SOURCE: JVC AV-48WP30 48 in. Rear Projection

this is the raw research for this that I have found. It seems like the most likely culprit for this is the stk chips on the convergence board (JVC didn't put nearly enough heat sink compound on should be a small layer all the way across they put on a couple dabs) I hear tale you can check this out by disconnecting the convergence board and turning on the set . only go after the convergence board from the front (behind the speaker grill is another panel, the convergence card is right behind there) there is a sneak circuit which will kick in possibly destroying at least the dvi input and mabie more if the set is powered on with the back removed and you didn't put a jumper in the right place or cover over a hole in the back of the dvi module (supposidly to keep people from hacking movies, like there arn't easier ways to do that if you really wanted to). if that doesnt fix it then I have found several other possibilities but I am now a few hundred miles from the tv that I was working on so havent had a chance to try this out:
No. The CRT driver ICs are prone to shorting and cause this symptom (I just had one with those very symptoms and the green CRT driver IC was shorted). Disconnecting the CRT board does not clear the short on the board. Often then is a small burn mark on the CRT board under the affected IC (but not always). The IC should be a TDA6111Q. Be sure to note the proper position
of the IC as it should face with the letters TOWARD the heat sink!!!!

Larry, Check the CRT driver ICs on each of the CRT boards.

Hi Guys, I don`t see many JVC`s and don`t have the print for this AV48WP30, went out this morning and as customer claimed on phone when you plug set in and turn on it makes a loud thump thump in both speakers 20-30 times then relay clicks, the thump stops, and blue idiot light on front goes dim/bright, dim/bright, have to unplug set to start this same scenario over again. Never develops HV or audio, Will order the service manual today, but would like to know if anyone has seen this before (should say "heard" this before)
I would disconnect each crt board and hv lead one at a time and try. Have seen several bad tubes on that model. The only other problem I have seen on that set is bad convergence amps, however that doesn't cause shutdown.

From Tech Repair CD:
JVC\AV48WP74\just went click*click*click when turned on Video drive IC (IC1101) on the red CRT module
shorted. It looked like bad solder on the B+ was the cause

STK392-110
Above from JVC Web site, also I have seen shorted video drive IC's on the crt boards short and cause this symptom. Try unplugging the 200 volt source to the crt boards and see it the set powers up and stays on. There is a B+ relay which supplies 130 Volts to the horizontal output circuit. Is this relay energizing? I takes about five seconds after the power is turned on for it to energize. If a short is detected on the 130 volt line the blue power lamp on the front will do what you describe and the relay will pulse on and off. (David)

Symptom:
Non-functional Digital Input
Solution:
1. Power off the unit
2. Disconnect the digital input if it is connected
3. Remove the rear cover
4. On the digital input module, using a shorting pin (PC type) or a
jumper, short Pin 1 and Pin 2 of the
SB connector
5. Power on the unit
6. Unplug the unit and remove the shorting pin or the jumper
7. Re-attach the unit’s rear cover
8. Power on the unit, and input the digital source

SOURCE: HDMI input failure

Hey guys, had the same problem. Found this solution on the web. Worked for me.

JVC HDMI Port Fix

Turn the TV on, and enter the Service Menu. Select 2 for Self Check. Then turn the TV off, and after the fan turns off, unplug the power cord. Reconnect the power cord, turn the TV on, and the HDMI port is reenabled.


Here’s how to get to Service Menu:

Before entering the SERVICE MENU, confirm that the setting
of TV/CATV SW of the REMOTE CONTROL UNIT is at the
"TV" side and the setting of VCR/DVD SW of the REMOTE
CONTROL UNIT is at the "VCR" side. If the switches have not
been properly set, you cannot enter the SERVICE MENU.
1) Press [SLEEP TIMER] key and while the indication of
SLEEP TIMER 0 MIN is being displayed, press
[DISPLAY] key and [VIDEO STATUS] key (Fig.2)
simultaneously.
2) The SERVICE MENU screen of Fig.1 is displayed.
3) Verify what to set in the SERVICE MENU, and set
whatever is necessary (Fig.1).
Refer to the SERVICE ADJUSTMENT for setting.
4) Press the [BACK] key to return the SERVICE MENU.


This should work.

SOURCE: 52G786 ATSC Tuner no longer works

I have the same exact model tv...Love it...ATSC tuners is in definition an Analog tuner. As the broadcasting companies change over to Digital broadcasting before the deadline in Febuary 2009 more and more local or Non-Digital chanels are becoming obsolete. You would have to purchase a converter box for your tv if your not planning on getting cable. Another way to gois if you have an old cable line running through you house (no incomming cable) plug you tv into that jack. That also acts as a antenna. The sweet part of all this is that your tv do have a QAM tuner or Digital tuner built in just need that digital antenna to pair it up.

#dhb300b DVD player plays only black and white my TV is a JVC HD TV with HDMI cable from driver TV box hook up DVD to TV audivo to audivo video to video set TV to component program DVD to TV but plats


The yellow/red/white cables are COMPOSITE cables. COMPONENT cables are RED/BLUE/GREEN. You can buy those at any electronics store. Your best bet, though, is to stick with HDMI if you can.

Hooked up an apple tv (for netflix) to our jvc i-art 48" projection tv directly through an hdmi cable and a HDMI - DVI converter jack on the back of the tv. Fantastic picture quality but no matter...


Depending on your model number but most of the AV48WP30 and 74 series have a built in safety feature which has been known to wipe out digital inputs if the rear cover has ever been removed without disabling that feature with a paper clip first. What is the actual model number of your set?

I have a 55" LG


Easy solution; this is a very common problem. Connect Cable or satellite box / DVR directly to one of the TV HDMI inputs. Connect an optical audio cable from that box to receiver so sound is surround through your speakers. You cannot connect DVR directly to receiver because the anti pirating chip will shut off the picture and produce a green or no screen at all.
You can, however, connect a BD (Blu-Ray) player via HDMI cable directly to your receiver without that problem. Connect HDMI output from receiver to a second HDMI input on the LG.
Contact me if you need more help! All the best, John

My JVC HD-56G786 will not work with HDMI cable. when I connect the HDMI cable I get a green screen. Any ideas would be great.


I had the same problem with my JVC projection tv. It would flash green, then go to regular picture then back to green flashes. Not sure if this is the solution you were looking for, but I was able to get a good crisp picture using composite cables instead of the HDMI cable.

No owners manual can't get new blue ray dvd player to work on tv


Here is the manual:

When using the HDMI connections you may have to tell the DVD to output to that port.  Also you may have to connect additional sound cables from the DVD output to the TV.

Setting up Unit


I called the JVC tech service rep. I went from the Cable box to the JVC unit with a Digital Optical Cable, from dvd/vcr player to jvc unit with a Composite Cable and Audio Cables. From cable box to tv with hdmi cable and from jvc unit to tv with componet cables and cable box to dvd/vcr with Audio/ Video and S-Video cables. This allows me to have the cable TV access and Surround sound in all mode. I have HD and Digital surround sound in three diiferent modes. Everything is working great.
Thanks for the opportunity for help just the same.

42" pansonic plasma hdmi problem

Hdmi not working


You need to set up the out put of your DVD player. First hook up a non hdmi output to the tv, either component or coax. You don't need to hook up the audio. You should get a picture from this connection. Then you can go into the menu and set your hdmi output to match your tv, probably 1080i. You may have to turn your volume up higher when using the hdmi cable than not. I hooked my audio up directly to a surround sound and don't use the tv's speakers.
