Hello. Can someone pls upload panasonic schematics for lcd tv TH-L32U20 my set blink 10 times error code. Thanks.

Its old_new chassis KM09 Panasonic TX-LR42U20 with matrix LC420WUN its chassi KM09 Look at Link_chassis KM09

Hello, Thanks for the quick reply i downloaded the 2files schematics but they dont match i want schematics for board A tnp4g467 th-l32u20d Thanks Mani

A-Board TNP4G467 P-Board TNP4G478 V-Board TNPA4834 Chassis KM07, TH-L42U20M >>

I check i feel the problem with p board as i do not get +12v dtv and 17v supply.only stdby 5v and 3.3v available. But hear the relays click momentarily and see primary dc hot there to the main transformer but secondry voltages absent. I noticed that ssc9512 has vcc but reg pin 9 absent.so gate voltage absent to main dc-dc transformer.anyone know about this thanks for the help

Read Link_SSC9512=SSC9502_datasheet from Sanken Below I attach a diagram of the power supply from ? Panasonic LED_backlight wer.40 (New Zeland ver.) On IC150: SSC9512. A little reconfigured than in the org. PSU from link to ch.KM07, where IC is showing on the p.69 as IC7301.

Hello all Thankyou for the help i had the set repaired today there was no main supply to the A board the problem was with the P board r7305 1megohm which go to ssc9512 there are 3resistor in series Going to pin 1.(ac in detect) Thanks again

Topic summary

The discussion revolves around a request for schematics for the Panasonic LCD TV model TH-L32U20, which is experiencing a 10 times blink error code. Users provided links to schematics for similar models, including the Panasonic TX-LR42U20, but the original poster noted that these did not match their specific board, A TNP4G467. Further responses identified related components, including the P-Board TNP4G478 and V-Board TNPA4834, and discussed troubleshooting steps. The original poster later diagnosed the issue as a lack of main supply to the A board, traced to a faulty resistor on the P board affecting the SSC9512 IC. The problem was resolved after replacing the defective component.
