Brice Gideon on Nov 25, If you wish to get some details; check the site linked here. Pull up older posts. Posted datasheeh Nov 25, I have freestanding Series 8 dishwasher.

Lately during the filling cycle water hammer is occurring. How can this be resolved. Hi there, Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two. Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

Here’s a link to this great service Good luck! Posted on Jan 02, If the TV supports it, you can go into service mode by press ing the following on the remote control: It also changes channel as you press the keys, so change to a used channel to get a picture back. I am not familiar with this model, but the principles should be the same.

When making changes, make a note of the original setting so you can put it back if its not the right option.

Also only make changes 1 notch at a time. It will be obvious when you have datasheett correct option, so if nothing is happening after 2 or 3 notches, then put it back. This will minimise risk to the TV. When you have finished, look for a “Save settings” option, if not just press standby to get out of the service menu.

Posted on Feb 23, Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. Surf the site with patience.

The “P” letter will appear on the left low corner of the screen when enter P-Mode. You said “I checked vertical output line from main ic pin 23 found correct” But the problem is “Horizontal Output Line” Try that.

Have you checked all the solder terminals of the vertical output IC, for any loose contacts? Re-solder all the suspected solder terminals by applying a little more solder. Check all the low value capacitors at the vertical output section circuit. Replace all of it at once, with same capacitance and voltage ratings. If these do not help you, have to enter its service mode dagasheet to adjust the vertical height, linearity etc: By the la78004, what is the brand name to your TV?

What is the number of IC used as vertical scan output. Did you check if 24v supply is coming to datashwet chip through a fusable 10 ohm resistor?. dataasheet

Look for dry solder on the sync chip 24 pin or 40 pin IC. Insufficient height allocated how to vatasheet vertical brake pages too big. I replaced c, c, c, c I think you missed one cap. Look for another 1ufd cap close to the jungle chip.

It will have the circuit designation in the ‘s like the others in the vertical datashete. It is just not located close by. I think that one will fix it. I don’t have the service data with me so I can’t give you the exact designation. Replaced vertical IC la87040 Look for born resistor beside IC. Replaced capacitor uf 35V too!!!
