Question about Philips 37PF7320A 37 in. HD-Ready LCD Television

1 Answer

TV loses video and sound

Your description of this problem to another poster describes my issue exactly and I described this to the Philips Customer Service support folks even describing what I thought to be a heat problem, they offered no assistance. Questions - 1) is this a fairly easy fix, I have some technical experience with electronics?; 2) do you know where I can get a service manual to help with this fix?; 3) where can I purchase these parts?

Thanks

Check the firmware on the set and if is is not BX23U-1.5.0.0_03531 go to www.usasupport.com to down load the currect version. That should fix the problem. If it does not your small signal board need to be replace.

What part i.e sound card, circuit board would I need to fix the sound on a Philips plasma tv model #42pf7320a/37?


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Sound goes up and down - when its at a low point I can here a voice describing the actors movements as though it were a description for the blind - can this be deactivated?


Look in your TV menu for a 'Descriptive Video' feature, and disable that feature.
Does this happen on all video or specific input? (ie. DVD, Cable TV, BlueRay, etc.)

How do I get rid of the voice over on some programmes on my LG 47LF6 model tv?


It sounds like you are talking about "described video". Does your signal come through a set top box before going the TV or is the cable hooked directly with the TV? If going through a set top box first, you need to change the setting in the set top box.

I have a Philips plasma 42 with black lines across the screen


I would first check if there is an available firmware upgrade for your model .Upgrade requires you to download firmware from philips website.Then transfer it to a memory stick .Then use a memory stick reader to plug into tv for firmware upgrade.Other wise the set would probably need repair .Possible a bad SSB board or another issue

I have what can only be described as a stain on the screen of my 32 inch lcd phillips. its only on part of it from the top mid half way down ,looks like a water mark.


I assume this stain is internal? From your description it sounds like a flaw or fault within the screen. The only solution would be to replace the screen

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. The TV should have at least a one year warranty from Philips. If you're out of warranty and didn't purchase an extended warranty plan, you'll have to pay for the repair yourself. The cost will likely be in excess of $300 and could exceed $600 depending on the exact cost of the circuit board needed to complete the repair. If you're in warranty, call the number in the back of your manual and they'll set you up for service. They will likely request a copy of the receipt to validate the purchase date.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. I hope this solution has earned a positive rating.

Please let me know if I can be of further assistance.

Sounds like you need to repair the power supply, don't fret, it can be really easy.  Here is a pair of youtube videos I made after following some advice on this website from other posters:

Hi, can you see the menus etc?

If not, then I had a similar problem that I posted. I recently got an engineer to look at my TV and they had to replace the main circuit board.

Once they replaced it, everything was fine again, but unfortunately the part alone cost me around £250 ($500) and then there were labour charges on top of this.

LG parts are very expensive apparently.

I'm no expert, but your problem sounds exactly the same as mine. Maybe try describing further - read my post here:
