Something coming in on cable or antenna mode--could be a tuner bad but more likely a bad connection or a loose one on cable wires.

In many cases it is possible with a box to go audio/video from box to one of the rear inputs and bypass the issue.

SOURCE: height is small in aiwa

this is the conversion chip and vertical deflection chip that need to be replaced
service mode will only make the color alignment worse since the conversion chip is failing so it won't align properly
it will need that repair

SOURCE: Blue lines that surround a face or broken lines across the screen

Your TV most likely has one of two possible problems.

Problem #1 - Failure in the convergence circuits. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Hi,
If this is a rear projection set you needs the convergence IC replaced,
the model # wd52725 indicates it may be a DLP (probably not correct). If its a DLP the problem is within the power supply or video/formatter boards. The convergence ICs should cost between $250 and $400 to have a servicer install them depending on their labor rates.
If this is a DLP model the power supply repair (just capacitors) would cost the same, but if the boards are bad it would be over $500 to have repaired.
Is it worth the repair? Most servicers charge an estimate fee $60-$120
perhaps for can ask them for their labor rates for the IC install instead of having them drive out and tell in person what they could say over the phone.
Compare the repair prices with the replacement price and decide based on, your budget, how old the set is, what you paid for it originally.
You can buy a new 52" proj set for around $1000-1200 DLP or LCD
you will get a 1 year warranty on a new set, but only a 90 warranty on the ICs. If you buy a new set try to buy the 3 or 5 year extended warranty to protect your investment.
hope this helps

Check all the coax cable fittings by moving each with set on---you are looking for a loose shield connection (outer one to connections) that can with ease cause this problem.

Can't get closed captioning to work on westinghouse 46" 4680 led tv


What is the video source? Some set-top boxes send a closed caption signal that doesn't match the TV's CC interpreter. For those devices, you need to enable the captions on the set-top box.

I know how to enable captions on one particular Dish satellite box. The steps will depend on if your TV is TV1 or TV2 connected to the box. If the TV is TV2, you need to set the box in Single mode (so both TVs are set to the same channel). This is done with the Mode button on the box itself (highlight Yes and click Select using the Dish remote when prompted to go to Single Mode). If the box is in Single Mode, you won't get a prompt but the unit will go to Dual mode. There is a small LED on the box to indicate Single or Dual mode.

Next press Menu on the remote and go to Properties (9). Click Select and then navigate to Closed Captions (6). Click Select. Go to the Closed Caption On/Off line (1) and press the left arrow and then the up/down arrow to set to the captions to On. Press the right arrow and then Select with Done highlighted. Exit the Menu by hitting Cancel repeatedly.

I hope this helps.

My kicker kx 1200.1 keep clicking to protection mode back and forth when it power. There is a clicking sound comming from the amp...is it a major problem to fix? This just start happening when i was listen...


Look for a frayed speaker wires. Look everywhere. Start where you can see and then look under carpet, under seats, trunk and everywhere wires go throgh a hole in steel frame. Any minor connection between the two speaker wires will cause high-power systems to go into protection mode. Wires can be damaged by long-term vibrations of your car, people stepping on badly placed wires under carpet, moving seats (when adjusted) or even rodents bitting on the wiring. Look closely and you will normally find it. Also look closely where you connect your speaker wires to the amp. One small strand of wire jumping across to another terminal will cause a short and cause protection mode.

No Picture or audio...NOTHING!!!!


You must use the remote to toggle the player OUT of HDMI output mode to use the s-video output. The device displays black screen by default, so not possible to see the menu if using s-video. The manual states to press the 'Progressive' button to change modes. Unfortunately, you can't see what mode you're toggling through until you hit the right one (Toshiba blew it here!!). Power on the device WITHOUT a disk in (you can't change modes during DVD playback mode). There are four output modes, so press the 'Progressive' button on the remote and wait for 3 to 5 seconds for the player to switch output modes. Repeat this up to four times to cycle through the available modes. During one of the modes, you should see output to your screen through the cable hookup you've physically attached. You will also notice the led's on the front panel go on and off during the process at times. Good luck ~ and don't bother calling Toshiba support ... friggin waste of time talking to a recording that's dumber than Sh#@!!
