Question about Hitachi 43FDX15B 43" Rear Projection Television

2 Answers

How many hours would you expect to get out of a Hitachi CRT Tube for model number 43FDX15B. Tube part number UE20312. Does the TV keep track of the number of hours on a CRT Tube? How do I display the number of hours on a CRT Tube? Where is the chepest place to buy a replacement CRT. I fond one at Video Display Corp that is $165 each. They require you to send in old tube to rebuild. Are there any other companies that rebuild these CRT tubes? I am buying a used Hitachi 43FDX15D TV. What would you recommed I check out on the TV before I purchase it, beside the number of hours of the CRT Tubes.

Yes these tv's keep track of how many hours on a tube. Tubes unfortunately these days last about 5-7 thousand hours. 8 if your really lucky. If you are good at repairing electronics, you can buy the caps for the tubes for about $4 each and solder them in. A repair manual may be needed.

  1. All rear projections have the option of reseting the lamp hours. This helps since you will know how many hours your last lamp ran for. Normal lamps should run between 5000 to 8000 hours.

    Try the following procedure:
    Please be cautious when entering service mode. Following the information below and you will have no problems.
  2. Step 2 Enter service mode by pressing Display, 5, vol +, Power On.
  3. Step 3 Proceed to the Option-E screen by pressing the 2 or 5 button
    Option-E 0 0
  4. Step 4 Change data to 1 using the 3 button on the remote
    Option-E 0 1
  5. Step 5 Press Mute Enter to write data.
  6. Step 6 How many hours would you - 2kba94e28fb1_thumb.jpg Image of Lamp Reset courtesy of www.agoraquest.com There is a jpeg image on this at www.agoraquest.com and more specifically at http://www.agoraquest.com/editor/upload/2kba94e28fb1.jpg

Hi,
There is no counter in TVs to show usage hours of CRTs in rear projection TVs.
Time counter facility is only available in DLP TVs (those use lamp) Plasma and LCD.
Tube UE20312 is available in Part Store for $248 and I do not trust on CRT rebuild and I do not recommend to buy defective TV that requires CRT.
Thanks.

2nd reason no red drive possibly due to a bad colour driver on the base of the tube neck.

This can be caused by a few things. The red crt/picture tube is going bad, which it would have to be replaced, tube can cost anywhere around $195 and up, if it is available. Another problem can be a bad transistor or IC on the red crt circuit board. Either way it should be taken to a repair shop. The average cost for repair could be over $300.

Hitachi 43FDX15B Convergence Failed


You will need to order part no. CZ01341. This is the output ic. There are 2 of them, replaced them both. The numbers that are printed on the old part will not match the new part, do NOT take this to hart. It is a modification that you are putting in. You should be able to do this your self. I would charge 350.00. The set is not worth much, not working. Maybe 100.00

Power light stay on


Sounds like you may have a sticking Relay S901 on the power board. Tapping the Relay may Make The Light Go On And Off. The relay part number is FJ00142 if you can find someone to work on the set for you as it would involve soldering in the new part. The number on the relay may be ALKS329 with the former part number being the Hitachi Part number.
