Part of your feedback voltages are now incorrect. Find the solder bridge and remove it then see if you at least get back where you were...accordianman

Really, the only test you can do statically is to make sure that there are no open windings. There are some shops that can "ring" the windings to see if they resonate properly, but if you've gone to the trouble to remove the FB, you might as well replace it, especially if you already suspect it to be your problem...accordianman

Are you using just one box on this set. I suspect a bad set-top box...accordianman

It sounds as if you have a grid to anode short that is inconsistent. I would try to get the warranty company to just go ahead and replace all three tubes and be done with it. But, this is only my opinion, and past experiences with these sets. An aside; the more brightness level you ask of the tubes, the more this can be aggravated, as a general rule. Try different sources and program content and see if this is the case. Those scenes with more luminance (brightness) will stress the tubes more than low-level or dark scenes. See if that helps...accordianman

Turn the power off. On the front of the tv hold down menu then power then channel down, in about 8 seconds the service menu will come up, go to geometry and write down the original settings before you begin. Adjust, check store and hit menu to exit. Problem solved........NEXT!

Reedasaurus resolder your flyback.

Neednonrcatv, you need a new flyback you can get one at the following link with free tech support so you can install it yourself, very easy repair you need flyback number 259296 heres the link.

I suspect convergence ics part number startswith stks they are black and on a silver heat sink. if you could solder you could do it.If a tv shop fixed it the cost would be around 295.00. parts are 30.00 total. www.mcmelectronics has parts. to find out part numbers they are located on the board on the back.

thanks doctor video

you probably need a convergence board that sounds like what your problem is....you can go to the link I posted leave them an e-mail with model number and trouble they may be able to locate you one

suspect the optical engine as the culprit. they can gather dust contamination internally and cause a "faded or washed out pic"

The flyback transformer is probably bad...it has a large red
power lead coming out that goes to the HV divider....need
drawing # s off the body of transformer to confirm correct
part #.....................T.

Well what may have happened is a bad thing, See if you can find some way of displaying a totaly white pix, and have this full size filling the entire screen. If the side bars are still there this means the CRT's are burned and this is a perminate thing, The fix would be to change the CRT's mabe just the green and the red but they still run about $285.00 each. This was cause by having the set run in a format that DOES NOT fill the entire screen

The chirping sound is the power supply coming up then breaking down because there is a short somwhere in the high voltage. The most common fail in this area is the horizontal output is shorted ( 237470 ) but what cause this short could be simple cold solder joints or the High voltage transformer ( 239111 ) If you have noway to "ring" the flyback change both parts

This is a terrible thing to tell you, but, what you describe is called dijitizing then the light engine failed Now it gets real bad ,,, This part 261589 is about $590.00 and is on factory backorder with no ETA in site. We have been waiting for one of these at our shop now for over 5 months. RCA knows about this problem and you might want to give them a call and see if they will do anything

this is an idication of trouble with the red tube. it might be as simple as a crt board or the tube might need replaced. i would have to open it up and see. the crt could be leaking or the high voltage to that tube might be missing. as a technician i would have to see if the red tube or one or more tubes are powing up.

what format is it in there should be a format button on your remote

in setup do you choose cable or uhf ?

did u have a lightning storm or a power surge. sounds like too much of a coincedince for both to go down with out a spike in the electrical supply.

you should take it to a tv repair shop to look it over, they charge $50 and they will tell you want the problem is.

changed the flyback? why ...did u check the horizontal ouput transistor. usally they go hand and hand with flyback

the lamp unit is going out - cost 155.00 to fix
