From your brief description, It sounds like you lost your ground connection. Check the Negative (black) terminal connector on the battery, and check where the cable connects to the chassis.
Even if I misunderstand your description, that should be a good place to start!
Hello Ronald Will you please come over me by my Email address. I'll give it you here. I want to get some more details about your doing, and other things that I want to know, before posting a solution to your TVs' problem. Without knowing details, posting a solution will be for nothing. By Email, I can send you the details, and you can send and ask doubts to me. Isn't it best? Come over me by [email protected] Give me a brief description about the fault occured first to your tV, repair work you have done to it. Give ma a brief description by Email. If it is with Email, I can send documents, pictures etec to you that will help you too. OK.
Hello
Will you please give me a brief description about how your Dynex is connected to security camera device? It will help me a lot to troubleshoot. OK.
Hello
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.
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: http://www.datasheetcatalog.org/datasheet/sanyo/ds_pdf_e/LA4425A.pdf
The IC is a Sanyo LA4425A. A 5W Power amplifier.
There are a few IC's listed for U701 and U501 - Rca does not go by part # listed on the IC itself - give me a description of the IC's- that is what circuit their used in and what's their purpose and I'll give you the RCA part #
simple go to google and in the search box type unidentified drivers and in the first option download a software which will tell you every thing about *********** board and later I will give a site to download all the drivers at one go
next to the ics you will see some fuses(one on each) 5A they look lke a resistor but they are green. there is one for each ic, get a meter mesure both fuses and the one its open its next to the bad ic.
Ok, a really brief description you got there, so the answer will be big.
There is two main things you go to do. One on your PC and the other is on another person's PC.
first, you got to test your printer on another PC to isolate the problem. If it worked then it's a problem in your Printer driver, uninstall reinstall or update.
If it still has the same problem, then you have to do the same on your PC, uninstall your Printer Driver, reinstall then if still has the problem upgrade your software.
Still not working? you have to open-up your Printer, unscrew the screws on the outside then check the board if there is a burned IC or resistor. Maybe something you can barely see.
The last option is for a technician to check it.
Good Luck.
