Re: LG lg52lb5d HDTV picture problem

Ill check the model of my dmm when i get to work. I have a dc clamp i just need it mailed to me.

Anything else i should check while i have it open?

I plan to replace the known bad capcitors and check power supply voltages.

Re: LG lg52lb5d HDTV picture problem

Its a fluke multimeter when i went was measuring current on a alternator i went over the limit of the fuse, it will not read anything now. I will try again.

Thanks for all the input so far! I really appreciate it!

Here is an updated photo of the picture appears to be getting worse....

Re: LG lg52lb5d HDTV picture problem

I looked up the internals of a generic lg tv, it appears i would be talking about the powersupply. So that could cause picture problems eh? I may have to order some caps here for it. Are you able to see the problem with the pictures i posted, i thought it might be kind of hard to tell what exactly im talking about, its almost like a cloud over it. But very distorted colors also.

Re: LG lg52lb5d HDTV picture problem

Sorry I am new to tv repair. I have been repairing computers for awhile so i thought i would give tv's a shot. Is the main board the board with the all the inputs(a/v inputs)? Because the board I have found bad caps on had no inputs and its large next to the one with the inputs, i cannot put pics up tonight, because i needed to reassemble it to move it.

I have had this tv for about a year now, and during my last deployment my wife said it started having problems with the picture, the colors are very distorted, with no visible lines or anything. Well about two days after she told me it corrected itself. It did this two more times, well now it has done it again, and it wont fix itself. I opened the set up and noticed there are two or three blown caps on the main board, but would that cause picture issues? I thought that would cause power issues?

I have attached two pictures that kind of capture the visual problems.
Thanks...
