Question about Philips 30PW8420 TV

1 Answer

Tv won't turn on

So i've had a 30PW8420 tv for almost a year. I recently discovered a nifty little menu called "SAC" i believe (you access it by pressing 062596 and the menu button, and then holding down the Volume - and Channel - buttons)

This menu included many tings, but the msot important thing for me was the "Geometry" section, because the vertical and horizontal settings on the set were a little screwed up.

Anyways, the problem is i may have accidentally hit the wrong button at the wrong time. I was crolling through the menu, and i saw something that said like "activate SAMC mode" or along those lines. I did, and the tv shut itself off afterwards. i don't remember if those were the exact letters, but i'm 100% sure there was 4 letters. Now when i try to turn it on, i "hear" the sound of the tv powering on, and teh LED turning on, but then it shuts itselff off before the picture or sound comes.

Also, something interesting. I can turn it on by pressing the volume and channel buttons on the set itself. Weird, huh?

    Yeah, i got it fixed. I left it unplugged for 24 horus, plugged it back in, and it worked.

    Lesson learned: don't mess with the Service Menu :)

    I'm having a similar issue with mine actually. I was fooling around in the service menu and trying to fix the geometry. I adjusted the trapezoid option a bit too far and the screen went off. If I turn it back on, the LED stays solid for about 3 seconds, then blinks 3 times and the TV turns off. I know it's an error code, but how certain is the unplug option for a reset? I've heard it can be either 4 hours, or 24 hours, so I'm a little unsure.

    Another question I meant to ask and perhaps more importantly.
    Did you manage to get your vertical and horizontal problems fixed using the service mode?
    I have some concave issues with my 4:3 screen and there's nothing in the user menus to correct that.

How to reset access code on magnavox 20ms233s

Hi. It's really necessary to have the original remote. All so called replacment do not have the "menu" button. In Philips TV's access code is not rquired. In your case, some channels are "whiped" and cannot be recalled. If you can go into setup-menu, things can be rearranged. There are numerous web-shops where you can buy an orignal remote. I recently bought an original remote for my DVD player. This however was at an on-line shop in Belgium. Just surch for Pilips on line shops in your country. Good luck.

TV turned off by itself and now won't restart. Blinks three times pause and then eleven.

Google your make and model with the words blink codes at the end. This will take you to sites where you can look up your blink code to find out what is wrong with your set.

Philips tv powered off and wont turn back on

There is a smt located at 7404 [C-6 Bottom] A common problem, does the tv make a sound like it wants to come on? Location 3239 should be small resistor, 3414 another resistor and a driver transformer at 5402 if it looks burned. See MCM electronics website and see if there is a kit to repair this. Or ask for part #s as per location of problem area mentioned. What you will be doing is changing the timing so all the components will come on at the same time. If this is done correctly you will notice the top of tv screen will flash red, green and blue lines. This will be the new norm each time you turn it on. But it will be OK. This is what the flashing green light is telling you. signed the Green Lantern7!!!!!!!

Philips 30PW8420/37 TV Won't Turn On

The led code indicates vert failure for one. ( 3 blinks )
The 2 blinks indicates excess beam current of which could be your picture tube or re-adjusting the G2 voltage on the HV transformer which is very critical on philips sets.
