The deflection board has failed. You would require the ITC222A deflection board which is the second board listed on the following page which has a warranty and comes with installation instructions

Sounds like a faulty power inverter to me.

If it's covered under warranty, take it back to where you got it and ask them to cover the warranty for you.

If it's not under warranty, take it to a local electronics repair store that deals with TVs. Get a quote from them on the amount to repair it.

If it exceeds a third the amount you paid for the TV in the first place (ie if the TV cost you $1,200 and the bill exceeds $400) you're better off to get a new TV.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

If this is similar to the d52w20 then I almost garantee you need to replace a capacitor. You can check to make sure that's what you need by unplugging the tv, taking off the back cover and feeling the top of 3 capacitors. On my d52w20, CP150 (rated at 2200uf 16V) was blown and the top was bulged out. You should also check CP120 and CP114 to see if either are blown. I don't have a clear picture of where it's located, but I have a picture of what you should see after you take off the back cover.

http://i265.photobucket.com/albums/ii209/fillmore85welder/KodakMoment003-1.jpg

In the middle of the picture you see an aluminum heatsink in the shape of a 'C' with the opening facing away from you. That is where CP150 is located. CP120 and CP114 should be located nearby, but if you can feel a bulge on any of the tops of those 3 capacitors replacing them should fix your problem. Replace the existing capacitors with a higher voltage rating of either 25v or 35v.

"4 capacitors on the power/deflection board. CP110 220uf 200v. CP120 220uf 35 Volts. CP114 220uf 35 volts. CP150 2200 16 volt. also check entire delfection board for cold solder especially around flyback. bad connections here can cause problems like some of the fp fuses blowing and cutting off convergence supply"

SOURCE: Replaced the fuse in RCA R52wm24 and resoldered

The fuse blows when there is aproblem with the convergence board - if the TV just had issues with the convergence b4 you soldered and replaced the fuse then the set should not be dead - I would check all plugs especially the 2 flexible (short) cables that jump the (ssb) two boards together. Do you hear the HV trying to start (a little chirp sound near the flyback) If so the set is in shutdown mode if not then power supply problems are usually the cause - check for swelled capacitors in power supply.

Picture went off on rca flat screen while watching still have sou


That probably happened because something hit the TV and broke the line for pictures to get through, or because a wire in you TV is bad and doesn't wanna work. This happened to my TV every few days. What I did is give it a few whacks every now and then on top of it and the vision came back, but don't try that if you think your TV is fragile. Yes I know its sounds stereotypical but it actually sometimes works.

Well, good luck!

Is this a projection set? If so you simply need to set the convergence. Otherwise I would try to return it to the retailer and exchange for different manufacturer.
