SOURCE: Green Display Problem

Hello vinodquilon,

The problem you described is more then likely related to the video processor. Possibly also some power supply issue, since the audio section is being effected also. Or this may be two unrelated problems in that case the video processor and the audio processor and amplifier should be suspect. This is how I would handle this problem:

1) Get the schematic for this TV

2) Tackle the video problem first
a) Locate the video processor connect a known video source generator (I use the Sencore VA62A) and take voltage measurements and compare them to the schematic values (For red, green, and blue), if the values are not as they should be, use and oscilloscope to look at the waveforms of the video section and compare them to the schematic values if they are not as they should be, change out the video processor. Retest the TV, this should take care of the video problem.

3) Tackle the audio problem
a) Using the audio section on the VA62A inject a 1000Hz tone into the TV and using an oscilloscope check the input to the audio processor and the output of the audio processor if you do not see a 1KHz sine wave on the output check the voltage levels and compare them to the schematic, if they do nor match change out the processor, if they do match and you see a 1KHz sine wave at the output of the processor, then check the input and output of the audio amplifier stage in the TV if there is no audio at the output change out the amplifier.

This is a good starting point, now I must be frank with you, I run a TV repair business and I do understand that you may not have , Video Signal Analyzer or Oscilloscope, and Video/Audio Signal generator, or even a multimeter to do this job correctly, so since I have told you how I would do this job and you can follow the instructions given and solve your problem, Let me advise you on what you should do,

If I were you and did not have the above equipment nor experience in electronics, I would take the TV to a qualified TV repair center and have it fixed there since they would have the necessary equipment to do the job properly.

I hope this helps,

Thank you,

SOURCE: I have a Xerox Phaser

What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem.
You can try googling. Phaser printer print heads or phaser printheads.
There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head.
Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads.
Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP.
The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.

I have a new heater with diferant terminals from the old one so not sure how to atach the wires


There is no need to rewire the internal of the heater!
Just bring in the electrical supply to the heater, it can be either 120 or 240 volts.
If the heater you have is like the picture associated with your post, then all then have to do is change the supplied plug from 240 to 120. It comes pre set for 240. That plug is inside the cabinet.

If any other brand, then you need to change the wires at the transformer of the heater. All heaters need to be supplied with primary voltage: 120 or 240. Then the control system is supplied with secondary voltage out of the transformer. The secondary voltage is no more than 28 volts. and these wires are normally colored as blue or yellow.

Secondary power is already wired within the heater. NO need to change where they are. You will only need to deal with the Primary wiring.

There are many varieties of transformers that transform high primary voltage to a low secondary voltage of 28 volts. and these transformers have many wires: primary & secondary.
I will try to make this easy to understand.

If you have a Gas Heater Transformer with these colors:
  • Red
  • Black
  • White
  • Green
Or...
  • Red
  • White with Red Stripe
  • Black
  • White with Black Stripe
  • Green
These are Dual Voltage Transformers, you can bring in either 120 Volts or 240 Volts

If you bring in only 120 Volts...
1st example:
The Red wire will not be used! Hot wire to the Black, and the Neutral/Common, to the white wire. Green to ground.

2nd example:
Connect the Red wire with the White with Red Stripe together and connect these to the incoming Neutral/Common wire, normally White.
Connect the Black Wire with the White with Black Stripe to your incoming Hot Wire, which is normally Black.
Green to ground

If you bring in 240 Volts...
1st example.
1 Hot wire to the Red, the Other Hot wire to the Black, and White wire is not used. Green to ground

2nd Example:
Wire nut the two Striped wires together. then one incoming Hot wire to the Black, the other incoming Hot wire to Red.
Green to ground

Or This is only a Low voltage - 120 Volts Only
  • Black
  • White
  • Green
Or either any of these combinations...
  • 2 Blacks w/Green
  • 2 Reds w/Green
  • 1 Black, 1 Red w/green
This type will only be a high voltage, 240 volts only
Picture below is what a transformer looks like and it is where your incoming supply wires go. The smaller leads with the spade connections will go to a specific location & is the 'Secondary" .

Good Luck

My onida 21" black color


Possible there is a fault in soldering. Poor joints in the CRT base circuit of the CRT tube will result in poor connection after some use due to the fact the heating and cooling will detach off the leads. So use a good soldering iron to touch up all the points in your main board and the CRT board and it must work provided your tube is not faulty.

What is the secondary voltage of power transformer


The schematics do not show the actual voltage.

From the design, the phantom power secpndary should be around 35 to 45 volts AC.

The 16 volt supplies would require a secondary winding that will be around 26 to 32 volts center tapped.

Transformers are quite reliable and unless a voltage is missing, the transformer is likely OK.

The most suspect items are the electrolytic filter caps if the voltage is not the design 16 plus and minus values.

2001 Ford E-150, year 2001, wire harness connection


As for the head units leads they should be marked or identified in the installation manual. There are but only three wires here that I might be able to help you with.
Two of the wires should have in-line fuse links (12+ volt power) and they are the constant feed (for memory) and the switched feed (for operation). The ground lead is typically solid black.

This is a general factory radio color code. Wire colors in your car might be different than colors described here. Use the given colors for reference purposes only. Always test wires to make sure they are correct.

Good luck

It could actually be quite a few things, loose wire, loose solder piece, bad crt's/picture tube, bad system board, or others. It's would have to be diagnosed with testing equipment. It will probably cost you another 150-200 for the new part to be put in.

try this

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
