No vertical output, but vertical ic workng fine,vertical supply ok,

Touch the input pin of the vertical IC, by the blade of the screwdriver, and see whether there is a tendency to change with width of the horizontal line on screen. If so, check and replace the horizontal, video if, vertical oscillator jungle IC. Check the frequency to the input of the vertical scan IC, with a frequency meter. If there is frequency, and still no vertical scan output, check the yoke connection, and make sure that it has no open circuit. If you wish to get some details, Pull up older posts.

Where is use tda9370

You wants to know about the use and stage which TDA9370 is used I thinks and gives you reply.
TDA9370 PS/N3/A/**** is an Integrated circuit, desigened and developed by Philips, having 64pins dual in line type. Used as an all purpose jungle IC, contains most of the TV ciruits in it, otherwise called 1-CHIP MICOM also. It contains microcomputer section, Luminance and Chroma section, Vertical and Horizontal oscillator section, and all other sync: sections for the Tv., and have electronic switches and other integrations to receive signals form out,and to give sgnals to out. will be a little costly, as ti contains so many sections and integration process is a little bit difficult. OK.

I would lke to know the reference code on the audio out put ic, used in the VHF MARINE IC-M302.

Quick description as per ICOM Manuals:
The AF amplifier circuit amplifies the detected signals to drive a speaker. The AF circuit includes an AF mute circuit for the squelch. AF signals from IC1 (pin 9) are applied to the de-emphasis circuit (R61, C89). The de-emphasis circuit is an integrated circuit with frequency characteristic of –6 dB/octave. The integrated signals pass through the high-pass filter (Q5, R62–R67, C90, C91) to suppress unwanted lower noise signals. The filtered signals are applied to the AF mute circuit (IC7B), and then passes through the [VOLUME] control (VR board; R1) via the “VOL1” signal. The signals are applied to the AF power amplifier (IC6, pin 1). The output signal from IC6 (pin4) drives the internal (external) speaker.
I thus assume the IC you are looking for is the IC described as IC 6.
Data sheet availible online:
The IC is a Sanyo LA4425A. A 5W Power amplifier.

Red shadows in 48" JVC rear projection

Well you better be pretty handy with a soldering iron. The convergence output IC's need to be replaced. These are large plastic pack IC's with 18 or so pins that are soldered on the underside of the circuit board. These IC's are mounted to large metal heat sinks.

Sony trinitron 6 red lights

Every part has its unique reference number on schematics and PCB of TV installed.

C515 means Capacitor # 515 and IC206 means Integrated Circuit # 206 mounted on PCB and shown in related schematics.

Jungle IC is technical term used in Sony and Panasonic refers to sync, oscillators, drive stages for horizontal and vertical deflection stages in a TV.

Need further info, let me know.

JVC AV-48WP30 48 in. Rear... Problem

Your convergence I.C's ( integrated circuits ) Have failed. Replace Both I.C's with Stk392-150's. The unit is equipped with 110's. These are large IC's pn the convergence board located near the front of the unit. You need soldering/desoldering experience to do this job. I would recommend seeking professional assistance.
