Re: tv kdl-55ex620 red light blink 8 times Do a Power Reset. 1. While the TV is off, unplug the power cord of the TV from the electrical outlet. 2. Let the TV remain without power for 60 seconds. 3. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.) 4. Turn on the TV. 5. When the TV powers on and a picture is displayed, reset the TV to factory default settings.

• If the Reset message does not appear and the TV turns off and on, begin again from step 5.

• If the standby light begins blinking eight times, return to step 1.

6. After the Reset message appears, allow the TV to reset. Do not press any buttons on the remote control or on the TV and do not make any other adjustments for 1 minute. 7. Unplug the power cord from the electrical outlet. 8. Allow the TV to remain without power for 10 seconds. 9. Plug the power cord back into the electrical outlet. 10. Turn on the TV.

• The initial setup screen displays if the above procedures were performed correctly.

11. Follow the on-screen instructions to complete the initial set up. 12. Perform a system software (firmware) update.

Please do the following steps:

1. Turn on the television.
2. Please wait approximately 40 seconds for your TV to completely start up.
3. On the TV remote control, press and hold the UP ARROW button.
4. While holding the UP ARROW button, press and release the POWER button on the TV set. (The button may be on the front, top or side of the TV.) NOTE: The TV may turn off and then back on.
   
5. Release the UP ARROW button.

If the issue does not resolve, please follow these steps:

1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
   
2. Unplug the television power cord from the electrical outlet.
3. Let the television remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
   
5. Turn on the television.

power supply probably needs to be rebuilt, vertical IC some filters,probably a couple of transistors. best to have an experienced tech do it for you.

This problem is either the TV's software or how the mainboard is distributing power so instead of just unplugging the TV, try a power drain:
1. Unplug the product's power cable so the device is not grounded to the house. 2. Press and HOLD the product's own power button for 1 minute to drain the capacitors. 3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and hold down it's power/on-off button.  Electricity can remain in capacitors and on circuit boards enough to prevent normal functionality. By clearing the residue electricity, your product will have a fresh start and many times this will resolve a buggy or non-responsive device that appears to be dead.
Since hardware either works or it doesn't, your issue is either software or power related since you can get it to work so hopefully the power drain will indicate further.

There is a good chance that the failure is in the main power supply. 
A second chance is that the set is protecting itself from a failure after the supply; this is more likely to occur in the horizontal section where the highest power consumption occurs. 
If the failure is in the supply, it could be a fairly reasonable cost repair. If in the horizontal section, depending on whether the failure is limited to a $10 horizontal output transistor or a bad flyback transformer. The transformer should still be available but with markup, shipping and installation, the cost could exceed the $100 US mark.
Generally, I have been recommending folks repair their old standard definition sets, buy a converter box for digital TV, and not dispose of them since the flat panel sets are dying like flies, often just after the warranty expires.   This would at least provide some kind of set when the expensive LCD or plasma sets go belly up. 

Mike-It looks like the power supply is going on your tv-it can be replaced. This happens, usually, when little kids are playing wth the remote or power button on the tv. Turn it off and on a whole bunch of times in a row, kids love to do that, and it burns out the power supply part- to make a CRT tv like your RCA36 incher- which is a beautiful machine- I have the RCA/PROSCAN 36 incher-LAST longer...You should always wait 5 min between turning it off and on. Don't ever sell it. This one is worth fixing. It has better color and sound Than the new plasmas and lcds-The Pros know this. Be carefull, they might try and talk you out of it-so they can fix it and have it for themselves. So what if it's not High Deff. It's a great set.

You first need to rplace the outlet if it sparks where the surge protector is plugged in as it should not spark for any reason. then you need to make sure thast its not the outlet causing your problem by running an long extensition corn or moving the set to a differant outlet.
