CRT KP53S35 Unit has a LOGO of Bugs life burned into the red CRT. Unit will need the Red CRT. This should be an ICB to the store since this was damage caused by leaving a DVD player connect to the set with the Bugs Life CD in side. When not playing, and in the standby mode the logo will appear. Since the logo never moves and over a prolonged period of time the CRT's can be permanently damaged with an image burn in the phosphor Muller

CRT KP41T65. The tech is trying to replace the Red CRT but has received the wrong tube. Tech ordered from the service manual a 8-733-539-05. But it is the wrong mounting structure, and will not fit in the opening of the. Called Sony World Parts center and obtained the correct part number for the tube. Currently there is no way to find out what tube is in the set by simply looking up the number in the manual. The generic number must be compared to a new list the Sony Part has. We were lucky to find the part number on the original CRT of A-1501-367-A Muller

convergence KP53V75 Unit has and intermittent Unit had a loud pop and then the set lost top and bottom convergence , It stayed that way for twp days according to the customer then it popped again and the problem disappeared and the set returned to normal but it lost sound. 1 day later the sound returned and for the past 6 days the set is playing OK. Tech need to check the CRT sockets for the presence of the safety diodes in the on the cathodes of the power supply. Muller

convergence KP53V45 serial 9011383. Unit has no convergence control. All dimensions are way out of adjustment and have no effect when adjusting the values of the convergence parameters. Tech needs to check the protect diodes at the input of the G board. D809, D810, D807, D808. These diodes are the upgrade listed in the latest revision of TVB380. Muller

CONVERGENCE KP41T25.. Red convergence will not write to memory. When convergence is properly aligned red horizontal lines will migrate up or down after time suggest that the red sub deflection yoke plug be removed. This action eliminates the influence the convergence correction circuitry has over the Red CRT. Once this was done the TV was turned on again and the cross hatch was placed on the screen. One of the intersection points of the Red cross hairs was marked with a post-it note. The TV was allowed to run for 15 minutes. After 15 minutes the red cross hair mover 1/4 inch down the screen. This indicated the CRT was defective. The only deflection the RED tube had was the deflection that feed all the tubes. If vertical center were to drift it would drift on all the CRT not just the RED CRT. Muller

CONVERGENCE Sony KP41T65. Cannot converge set. Technician replaced all microprocessors, EPROM, and Convergence output IC's without effecting a cure I had tech check the data pulses from the Microprocessor to the DAC chips. One of the Data chips was only 3 volts peak to peak Not the 5 volts necessary to communicate to the DAC. Problem was a leaky zener diode D803. Muller

Addition of a 1SS83TD diode between (Anode)@R708 and cathode to IC (pin 6). In the event the IC is not available the CRT driver board is. CRT generic # is 07MAC2(G) The possible subs are 8-733-494-05, 8-733-561-05, and 8-733Muller

colored shadows KP53V65 Unit has purple and cyan shadows on the screen. These shadows are very pronounced when an all white pattern is shown on the screen Unit has CRT Burn caused by a DVD player or a CATV marquee that was allow to stay on the screen for an extended period of time. This apparently is caused when the DVD player has a disk in it and not playing the disk, a LOGO of the disk movie will appear on the screen. On a conventional direct view television this is not a problem if the display is left on the screen for several hours. But this is not true with projection televisions. Sever damage will result if a stationary image if left on the screen for prolonged period of time. This is especially true with Sony when it is in the external Video input mode and the DVD/VCR is OFF. All Sony's will say ""VIDEO"" printed on the screen. In 1 to 2 hours the tubes ion the projection television will be destroyed requiring them to be replaced. Replacement cost is over $800.00. Be aware, Do not leave any Projection television ""ON"" with a stationary picture. Just like screen savers are used to keep the computer monitors from leaving an imprint ""Muller
