| Sony | KP41T15 RA1 | RASTER | KP41T15 Unit is turning on. Timer light flashes at turn on and set will have sound, but no raster. | Unit has no high voltage. ""E"" board is wet from glycol coolant leak from the Red and Blue CRT's that are leaking Red an Blue tube "" | Muller |
| Sony | KP41T15 RA1 | Dead | Unit is Dead. Was hit by a power surge. D655 was defective. Unit still will not power up after the device was replaced | All power supplies are normal in operation. Unit has Horizontal sweep when checking the Q505(C) we have over 900 v peak to peak . We do not have High voltage or high voltage drive to Q801(B) or Q810(B) find no horizontal drive. Checking the HV protection circuit finds the IC902(1) is sitting at 6.2 volts. This is because IC902(7) is higher than IC902(6). This is attached to the OCP circuit. It is conceivable the flyback is shorted due to the fact the 135 vdc OCP line is being triggered. Unit did have a shorted | Muller |
| Sony | KP41T15 RA1 | DEAD | KP41T15. Unit has coolant leak which destroyed the ""E"" board. "" | Unit will need a replacement ""E"" board. "" | Muller |

| Sony | KP41T15 RA1 | DEAD | KP41T15 serial 9012082 Unit has a burned hole in the ""D"" around R1625, R1627, R1629, & R1621 "" | Board will need to be replaced. Hole is approximately 1 inch square hole under IC1601around the current limiting resistors. Board number is A-1346-296-A and is no longer available from Sony World parts center | Muller |
| SONY | KP41T15B | imagem normal mas, sem som | bobina de alimentação da placa traseira abera | L1105 | ELETRO CENTER |
| SONY | KP41T15B PADRãO | Liga por alguns segundos e se desliga em seguida. O led stand-by, permaneçe aceso. | Encontrei resistor aberto de 6K8, 1/2w, que alimenta o drive horizontal. Antes, meça tensão de alimentação do transistor Drive horizontal. Certamente a tensão de coletor fica nula. | csc eletronica | |

| Sony | KP41T15 | CUSTOMER CONVERGENCE IS NOT RETAINED. IC003 | Customer would adj his convergence and picture settings andthe next time they turned the set on the adjustments were lost. SOLUTION: The memory IC for the customer controls is IC003. The memory IC for Dynamic Convergence is IC005.Note: | ||
| Sony | KP41T15 | SLOW CHANNEL CHANGE AND BLANKING, REPLACED Y/C JUNGLE IC | After a couple of hours, changing channels would take longerthan normal and picture remained bland during that period. Picturenormally blankds during channel change, but in this case was very ievidentdue to delayed operation. Channel number display a | ||
| Sony | KP41T15 | RUBBER CAP AS PER I/M PART NUMBER4-050-330-01 | Instruction Manual shows rubber caps as a accessorie, butdoes not give a part number. Nor, does this part appear in the ServiceManual. -HQ COMMENTS: The part number for these caps are 4-050-330-02. | ||
| Sony | KP41T15 | 15V FUSE BLOWN/UNIT WOULD SHUTDOWN | Power on -15v fuse on d baord would blow. | ||
| Sony | KP41T15 | DISTORTION IN RIGHT CHANNEL AUDIO, REPLACED IC202 | Customer reported a loud crack noise, then distorted audio.Analysis in home revealed distortion in right channel only speaker checkedok. Distortion was also present when video 1, 2, 3, modes were selected,using VCR etc. -SOLUTION Replaced IC202 and IC | ||
| Sony | KP41T15 | DEAD, SHORTED AUDIO OUTPUT IC | No power. Found power supply dead and shorted Audio output IC. Reported by Ted Kim, Kim's Electronics | ||
| Sony | KP41T15 | DEAD, REPLACED D803 C808 AND R854 ON E BOARD | The unit has no power, check the power supply and high voltage. I found unit lost 200V. Reported by Ted Kim, Kim's Electronics. |
