If you have zagged lines there are 10 small surface mounted capacitors you will need to change on the HYper Board. This is not an easy repair so alot of folks simply replace the hyper board. You will need a service manual to take this set apart and to get the proper part number. If you have no TV repair experience or do not know how to solder, as the hyper board has sheild arounfd it, you should play it safe and call out a pro to assist you in this repair. Good Luck

This just happened to me and it was the bulb. A fast easy way to check is to unplug your tv, remove the side door on the left side (left side if you are looking at the screen) and remove the 2 screws holding in the bulb case and remove. If there is glass in there and the wires are just hanging out inside the bulb, its done. Replace bulb and all is good again.

Just like the forum says; follow step by step and make sure to re-solder the FLYBACK and this will work! I had to pay a little more than $13 after shipping and cost of Fuse (about $5!!). Don't bother with local TV repairmen, the 10 or so I talked to are very rude and cocky people. Partstore.com was very helpful and quick with ordering, although I had to wait on a RCA Company backorder!! Thanks for the help!

The flashes are fault codes. It means your system is faulty. If it is intermittent then it is more than likely a dust issue. Buy an air duster, spray out the back and restart. Should be fine
If it continues to play up then it will be a repair job

I suspect you probably have a bad LED assembly. It could be either the red, green or blue that is bad and give you the same symptom. The problem is locating parts for it as it looks like the light engine is no longer available. I would have a technician look at the TV to verify this and what parts are needed for repair.
