Hi,

Below are some troubleshooting tips for a TV that has a fuzzy or blurry picture;

If your Plasma or LCD TV picture is blurry or fuzzy there are several things that may be causing the problem. It's worth running through the following list before seeking service. You may find yourself saving the full cost of a TV repair.

Make sure you are using the appropriate cable box for your TV. If you have a high-definition TV you should also be using a high-def channel box from your cable provider. Watching standard definition channels on a high-def TV can make the picture look distorted and fuzzy.

Not all cable channels are broadcast in high-definition. When you stretch a standard definition picture to fill the full frame of your wide-screen TV it may look distorted. You can try changing your TV display settings to show standard-def channels at their native resolution. This will create black or gray bands on either side of your picture.

Ideally all of your video components will be connected to your TV with HDMI cables. Your next best option will be component video cables. If your cable box does not have HDMI capabilities, contact your cable company about upgrading your box to one that does include HDMI.

Make sure there is no glare on your TV from a window or other strong light source. This can significantly degrade the quality of the image you are watching.

If your TV has digital noise reduction, try turning that feature on.

You can adjust your TV's sharpness and picture modes to see if that improves picture quality.

Try plugging the power cord into a different electrical outlet and/or surge protector. You may be receiving electrical interference through your power cord.

Trying moving any nearby electrical devices away from the TV. They may be creating interference that can degrade the picture quality.

Let me know if the above helps or not, so that I can direct you further on what do next.....

Best regards.

There are fuses in the back of your tv that may also have blown. Ckeck them if you can. There are other things that can cause this problem as well.

I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.

High Definition Projection TV


The flashes are a diagnostic. It should be only one flash pattern, either a 5 or a 10 (there are several other patterns in between as well). Please verify the number of flashes after power on, several times, and post back here, and I will be able to help with the fix. Based on your initial description, it my be the HV distribution.

Hewitt Packard high definition DLP tv Product #EX543AA#ABA need part, hp no longer carries them.


I have a brand new L2114a lamp for sale. I paid 299 plus shipping on ebay but it turned out to be the wrong one (despite what the manual says). I ordered the correct one I needed from HP. I am willing to part with it for 200. I can send pictures of the lamp and the box and the reciept. This is a BRAND NEW LAMP.

This lamp works in the following televisions and replaces the lamps listed below:

Sony KP-57HW40 tv is what we have now and is this a high definition tv?


After the FEB 2009 cut over, your "OLD" tv will nolonger be able to receive OFF THE AIR signals as they will be broadcast over different frequencies. HOWEVER, as long as you subscribe to CABLE or SAT TV (Dish/Directv/etc) your old TVs will continue to work as they always have -- (because the signal is not OFF AIR) but you just won't have an HD picture.

Phillips 60'' projection hdtv wont turn on


Question do you see green led or light when pressing power button? If you can also listen for a high pitch noise coming from back of set. This would be an indication that the set has powersuppy problem or high voltage problems. If the set is dead and no noise then maybe fuse or open circuit.
