongle.

Both have the same issue, the power light blinks but won't start. I tried to reflow the main video processor several times on both tv with no success, every time I end heating it in the electric oven (pre-heated to 385F, 5min), and that fix last about a year.

I believe this is different of the no hdmi issue, and is not the bga solder of the video processor.
