Fuzzy is a funny word. I never use it to describe a picture problem. That because fuzzy can go too many different ways. There is snowy fuzzy, blurry fuzzy, grainy fuzzy, and demodulated fuzzy. If the set goes out of focus intermittently that has something to do with the focus ciruitry. If it goes grainy that is a front end problem, usually tuner related. The other types of fuzzy are generally associated with problems in video processing some where. So, which is it?

Oh, and BTW that unit has three small picture tubes in it, one red, one blue, and one green. It doesn't have a 'bulb'.

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.

Philips 46 in rear projection tv has too much green. The bulbs are good but adjusting the color does not help.


this models have coolent issues. I would tke off the front screen very carefully , as it may seperate , get a friend . Do not scrach the screen. then look down inside the units CRT's (Cathode Ray Tube) and see if its cloudy or fuzzy looking . While there look at the blue tube as well. If its fuzzy replace the coolent.

Mitsubishi 65in DLP TV picture is not clear after I replaced the bulb. It was clear before the bulb was replaced but it seems to take time to catch up and is a little fuzzy.


Sometimes dust can get in between the lamp and lens take lamp out and check for dust with a lint free cloth.
If thats not it it could be the manufacturer of the lamp. I usually try to get the same manufacturer. You can try tinkering with sharpness or contrast but remember the points you adjust from just in case it makes it worst.
Good luck

Blurry/Fuzzy Picture/Double Vision after power outage


Hello stevenkgray and ADIMEN,

I think what has happened is the your TVs are out of focus which could be due to a voltage problem. First I would warn you that this is a problem in the High voltage section of your TV and caution should be taken, in fact I would suggest that if you do not have a background in electronics that you get the TV checked and fix by a qualified TV repair technician. However if you do have a background the next few lines will make sense and you might be able to effect these repairs yourself.

Items needed for troubleshooting:

Schematic Diagram
Multimeter
High Voltage probe (40Kv)
Universal Video Analyzer (UVA)

1) Unplug the TV and take the back off of it

2) connect the UVA to the tuner F connector and setup the UVA to send a test pattern into the TV

3) Power the TV back up and turn to the channel set on the UVA

4) check the anode voltage on the CRT with the HV probe (connected to the Multimeter set to volts and grounded) and compare it to the voltage on the schematic.

5) If the voltage is not right adjust the focus and screen controls on the Integrated High Voltage Transformer (IHVT) to obtain the proper voltage.

6) Check the pattern to see if it is still fuzzy.

If the pattern is still fuzzy you may have to inspect/replace the IHVT and or its associative circuitry.

If you suspect that the IHVT is bad you can perform a ring test on the transformer using the UVA. (The instructions on how to do this are on the UVA quick steps pull out. or the instructions can be looked up on the web.

I hope this helps

Thank you,

Color & sharpness problem


Sounds like you need Coolant fluid change, this is the fluid under the Lenses. If you have not done this before I suggest that you get some one who is qualified. Because if the coolant leaks and get to the circuit board, there goes your tv. You need new fluid in the 3 CRT's. If you look down with the back off and looking in the lense, you would see contamination in the fluid, this needs to be taken out and cleaned and replaced with new fluid. The fluid can come from places like MCM electronics corp.
