I can see you guys seem to know more about these things than anyone and I'd really appreciate some help.
I recently bought a Beocenter 1 but it's got one or two issues.
I think I have the same problem this chap has from some years ago, in that there are some wavy horizontal lines usually this seems to relate to brighter parts of the screen or those with text.

Also I have some excessive blooming on the set.In that the horizontal geometry of the screen gets significantly bigger when the screen is brighter. This isn't just 1-2% its maybe 10%
I think the two are linked, but can't be sure. I'm technical enough to open the thing up and work a multimeter. Already eye'd the capacitors and on inspection they all look fine.
Any help would be greatly appreciated. Thanks in advance.
Edit1:
I found this on youtube...though far more severe he describes a similar problem in his comments.

"This TV sports a very prehistoric power supply design, using a STR50103 linear voltage regulator with a honking power resistor in series in order to step down and regulate the incoming rectified and filtered line voltage. No transformer here.
Turns out that a 470k 1/2 W resistor was open and the 130V protection diode was shorted and disconnected from the circuit, replacing the resistor got the TV working again but with a craptastic picture and the shaking you see in the video. The higher the brightness of the picture content, the stronger the shaking.
Replacing a couple of electrolytic capacitors around the flyback area improved the picture considerably. As for the shakes, it turns out the regulator was defective, providing an excessive B+ of 125 V while the nominal value for this particular regulator is only 103 V.
Needless to say, replacing the regulator got me a correct B+ and that stopped the shaking altogether. After adjusting the static convergence and the cathode levels I got a much improved picture, almost perfect from a TV that was salvaged from the scrap heap. "
