Often when caps go bad they swell or blow up/leak. But it is not uncommon for a bad cap to look perfecto necessitating removal to test. Go to the enclosed web site - if you can pickup a board from them on the cheap, go for it. TV Parts Universal TV Stands DLP Chips ShopJimmy
This sounds like poor solder connections at the vertical IC. If this is corrected soon, there will be no other problems. If left as is, the IC will eventually fail. If you can solder, you can fix this yourself. Look for a small flat IC with about 11 pins attached to a heat sink. It will be marked LA7837 or something similar. If you post the model number, I can give you the exact part marking.
A basic understanding of electronics helps. I would look inside on the board and follow the traces from the hdmi back to the chip that feeds it. It would likely be an ic that has a voltage regulator in it as well as something to convert the serial port data. Write down the numbers on the chip and go to or phone an electronics parts supplier in your area and they will consult a cross reference manual to see if an after market version of the chip exists. If not they will order the original. Once you have the chip, you will need a decent soldering station ($100 or so) and a solder sucker. The solder sucker is used to desolder the chip or component slowly. Don\'t overheat the component but desolder as far as you can. then wiggle each leg one at a time until it breaks the remaining solder. If it does not wiggle off heat it again then wiggle it. Once all unsoldered gently pry out. (any other attempt to desolder without a solder sucker will damage the printed circuit traces) Before removing the ic verify which pin is pin 1. It may be printed on the board or a corner of the chip is marked somehow. Place the new chip in with pin 1 in the proper location. Use hitech solder that is hollow and contains flux on the inside to resolder. If the wrong solder is used the flux may attack the components and it will fail within a year (plus or minus). I would suggest finding someone who already does some electronics to assist you or to do the whole job.
Replacing the board would be best. You can replace the IC chip but there was a reason the chip burned out. You would need to diagnose the board and find the cause of the short that killed that chip and replace the other parts before you replaced the IC chip. By the time you do this you could have purchased the new board. If you are an experienced repair tech then it may be worth the repair but just for a user then no its not. Ebay has that board available from several sellers for less than $50.

I would suspect the trouble is one of two things---a shorted device like an IC on the board at the end of the picture tube---most sets use either 3 transistors, one larger IC or 3 individual chips---first thing is to examine the soldering on that board looking for any broken connections.
If you can find a schematic for the set voltage checks will pinpoint where the issue is---an old trick if uses 3 transistors or 3 chips is to identify which is green and swap it for one of the other 2 if numbers on them are identical.
Second and fatal possible reason is the green gun in the CRT picture tube is shorted---almost no way around that as the tube itself would have to be replaced---most modern shops are able to test the tube and determine if shorted or not.
Convergence problems are almost always traced back to the IC chips (also commonly referred to guns). You can order a new board (very pricey) or if you are pretty good with a soldering iron, it's possible to remove the IC's (if you choose to do it yourself, best to replace all 3 IC' s at once). The guns are usually in the $10-20 range apiece whereas the convergence board can run in the $300 range.
Hi, 110`s & 150`s are both replaced by stk 392-120`s. which run waaay cooler because the 120``s are rated at 4 amps while the 110`s and 150`s are 3 amp devices , the real key is to make absolutely certain you are not buying generics (which are everywhere on the internet), there should
be NO black print on the back side and a 4 digit code (not 5) on the front, top right corner, the originals or OEM`s are never $8.99, usually run about $12-15 and are made by Sanyo but the word sanyo will NOT be on the IC`s , so go by the info above, be sure to check for burnt resistors next to the heatsinks as well, good luck, video-tek
Hmmm... I dont know where to find those CTR Circuit boards I'll post my general post for you about what I know it has links to the manual and some other sites it may help.
how bad is it burned, did some chips go or just the copper circuit board tracers. you can use circuit board wire and solder it from point to point, I had somewhat of the same problem with my IC board, I had a bad portion of the board where I had to build a new copper routing with circuit wire, the copper burned off when the resistor failed, you may need to do a little Frankenstein work on your board as a last resort...remember use a low 15 watt soldering pencil, use leaded solder, and USE flux! however with all my work, I got it running but the IC board is still not running perfect. if you decide you cant fix the TV I would love to buy your IC convergence board from you. GOOD LUCK! hope I helped... GENERAL POST WITH LINKS BELOW..... 51MP392H/17 Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!
What you need: (2) STK392-120 OR STK392-150 IC chips (12) 6.8 Ohm Metal Film resistors set of star screw drivers 15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item. good leaded solder, and flux
BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com
what you need to do to solve the issue is to replace the pwr deflection board. You can get one at the following link under the samsung parts category. Its the P59A pwr def board. http://servicemanuals.vstore.ca/
