You may have a bad B+ problem. This is normally caused from a bad Horizontal Output Transistor or a capacitor feeding the B+ circuit. If you can do your own repair, check the main components/parts feeding the high voltage section. As always, check for cold solder joints ( bad/broken solder from the printed circuit board ) and solder them if you see anything that looks different or loose. Remember ALWAY( PRE-CAUTION, UNPLUG THE SET FROM THE WALL BEFORE SERVICING AND NEVER GET CLOSE TO THE LARGE RED WIRE FROM THE HIGH VOLTAGE TRANSFORMER ( IT CAN CHARGE UP TO 30,000 VOLTS ) Good Luck on your problem and I hope this has helped in some manner.

I need to reset my password on my rca HD52W55


Hello
If your RCA tv has locked or you want to reset your password you can opt any one of the followinf option to unlock it without any passcode nd can reset it after.

Most RCA TV sets use a four digit code to control the v-chip. The code reset is different depending on the model. Try each number until you find the one that works for you.
  1. Hold down the MENU button on the remote and VOLUME DOWN button on the TV it's self at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked
  2. Hold down the 0 (zero) button on the remote and the VOLUME DOWN button on the TV itself at the same time for at least 4 seconds. The set won

I have a rca hd50lpw62a and its slow to turn on and dim when on.


If your tv is around 2-4 yrs or used 6000-8000 hrs,never replaced the lamp before it could be time to replace it.If you hear strange noises like buzzing or humming noises it could be the color wheel which is a little disc that has a gamma of colors and spins at high rpms.When the light of the lamp goes through it creates the colors on your tv.The other most common failure is the board that powers the lamp,which is called the ballast.When its bad it will make a clicking sound or like wanting to turn on.Your part # for the lamp is 265866 and you can find it here: http://www.discount-merchant.com/RCA-265866-265919-269343-271326-270414-Lamp-p/rca-lamp-265866-26591-269343-r.htm Good luck and blessing for your house!

JVC AV-48WP74


havent had time to check these things out but here is some raw research I have done

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.

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

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
