The picture on my Advent TV HT2751A is curving inwards.
My 27" Advent TV HT2751A is having issues. We were watching it fine this morning, then we put in a DVD and the vertical edges are now concaving in. The left side is less prominent than the right, but both sides are definitely going. The effected area is just pure black. The picture in the center does not seem to be changed. We love this TV, and while it isn't a flat panel tv (it is a flat screen), it has MUCH better picture than any flat panel being sold out there. We would really love to save this television if possible.
I also have the exact same problem with my Advent HT2751A which only started recently, so it makes me wonder if we purchased our TV's around the same time (12/04). I don't know if it's related but my TV is also experiencing a problem where it needs to "warm up" for several minutes (perhaps as many as ten) before the picture comes in. For the first few second the TV goes through a series of flashing green lines all over the screen, then settles down into a blue screen until the picture flickers into view.
I would like to think the two problems are linked, but the warm up problem has been there for almost a year now, and the "inward curve" is a new problem.
I have this same problem. It is with anything you plug into it, including just plain cable. It is NOT from plugging things in wrong, because it does the same thing even if nothing is plugged into it wrong. Can someone help us please? I have this same problem.

I am having the same problem. This occured about 2 weeks ago. I have tried everything to correct the situation but it stays curved. I am using a DT converter box, vcr, cd player, and have used the s connector to connect to my laptop. This occured when I connected the laptop to it. I have connected my laptop to another tv with no problem. I have unplugged it for 24 hrs to allow total discharge of all electronics inside. Hoping to reset and reboot the tv. My wife is upset that it has happened and wants it fixed. (TV repair wants title to my right arm to repair it) HELP anyone with a solution. Thanks

This is not a solution, but a request for assistance as well. I could not find anywhere to post that I am having the same issue as the previous posts. We were watching tv this afternoon, and this evening we noticed the sides of the screen bending inwards. I am wondering if it is the picture tube that needs replacing or is it something simple. We did not plug anything into the tv for quite some time, so I know for a fact it is not the dvd player or the converter box. If someone may know of a solution that is not costly, could you please post it here?

You have a bad capacitor off the vertical output I.C..Find the pin off the I.C. that represents the out of the I.C. If you have a capacitor checker, you can check the ESR(equivalant series resistance) to see if it reads high.Look on the internet for a schematic,this will show which pin of the vertical I.C. is output,and the cap. that leads off it..
Hi, although I have all sony tvs in my house, every room brand new, when there broke there like a opened bottle of wine ,FLAT, no good!! A 27 is so cheap its worth buying a new one. UNLESS you live where you have friends that fix them on the side. I do and if you ever get to seethe inside of the tv you will wonder what your paying for there is only a few parts in them now and my friend chks them with a machine in 10 minutes if it is worth fixing he has the parts on the shelf and it must be under 100 or its going in the barrel. I have had 1 fixed 10 minutes still good other 1 he threw it out. That's all I can do for you from here, sorry, good luck, Frankie
I don't have schematics of this particular tv but I would try to help you to diagnose and rectify this problem. I think that your tv has problem of pin cushion, incorrect picture size at sides, this is cause of few defective parts in Pin Amp area. I need few clear and focused pictures of both sides of TV main board to see what part is damaged. Thank you.
After 3 years, I finally decided to open up the TV and do some troubleshooting. Found out the problem, It was a blown capacitor Location C554 Capacitor value is 2200uF 16V - costs about a dollar to replace yourself and the TV works brand new.
Have you had any kind of magnets close to the tv set? I had a brand new sanyo do the same thing. I had pulled the speaker box out of my truck and stood it up next to the tv (not thinking about where I put it). Turned it on a few hours later only to see a messed up picture. I moved the speaker box to get behind the tv and the picture got better. Moved the speaker box back to the truck and after a couple of days the picture was back to normal. These were 4 large magnets on these speakers. Maybe I helped some!
