Question about Televison & Video

Constant sound static and picture jumps

I removed the back cover and carefully vacummed as much dust off as I could, as suggested may be the problem. This made no difference. Is there something else I can do myself/

You don't mention the model, but your symptom is common for many brands of TV. Solder connections inside the tuner go bad and cause the kind of problem you are having.

When the trouble starts, try tapping on the back of the set where the antenna or cable connection is screwed on. You may find this causes it to clear up or at least have some effect. If so, the problem most likely would be cured by repairing the tuner. This involves taking the tuner off the circuit board, opening its cover, and resoldering the connections that are usually visibly cracked.

This is probably not a repair you could make yourself, unless you have some experience with electronic soldering. But a service call would be less than the cost of a new TV. If you decide to go with a service call, make sure to tell the servicer you'd like the tuner repaired. Some techs will just give an estimate for replacing the tuner because of time, but opening and repairing the tuner does not take that much longer than just replacing it. And it saves you the cost of an expensive part.

How to open up to chick the hard drive


Before you start, be aware that minute traces of static electricity can destroy a hard drive. If possible, wear an anti-static wrist or foot strap; at the very least, do not work on a carpeted floor, bed, or while wearing static-producing clothing (like fleece). Work on a non-conductive (wood, glass) table grounded to a non-conductive floor (wood, linoleum, tile). Wear latex or anti-static gloves and turn off fans and close windows to avoid dust damage.
1. If you haven't already, back up your data on an external drive. 2. Shut down the computer and unplug the power cord from the computer. Remove the battery. 3. Close the laptop and set it screen-side down on an even surface, with the hinges facing away from you. It should look like this:
grtartst.jpg
4. The component labeled "7" in the above picture is your hard drive. With a small Phillips head screwdriver, carefully remove the screws on this outer casing only. Set them aside and remove the hard drive cover. 5. Your hard drive will be screwed in by one to four screws, depending on assembly. Gently unscrew these, being careful not to apply too much pressure to the very delicate top and bottom of the drive. Handle by the sides only. 6.There are connecting pins on one side of the hard drive. Identify these and gently pull the hard drive out from this side, not forcing if there's any resistance. 7. Depending on your problem, you may need to remove the silver enclosure to the hard drive. With the appropriate Phillips head screwdriver, unscrew the screws and set them aside, carefully sliding the enclosure off of the hard drive. At this point, your hard drive is extremely susceptible to shock, electric shock, dust, and simple trauma. Be careful.

What is the best way to clean out dust out of my ony CDPCX455 400 Disc MegaStorage CD Changer by Sony


carefully remove the cover/top of the amp, usually held on by several screws on the 2 sides, and possibly a screw(s) on the back, towards the top. use a can of compressed air to blow the dust up and out. do not use a floor or shop vacuum under any circumstances, because it may produce static electricity and damage the electronics.

i am not responsible if removing the cover alone voids your warranty, but as long as you use only compressed air and DO NOT touch anything inside the changer, nothing will be damaged. again, do not use a vacuum, unless it is especially designed for anti-static electronics use.

Red light is on but the tv wont work


Unplug tv, open the back and vacuum all dust that you can see... also remove the power supply board and brush/vacuum the back side. Hold any metal part while you're vacumming to eliminate the effect of static electricity. Good luck.

Fan very loud all the time


probably easiest if you take the back cover off your laptop, and remove the fan completely. then remove your fan. clean all the dust from this, and also clean any air vents. obove the fan should be a metal grid thing. clean all the dust from this! this is the heatsink. usually you should use a can of compressed air. but i use a vaccum cleaner - USE VACUM CLEANER AT YOUR OWN RISK. IT CAN CAUSE STATIC ELECTRICITY DAMAGE.

Picture jumping


If this jumping is accompanied by a sharp snapping sound, it may be the high voltage circuit discharging to chassis. Leakage can cause the jumping and a discharge can momentarily blank the picture.

If you want to try a 'cleaning cure,' I suggest you pull the plug (not just turn it off) for several hours, preferably overnight. Sets of this size can carry enough static charge to punch a hole through your thumb if you get careless.
Remove the rear housing (shouldn't be more than 6-8 screws) and using a clean paintbrush, and possibly a vacuum to **** up the dust, clean it well and pay special attention to the area around a largish misshapen black plastic object bigger than most anything else and connected to the back of the picture tube via a fairly thick cable.

Picture bounce or flutter


In case there is a loose connection and the convergence board is not damaged. This is what I did and worked out "perfect".
My Mitsubishi HDTV Medallion 1080 has been with us for about 7 years.
The TV started showing distortioned colors and images and even when I used the convergence options from the main menu, it would not show clear images until it would be working for around an hour or if we would hit it until the image would fix. It got worst over the time at a point that it would require 2-3 hours working and several punches and kicks.
No doubt dust has done it's job, well, a vacum with a brush end can help resolve the problem.
1. Make sure the TV is off and disconnected from power.
2. Remove the rear cover at the back (it is clear wood colored and is at the lower part of the cabinet)
3. Using a vacum with a brush end, vacum all the dust that you will find. Be cautious not to hit the components and do not or apply preassure while doing the work
4. On the left side, you will see a card over a mother board, make sure to vacum it well and that it is well inserted in the slot (I did apply some preassure to make sure it was fully inserted)
It took me around 15 minutes and my tv is working like NEW.
While you are removing the dust with the vacum, you may want to vacum the 3 lenses as well, again, using the vacum, no need to clean them with a cloth. I saw a thick layer of dust over them and could remove it easily with the vacum.
Hope this will work for you.

Picture & Sound blink off 45 seconds, blink back on, repeats


If the lamp is foggy then you really need to replace it. The lamp life is typically 5 to 7 thousand hours. However if your tv gets a lot of dust inside which is pretty normal as most people don't vacuum the dust off from the rear cover on a regular basis then the lamp life will be drastically reduced. I suggest you replace the lamp and make sure the inside of the tv gets vacummed out to remove as much dust as possible. A Sony servicer should be able to check the amount of hours on your lamp. You'd be suprised how soon 5-7 thousand hours happens. If the lamp will not come on after replacing it the lamp driver may be at fault. You haven't said how may times it's blinking. If it's 5 then the lamp driver may be at fault.

On and off picture and color weak Sanyo HT30744


I had the same problem with my refurbished HT-30744 model and my mom's HT-32744 model. It was either try to fix it or buy a new one, so I figred had nothing to lose.

I removed the back cover, unseated the picture tube driver board from the neck of the picture tube (it just pulls off), put on a dab of di-electric grease on the connector on the card, reseated the card, removed and re-applied more grease, reseated the card and the picture has like new for 2 weeks now!

This was a very easy fix.
