Most of the time TV problems arise by power supply noise. This noise in the supply is usually caused by Electrolytic Capacitor failure. If you are technical, you can get the schematic and look for the voltage regulator circuits. Measure the voltages with a DVM using both the DC and AC settings. If the DC setting is lower than normal, you will probably see about .5 to 1v of AC voltage on the line. Look for the large capacitor in the regulator circuit and replace them. Cost about $.50 each. Get new caps with slightly higher voltage rating (if they will physically fit).

Five blinks is the error code for an AKB (auto kine bias) error. What this means is that the set isn't able to balance the three color guns (red, green and blue) of the picture tube properly, and it's blanking out the screen.
To get the proper colors, the signals for the three colors need to be balanced, and Sony sets have circuitry to do this automatically. Other brands don't, and when they go out of balance you see a picture that starts to show tinting or colors that are off. As the picture tube ages, it gets harder to adjust the balance until finally the AKB circuit can't anymore, and poof, the picture goes away. With a 17-year-old tube, it's not surprising.
There isn't anything that can be done to fix the picture tube, it would need to be replaced. But the cost of the tube and the work required to get it set up after installation makes it completely uneconomical to repair this TV. A new picture tube is nearly $200. Then special tools are required to
set the tube up (a process called convergence), so you'd need to find
someone to put it in, and possibly pay to have the old one disposed of. A new 32-inch LCD set is around $350 now. Treat yourself to a new one.
Yes, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:
sometimes picture tube tvs develop shorts between the internal electrodes usually cathodes to filaments causing the one or more of the guns inside the tube to go high in emission, when this happens the screen or picture you see will get excessively in this case red and some horizontal diagonal lines will also show causing the tv to shut down, another condition that may cause an excessive red screen may be a failure of one of the voltage source that feeds the color amp in this case the red ampl, this also may cause the retrace lines and tv shutdown.i hope this explanation helps you better understand what might be going on with your tv. In both cases technical analysis will be required and in some cases even the picture tube condition can be corrected with out having to resort to a picture tube replacement. i hope i answer the your inquiry to your liking and if so please let this site know by leaving some pos feedback.
this sounds like one of the tubes is shorting out ,or have you or do you know if your tv tubes have been serviced and the fluid checked in them reciently.i know sone tv proj carries some kind of solution in the tubes to keep them running cool ,call a service rep or the panasonic co and ask them tech support
Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.
Sounds like the red picture tube could be shorting internally which would cause the "all red" condition. In which case you'd have to replace the red tube. Are there horizontal (slightly slanted) lines through the picture as well when this is happening and a very very bright screen? If so it's most likely the tube.
It is probably a convergence problem which would involve solder work to change convergence i.c.s or if there are not colored shadows around everything it could be a problem with tubes. On a few of these I was able to remove the front grill and take off the small door, and with an insulated screwdriver gently tap on the neck of the tubes with the set on. Now if the picture flickers you have some particles on the filaments of the tubes and sometimes the debris will break free when you perform this, allowing your picture to restore full color and brightness without changing any parts whatsoever. Otherwise, the convergence chips are located on a large metal heatsink and have a generic part number printed on the front of each. Sometimes you have to remove a pressure clip to see it. Hope this helps, Russmann.
Color tubes are OK. Do not adjust. The issue at hand is called
convergence alignment.The repair involves-------
2)Replace convergence IC's
work should be done by a skilled technician........T.
