No i is not the network. The tv's nowdays are made with cheaper capacitors that overheat and burn out much sooner than the old ones. An ohmmeter or oscilloscope is used to find the capacitor that is not producing enough power or is pushing to much power. It is likely a capacitor is burned out or high-voltage transformer if the set won't power up. The flyback in projection tv's can go out too but don't usually pop. Popping is usually the capacitor burning out.

Bad filters on one of the video processing boards. you will need to have a shop do this repair, expect to pay around $250- $300.

Needs convergance ics replaced.

Replace the convergence ics.

Red crt could be dead or could be many other things. It will require service from professional. Likely the red tube is out. This could be a money pit. The other 2 tubes could also be going out. I recommend a new TV.

Your TV has 3 CRT guns and yes one of them is red. Unfortunately it is not a simple 'plug in a new bulb and go' kind of thing. Depending on your experience with electronics and fixing things in general you may want to try it yourself. A shop will want $300-400 to do this job. If you want further info on doing this yourself post back and I can assist you.

The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

I asume you're talking about convergence IC's? The IC's themselves are about $50.00 total
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 $200-$400 Be sure to vote/rate me if this helped Thanks!

Sound to like the lamp is burnt out. I would start by replacing lamp.
Good Luck.

Howdy,

It sounds like you are having a problem in the conversion circuit. The outputs IC’s for that circuit have failed and are need of replacement. The average cost is at least $450 on one trip. Call an Authorized Service Dealer for repair and estimate.

The conversion circuit is the circuit that aligns the picture.

Good Luck, Big Irish.

Check for cold solder joints around and including the Convergence IC's.

hello press the recall button four times with in 5 seconds the pin code will be released hope it helps

Blue Signal Video Output Transistor has become faulty or the picture tube is getting weak/faulty.it has to be checked.any of the one is creating the blue tint on the screen. --------- for parts you can get it from ---- www.partstore.com ----- or from ----- www.shopjimmy.com ----- ------------ if not familiar with checking electric components.its advisable to get it checked by local repair technician familiar with this model and brand of tv.its worth getting fixed as it gets solved. -------------- This will help.

There should be a wide/screen size/ format button on the TV remote that allows you to make those adjustments.

That sounds like a problem with the geometry settings which are uusually only adjustable from the service menu area. I don't reccomend that you try making any adjustments in that area of the menu, as you can cause major problems or even irreversable damage if you don't understand exactly what the value you're altering is affecting. You may also have a problem in the pincusion correction circuit, or the convergence circuits. That may be a TV that needs professional attention.
