Blooming causes bad focus!

My flyback burned and I replaced it, but now I am having a major problem with blooming! Whenever the picture is bright, it enlarges, and when it becomes dark, it shrinks alot. This is causing it to go way out of focus, and if I focus it when it is bright, it is out of focus when dark and bleeds alot and vice versa. How do i fix this? Is it possible?

This load-related change is caused by the failure of the power supply to keep the service voltage for the high voltage section regulated.
The flyback may not have been the only component that failed; its failure may have damaged components in the power supply itself.

What makes Whites appear so bright almost blooming that hurt the eyes


In the model listed here having contrast way too high can cause that--contrast should not exceed 70 percent and brightness should be a bit lower or equal--note as contrast is lowered the white smearing should lessen.

I have a tube tv. the picture as lines and is blur that goes in and out.


If the lines are colored DIAGONAL lines, they are referred to as "retrace lines," which indicates either that the picture tube bias is set too high, or the brightness level is set too high.. If the blur occurs when the image is particularly bright or a particular color is bright, it is referred to as "blooming." This is caused by either a weak high voltage circuit or because the picture tube bias is set too high.

Is the picture set very bright? Try reducing the brightness control to a level where the retrace lines disappear, and reducing the contrast control below the level where the blooming occurs.

If the television is more than ten years old or has many hours of use, the picture tube may simply be deteriorating normally. By nature, they have a limited life span. Before you decide to throw the set out, if you are technically-inclined, try adjusting the bias and screen drive controls for the television as recommended by the set manufacturer (you didn't specify what make or model the set is), and you may get a few months or years of additional life out of the set.

HATACHI IS OUT OF FOCUS


This can be a number for things. Believe it or not dust or cig smoke in LCD and pix tube projected TVs turns up looking a lot like focus error. Is the focus bad or do you have a convergence error (red, blue or green shading) Is there any smearing or blooming to the pix? The other comment for you is the TV is 9 years old I personally consider this very close to the life of the product. A simple good pix would tell volumns for someone like me (may need some resolution on the pix).

Contrast blooming/breathing. R-G-B bias and drive pot values


If the picture is only bending in on the sides the problem is in the pincushion circuit. If it is the entire picture there is a voltage regulation problem either in the power supply circuit or the power supply off the flyback transformer which is usually a diode and capacitor combination. If you want to go with the odds, replace CR4118 with part number 164590. You may want to put the original flyback in as there are many problems with aftermarkets and even if it is an RCA part it is still aftermatket. As far as the bias pots a little cleaning spray usually does the trick. I wouldn't worry about trying to get a perfect grey scale out of a 16 year old tube, the original pots are plenty accurate.

Picture to wide


This trouble symptom picture wide or"blooming", the picture becomes dim even with the brightness control full on,and there is an abnormal enlargement of picture or raster.Usually,the enlargement is uniform,but there may be some defocusing.In some circuits,the brightness control operatesin reverse(rotating the control for an increase in brightness produces a decrease) after reaching a critical point on the control. If the picture wide is not accompanied by insufficient width(a symptom of horizontal output failure) the probable cause is a high volatge circuit ony,particularly the HV rectifier and HV winding.Any circuit problem that reduces but does not completely eliminate the high-voltage output to the picture tube second anode can cause overscan. The most likely defects are leaking high-voltage capacitors,defective high voltge tube rectifiers,leaking high voltage leads,defects in high voltage circuit protective resistance,and shorted turns in high voltage winding of the flyback transformer.

Hope this may help you;

I have had a bad high voltage multiplier (built on to the flyback in most models) cause the effect you are describing. When this happens it is possible for other components to be damaged.

I have also had a defective CRT cause blooming, and the colours to be very far out.

Too Bright


It could.Check the screen voltage G2,If its high more then 400v this fix could work.

Tv too bright


This problem might be caused by a problem called blooming. is the picture fuzzy and does the picture look to be streched out. Since you do not have contrast and brightness control this would almost completly point to the HV section of the TV either the control and screen grids of the CRT are going bad or the HV power supply is about to go bad, I would suggest that if you have a background in electronics that you check the HV at the anode of the picture tube and make sure the voltage is from 20Kv to 40Kv using a high voltage probe. You will need a schematic to aid you in your troubleshooting

TV won't turn on

I received this solution:
"This was apparently caused by using replacement flybacks. Add a .001uf cap (102k@2kv) from RL03 (the side away from the FBT) to ground. This will shift the picture a little then compensate a little with parameter 15."

In my case, i used an other flyback the HR8934 from Diemen to get a more stable picture without blooming, and add a 440pF (two 220pF capacitor in parallel) instead of .001uf to eliminate the tearing lines.bfde541.jpgac61dec.jpgdda8fac.jpg.
