Question about Hitachi 51GWX20B 51" Rear Projection Television

2 Answers

Hitachi 51" projection tv has sound but no picture...help!

We had an estimate to fix it for $450 in which the supposed expert was rambling on with mumbo jumbo. Could this be a less expensive fix for us? This set is only 4 years old. Model #51GWX20B Thanks for any help you can give.

I founfd this, it could be the problem. Symptom: NO VIDEO Cause: Found L306 was open. B+ to pins 21,22 of PFC2 at the FC. find L306, will be hard to find with all the boards, but L306 is a coil. if you can find it use a multimeter to see if it's open. 450 sound slightly high but if you have a service call or pickup & delivery it might be right. hopefully you find the coil bad. good luck.

I used Hitachi TV convergence repair kit to fix tv


Check the Components received are compatible with manufacturers numbers or if they are generic the voltage,ohmage,ampage and resistance must be almost the same.

Using a multimeter take out and test each individual components.They could have sent you faulty parts.

Ensure you follow the instructions very carefully when soldering them onto the board.

Hope this helps you

If it is in EXCELLENT shape, 500 is not too much, but I would only offer 400 or 450. Hitachis seem to be pretty solid units. Ask if they have had any work done to the tv when you pick it up so you can know what to expect.

Hitachi 51F59 51 in Projector no picture or sound


Resetting the tv by unplugging is definitely a good idea. dusting doesn't hurt either, because the dust can sit on the circuit board. when the dust heats up through use, it can cause damage to the circuits that unplugging and replugging won't fix :-)
