That's line-to load regulation of the main power supply regulator board has the fault. There are so many reasons for this fault. In most cases, a card base replacement to this board will be good, rather than making "surgery" to it. If you're sound in electronics, and If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

I have sony model no kv-bm14m40 it blinks two times.The voltage on the CRT base which was supposed to be 200 is 235.what do I have to do to solve this problem. I appreciate any help JJ


Hello
Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits
The switched output voltage from the power supply is mor than normal. The normal secondary main supply voltage to this set must be around 135VDC. It is now been exceeded that limit, and the overvoltagg; current protection circuits in the set detects this situation and gives you tow blinks as its indication.
Normally, this fault is common to most of the Sony Trinitron sets. The main cuse for this fault is loose solderings at the SMPS power switching section. Just resolder most of the supected solder terminals by applying a little more solder, without making any solder bridge short in between the adjecent solder points. If needy, replace the secondary voltage filter capacitor [the electrolytic capacitor fitted across the 135VDC to ground. This must help you. OK.

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

I call it a 70percent chance an audio/visual cord has been damaged, if it is that, just go buy a set, they're really cheap
