To enter the service menu.

1. Changing the input to an unused input (i.e. Ant B). Turn off the set and wait for the fan to turn off. 

2. Hold input and power buttons on set down simultaneously. When service menu appears, release both buttons (input button first). 

Note any settings before you change them. I haven't challenged it but I have read online in the forums that entering the service menu may void your warranty. Service manuals are available online at ebay.

Pluged t.v in and saw spark and shut off. will not turn back on.


Hello vitto616,
This happened to one of my tv but may not be the same for you. Seems like the tv got surged. Look to see if a power light comes on. If not try different power outlets as well. If nothing then yes probably got surged. Unfortunately you may need to contact your manufacture or any local tv repair techs. Just make sure you don't get ripped off by them and see if there is anyone that will do a diagnosis for free. I hope this helps, give me your feedback if it doesn't. Good luck.

I have an ultravision projection tv that the blue and red colors appear bowed and will not refocus. Saw a posting on the convergence ic? Please let me know how to fix this problem


A lot depends on model number but most of the Hitachi sets use two convergence chips--most popular ones are STK-392-110 OR STK-392-150.

REPAIR involves getting at them and replacing them, only other part that fails is protect resistor around them. I will attach some photos so you know what the chips look like and what to look for if a bad resistor.

Total parts cost (if parts purchased on EBAY) will be under 25 dollars and typical repair takes about one hour.

This can be a do it yourself fix if you are handy. I can tell you what is needed.

If this information or the pictures told you something you did not know rate this solution as very helpful as I do this here for free.

note the two resistors that are burnt in the middle, discolored. All of the resistors are easy to test.

We just started having convergence problems with our WS65905. I performed the standard convergence adjustments and have the red/blue bars perfectly aligned. On the screen we have green and pink bleeding...


Yes, call local tv repairman to fix the issue because convergence output section got some problem like cold/ dry solder joints, devalued few resistors that can also cause of these symptoms and defective convergence output ICs are also one of bad convergence reasons in rear projection tv, all that happened because of heat and high amount of current drain in convergence circuit and its common problem of rear projection tv.
Visual check by experienced tech is necessary and repair would cost you around $250 to $350
Hope these info will help you.
Thanks.

My sony tv model # KP-46WT510 is showing a three D Picture with a red outline


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Light engine replacement


Good Day, tech;

Let's suspect poor cable connections or pinched, BUT I have received bad light engines. Make sure you ordered the correct Part Number. There are two (models) of them; check Model Number, some are 50V500 and 50V500A.

What's your input to indicate red or green???

Let me know if this helpful, big IRISH.

Sharp Aquos LC-40C32U


I have the same model TV that is 18 months old. The repairman wanted $365.00 to replace the inverter and update something on it. From what I have seen online, it is mainly just loose screws on the inverter. I called Sharp and they are paying for the repair on the TV
