What you can do is get yourself a service manual from here:
http://servicemanuals.vstore.ca/

They also have spare parts and offer free online advice as you attempt a DIY. The issue is most likely a cold solder somewhere on the power board or some faulty capacitors. If you want to go in for a long term solution, you can easily replace the whole power board or just change the faulty capacitors. You will have to open the back panel and take a look. You can make out which are faulty, because their caps will be swollen on top. Here's a sample pic of a bust capacitor (not same model):

Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows this kinda stuff to do it for you, or get a qualified technician.
Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified technician to do it for you.

REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.

Hope that helps!

Tip

Hello Guys, Hold your horses or your remote... This is a very simple fix. There...


I ALSO HAVE A 52 INCH RCA (2 YEARS OLD) I HAVE TRIED ALL OF THE TIPS THAT HAVE BEEN DISCUSSED. LUCKILY I PURCHASED THE EXTENDED WARRANTY ON THIS UNIT.. AFTER A MONTH OF OVER THE PHONE TROUBLE SHOOTING FROM WARRANTY REPAIR CENTER THIS INCLUDED REMOVING THE BATTERIES IN CASE THE REMOTE WAS BAD. THEY FINALLY CAME AFTER IT YESTERDAY. THE PICKUP BOYS SAID THAT THEY ARE HAVING A LOT OF TROUBLE WITH THESE UNITS DOING THIS SAME THING. THEY ALSO SAID THAT SOME WERE BEING REPLACED WITH NEW ONES. NOT SURE IF RCA OR WARRANTY IS REPLACING (MINE WAS PURCHASED FROM BESTBUY WITH BEST BUY WARRANTY). IF ANYONE HAS SPOKEN TO ANYONE ABOUT A REPLACEMENT PLEASE RESPOND. I THINK IF THERE ARE SOME UNITS BEING REPLACED WITH NEW ONES WE ARE MORE THAN LIKELY GETTING THE SAME DEFECTIVE UNITS (WHICH WILL MORE THAN LIKELY WORK UNTIL OUT OF WARRANTY). I WISH THEY WOULD JUST GIVE REFUNDS OR CERTIFICATES TOWARDS NEW DIFFERENT UNITS MAYBE IF THERE WERE ENOUGH COMPLAINTS THIS MIGHT BE CONSIDERED.

Hi,
5 times blinks shows incorrect white balance (AKB) error. TV needs Screen Volts (G2) adjustment.
Take off lower front panel, find Focus Block that has 6 control knobs, adjust Screen volts of each CRT (red-green-blue) and problem will be solved.
Be Careful while working in TV.
Let me know if you have further question.
Thanks.
