What most likely happened is that the person who checked it saw that there was a fault in the operation of the mentioned board. But, what he could not see because of the complexity of the set, there is a problem somewhere else that is causing this failure. There are many interactive circuits where some sections will effect others on different boards. The different boards have a high degree of interaction between them.

These TV sets are extremely complicated. What is one in the factory service, is they test the set by doing a number of test measurements, and then trying out the suspect boards in a group. Then they use the process of elimination to zero in on the faulty board. When they find the defective board they leave the new board in the set, adjust it according to the service information in the service manual, and then return the set to the customer.

Like computers, most of the service is done with board swapping. The authorized service rep will have the instrumentation and service setups to do the proper calibrations to match up the new board.

This is why I never encouraged a customer to service his own TV set. He can end up buying parts and boards that he may not need because he was testing the set by guessing. These boards are not returnable, because after the board was handled and tried, there is no guarantee that a new problem was introduced on the board. Sometimes there can be a problem on another board that damages other boards that are connected to it.

In the end, we found that it does not usually pay to try to service these sets yourself. At home you don't have the facilities to properly test the set for calibration and performance. You also don't have the diagnostics facilities, training, and engineering information to be able to properly work on the set.

    The solution is to send the set to the factory service rep to have it properly serviced. If you send the set to a non factory rep, he will end up sending the set for you. If he took it on himself to borrow a spare set of boards, he may not have the setup to properly calibrate the set after the boards are replaced.

    In going by your description, it appears that the video processor is not having proper clock rate locking from the encoded video signal. The decoding and processing of the video signal is not able to sync lock. This is controlled through a PLL (Phase Lock Loop) circuit that is part of the main processing on this board that you replaced. This is why the person who advised you recommended this board. The fault may be coming from the input processor not processing the reference clocking signal on the input board, or it may be from a fault with the master clocking counter that is from the uPC (Micro Processor) that is for the main system sync, or for the main video processing itself.

    To service your set at the level that I am mentioning above, the service man would need a very extensive and costly setup. For a tech to work at this level would be very time consuming, and he would have to have an extensive in depth knowledge of how the set was designed. This level of service would be more at the factory R&D level. None of the service reps would do this level of service. They would simply swap out boards for new ones until the fix the set. Board swapping is the most cost effective way to service this type of TV set.

    I was telling you the reason why these sets are not able to be self serviced at home even by someone who has a solid TV electronics background. He would have to have the factory training, service setup, and facilities. He would have to invest a lot of money and time in to servicing it just to service one TV set!

    At the service rep, your set would be serviced by doing board swapping. After the defective boards are replaced, the tech would follow the instructions in the service manual to do the performance tests on the set. He would then follow the service instructions to do any necessary calibrations to match the new boards.

Look for bad capacitors in the vertical deflection amp, and in the pin amp sections. This is common on most of these types of TV sets.

The caps tend to go high in ESR with age. It is best to use an ESR meter to find the bad caps. It will be a lot faster than workign out waveforms with a scope.

now only visible in a thin horizontal line. first of all you reduce brightness to monimum. it just to protect your tv from crt demage. your problem is in horizontal output section as you have mentioned that week or so ago the right and left bottom edges of the picture began to move in like a sideways triangle filled with black so this sympton is due to hor. section problem. your flyback transformer or horizontal output might be defective. but remember check for power supply is ok from surge protector hope this will help.

This sounds like one of the capacitors has dried out. They are metal cylinders containing 2 rolled up strips of foil separated by a gel. Over time the gel can dry out an eventually the strips of foil touch creating a short circuit. A TV repair shop should be able to replace the faulty component relatively easily. I wouldn't recommend trying to do this yourself unless you are very confident you know what you are doing, the voltages present in a CRT TV are very dangerous.

You have a bad connection on the CRT board thats mounted on the end of the picture tube it sounds like, or the socket on that board that plugs into the TV set is intermittant or has a bad solder connection on it. Good Luck
