I had a Philips 55" 4x3 HDTV that had a great picture and worked wonderfully but the allure of a LCD HDTV got to me and it's ease of use for my HTPC really helped. So I sold off my RPTV to someone who came and picked it up yesterday.
Well after they got it home and set it up it worked fine for a little while then (without me knowing what happened) the convergence went waaay off and the green is the worst of the three.
When looking at the grid the green is fine from left to right, but from the top it is bowed downward, and form the bottom it is bowed upward. I came over today to take a look and really coudl not beleive how horrible it looked. I tried to do the service mode adjustment to it but it would not let me adjust the green up and down, only side to side.
I played around for a while and eventually tried swapping the blue and the green on the digital convergence board and when I did this the bowing on the green was gone but the blue was now bowed. That leads me to believe it is indeed in the convergence board.... of course I am not a technician, just technically inclined

The TV from what I remember is actually a rebadged hitatchi. The convergence procedure is a painful one. Here is a page that lists the info:

now the Convergence board I am speaking of has the follwoing on it:
DP1X Convergence PCB
jk07132a
Pp15/16
There are two ICs on this board that supposedly do tend to need to be replaced after time and maybe this is just a coincidence that the traveling was all it took to finally kill them. I'll have to get those IC numbers and post them here later.
Anyway, is there anyone that has experience with this model TV or similar problem that happened to them in the past? Any help would greatly be appreciated (from both the seller and the buyer lmao) as this set really still did look excellent!
