Recently I have been noticing vertical lines/interference when viewing a mostly white screen while on full brightness. Is this a sign my epic needs a visit to the repair shop?

I have the same issue, it happens a lot when I'm using the browser.
Sounds like screen burn in, a fairly well known issue.
Is that covered by the warranty cause the screen gets super hot as well I can't imagine what its doing to my battery life

If it was screen burn in you would get those lines all the time.

Its the only problem with Super AMOLED screens, and what is fixed in Super AMOLED Plus.
Sent from my Epic 4g thats perfect in stock form.
That's odd I don't remember it ever happening before recently oh well its still bright as hell on low anyways but it will suck outside as that's the only time I up my brightness I wonder if its a power issue with the cpu as it only happens most during processing market or web pages

This is an engineering flaw. When the voltage from the battery drops, when it is not fully charged, and the screen brightness is at maximum, and the screen has a lot of white pixels drawing power, the display controller loses power, and has trouble with sync.
The battery will also drain slowly, when the brightness is set at max, even when plugged in and supposedly charging. This is even more critical on USB charging.
These problems are hidden most of the time, with the Display/Power saving mode, and dimmer screen settings.
It seems the full brightness is not properly designed and powered, and this is a shame, because it really makes the Epic 4G's display stand out.

Lol! I just had this problem crop up on me today for the first time, and I thanked this guy because he described it exactly, low battery and all, but it was his one and only post from a year ago. Well, still, thanks. I hope you read this someday.

Ok so I'm running cyanogen mod nightlies(September update) coupled with tiamat 4.0.7 + SBC. My battery regularly overheard while charging or when my screen stays on or using certain apps suck as angry birds, music, gameboid, snesoid, etc. Any ideas why it may be doing this and how it could be fixed? I've also run the cyanogen kernel and the regular 4.0.7 tiamat kernel. I've run decks roms, synergy equipped with the freedom kernels, and salvage-mod. Every configuration I use, I have the same problem. My battery hasn't been exposed to the extreme heat of the summer and its always charging in a cool place. I'm using the original HTC charger that came with the phone. Help would definitely be appreciated because its killing my battery. Thanks guys.

Are you overclocked?
Nope underclocked. Running smart-ass settings underclocked to 128 and Max is 768. Still hasn't solved the problem.

So it does it, even when it's not on the charger?
You may have a bad battery or a malfunctioning phone.
It does this all the time. Right now spare parts says its at 43.8°C but before i plugged it up i left it off for 20 mins and turned it on and it was at the regular 36°C. I'm hoping its not the phone. And this was a replacement battery I received from the sprint store after my last battery drained within 2 hrs on a daily basis. I've tried calibration and it doesn't help. Battery life is slowly degrading as well.

SBC kernels may overheat your phone.
Try a diffrent no-sbc kernel.

Try returning the phone to complete stock.
If it continues to do it then you're gonna have to take it in.

Well only problem with that is the fact that it did the same thing stock I got my replacement battery before I ever rooted my phone. So ill revert to stock and take it in for them to run a diagnostics test on it. Just gotta find the right location.

Well it sounds like either the replacement battery is bad, the charger is bad [causing the battery to be bad] or the phone itself has a problem.
Could be the charger. Half the time it registers as a USB charger but its the AC outlet charger and when it does switch over to AC it becomes even more prone to overheating. I know that when the battery overheats it can cause internal damage to the phone if it gets hot enough. Hope it hasn't done that yet.

I've had a G2 for a couple of years now that hasn't been working. I've exchanged batteries, but cannot get anything to boot. The phone was having problems with freezing prior to the supposed brick, and the phone is completely stock.
As of now, I have it plugged in via USB and I didn't hear any sort of notification that the computer even recognizes the phone, my other android phones will get picked up with the power off.
Long story short, is there a way to get into "upgrade mode", or something similar that HTC might have? Something from ADB that could trigger the phone to power on in the hardware doesn't power on itself?
Thanks.
EDIT: The charge LED does NOT come on while plugged on to the charger.
well before i say no can you get a battery that you know works and try this first

Stupid thing has water damage..the VOID sticker wasn't where it was supposed to be, but I saw some pink residue from the sticker. I'm gonna take it to see if I can get it fixed. I believe it's worth it, it isn't the first batch of G2's, it was one of the warranty replacements that didn't have those weird issues.
Take a multi meter to the contacts with the phone open. See if any power is getting through.
In ICS it lit up pretty good and now its kinda dim, what gives? Is this normal ? How can I make it brighter again?

Mine is also dimmer than it was on ICS. After the OTA update I noticed it. Did factory reset with same results. Formatted everything and applied the rooted version through odin and still have them dimmed LED. Updated my brothers S3 and his is the exact same. I got a text message last night and the LED was fully illuminated, but after I opened it and received another message after it was dim again.
This needs to be fixed I'm very ocd about stuff and this is fine of em

I always thought they needed more power? but they are more efficient as using this power?? I dont remember its been forever since ive studied electronics
Anywasy, on topic, i run CM10 and dont think its all that dim. Maybe they added an option inside the settings for brightness? I wish it had the "breathing" option instead of just flashiing. But check for a setting maybe?

Not really positive about details. I think they are more efficient. Whether they use more power I have no idea. I know our utilities company is offering to take old Christmas lights and they give you LED strands instead for free.

Single color LEDs are quite efficient. These multi-color, variable brightness LEDs are somewhat less so. That doesn't really matter the question at hand though because most of the power drain of LEDs is just having them on. The difference in power drain from a low intensity to a high intensity is marginal.
Anyone know what could be causing my phone to just shut off randomly. It's been doing it heavily the past few days.

Of course it does! The rom, the kernel, any tweak apps your running, regular apps... Lots of things can be responsible. Since no one here has your device in their hand it's very difficult to assist you without you providing as much information as possible. Your asking for help, you have a problem not the ones trying to help you. So do yourself a favor and give the information requested, unless you like your phone re booting constantly.

How is it shutting off, does it vibrate when shutting off or just straight to black, like you just pulled battery. If it vibrates as it powers down, likely a rom and/or kernel related issue, if it's just straight to black like you pulled the battery, likely a battery, battery pins or a failing power control module.
