The caps you're describing are in the power supply of the DM and a very common problem. Another problem in that same box is the E2P module. The E2P is a small board towards the rear of the module plugged into the module with a multi-pin connector. Unplug the E2p and re-install the DM and see if the unit powers up... If it does the picture won't look very good but at least you'll know if the E2P is keeping it down.. If it still won't power you've eliminated the E2P as a porblem.
Next let's take a look at the error code for some clues. This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source)
Then, let me know what you find...

1. Check for no 8.4 volts DC at pin 3 of PC9A10 on the Power PCB, if low or missing replace PC9A10 part # 268P058020. 2. LED does not blink at plug in. Check for 3.3-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P109010 on the Control PCB. 3. LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067002 4. LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). 5. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 6. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001 7. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 934C061001

There is no way to tell if it needs just resoldering only a couple minutes if the vertical IC is defective most shops will say you need a new Circuit board. thats sad to say but most shops dont do component level repairs anymore, they just switch Circuit boards as they can charge more that way, and not have to reply on having the experience to actually diagnose the problem.Thats very unfortunate but true.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main 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. Pull up older posts.

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

The main problem is that you have an antique dinosaur that is well past its sell by date.

Here is an answer, but the age is the problem. An 86" Ultra HD 4K flat screen set would greatly improve your viewing enjoyment, though not the effect on your pocket!

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.
