Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Depending on the intensity of the power surge, it may not be worth fixing. You could have damage to the power supply plus other boards. You will need to have the set properly diagnosed. Being that you have a 32", if you can fix it yourself, it may be worth fixing. If you have to take it to a shop, it won't be worth fixing seeing that new 32 LCD's can be bought for under $200 nowadays.
The X-Ray Protect circuit monitors: * Excessive High Voltage * Excess CRT Beam Current * Excess HV Circuit Current
X-Ray line is normally High. If any of the monitored sources exceeds
its' specific reference, the X-Ray line is pulled Low, shutting Off the
TV. If X-Ray protect shuts the TV Off, pressing the Power button will
turn the TV back On ( it will shut Off again if the problem still
Possible Problems: Power Supply Fault, Sweep Circuit Problem, Doubler Board Fault
or a leaking CRT. You may have bad capacitors in the power supply or the
sweep power supply.
Check for CRT leaking, few drops of clear light oil. If this is leaking the fix is costly and not worth fixing. Inspect for puffy capacitors on the power supply and sweep circuit
boards, if you can solder replacing capacitors is cheap, middle pricing for replacing power supply or circuit boards.
You likely have a power supply capacitor(s) that has gone bad. This is an easy fix, and I suggest you search youtube for "samsung capacitor" and you should get some good videos how to repair it if you can solder. If not, any friend who can solder can probably help you repair this with a couple dollars worth of parts form Radio Shack.
If the TV is totally dead, check the fuse. Check power supply components. unless it is accessed for circuit damage it is difficult to say whether it's worth repairing. If you have Insurance take the claim.
Sounds like capicitor could be faulty, shouldn't be that difficult or expensive to replace. What will cost you more is the labour so depends how expensive they are on that, if it's not too much then yeah it's worth fixing just ask for a quote first.
The picture shrinking is an indicator the the regulated HT power supply rail is going low in voltage resulting in EHT supply for the tube doing the same. . This will relate to component failure in the power supply itself, probably capacitors. It will progress, and eventually the set will stop. To be totally honest with you, it could run to $180-250 to overhaul the power supply and a few other areas of concern in a set this age. They were always a little on the "cheap build" side to begin with, so I would not recommend you spend anything on it, your money would be better put towards a new one. I know that this does not fix your problem, but is advice from a TV tech that knows. Thanks for using FixYa. I am happy to answer any other questions you may have. A FixYa rating of this advice to you is a great reward for the time I have taken to address it with you. Cheers
Generally power supplies are difficult to fix if something's wrong, and it probably would cost more than they're worth. You're better to just spend the money on new ones. They aren't too expensive to replace. Unless it's something visible on the outside like a fraying wire or a broken connector, which can be fixed with a bit of solder and shrink tube or maybe an extra connector, you're better off replacing than repairing.
hello. well your right it's a power supply problem. and about the color tube. .you can find one for around $75.00 to $600.00. yes that's right. that much.!!! and i think that you will have to pay to much to fix it.!!! it'se to get a new set. !!! hope this help's you.!!! "GOOD LUCK"
