The tv have a problems known as a convergence problems,it dead.The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.The tv convergnece board,must have these parts changes on the tv convergence board to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.
The problem you are experiencing is known as short protect fault. It happens when a component is shorted(usually in the power supply circuit). Now do you notice any pattern of blinks after it turns off like 7 blinks, pause and 7 blinks...
Please provide this info so that I can pin-point you to the source of the problem. Sai.
Hi, Three times red light blinking indicates problem of convergence output chips are bad, tv has 2 chips that need to be replaced. Let me know if you are handy with electronics stuff repair and can replace/ solder parts in circuit board to provide you technical info OR local tv repairman will do this job for you. Thanks.
Hi, Please replace convergence ICs in tv, there are two big black ICs that has number STK392-110 mounted with big aluminum heat sink, replacement these ICs will solve your tv problem. Also check big resistor nearby these convergence ICs and replace if found burn mark or color faded. On circuit board, IC location number is IC7001 and IC7002 Let me know if you have additional question. Thanks.
The first step would be to use the original remote to fix the convergence problem. You need to go to menu > convergence and then try to align the convergence.If you are unable to fix the convergence by remote, you need to open the TV and replace convergence IC's. This is a simple fix.
If you have an electronics repair experience and would like to repair the TV yourself, revert and i would guide you how to replace the convergence chip on this set.
The tv 100% have convergence problems,it dead,if have any colors lines mis alignment or don't stay in the convergence - + grid.The tv convergence board is dead.The 2 STK convergence ICS and some or all is resitors are dead.Must replaced these parts on the tv convergence board to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.
Could be anythings wrong with it,must hire a tv Tech.to troubleshoot and repair.Because doesn't know the causes and the problems was in storage 5 years ago.Tries check all cales wires plugs in connections are tightly connected and no loose connections wires on those PCB boards,might help make the tv it work again.
Hi:
You do not have to worry about lamps in this unit as it does not use one. This perticular uses CRT's like the ones you look at with a standard Tube set. There are three picture tubes RED GRN BLUE, There is no parts needed for your television that are consumer replaceable. The only required maintence need is cleaning and Convergence Alignment, Conv alignment is the line up of the all there screens for picture clarity. you may find this alignment in customer mode in your menu.
\A more percise is in service mode in which technicians use for fine alignment.
If you cannot move a certain color, red or blue then you may have more going onthan just an adjustment. What you might be experiencing based on your symptom sounds like a damaged convergence IC. With any Projection Television that has a damaged convergence IC, you do not want to continue the use of the set. If the IC’s continue to fail they will cause a short in the power supply and cause your television to not power up, and possibly damage the CRT’s in the set. With that aside I have some support suggestions that I have put together that may help you make an informed decision.
You should be able to get a local service center to repair this at your house for between $350.00 - $450.00, If you want to repair this set yourself, I have some instructions below that will be a help to you. While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.
When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.
There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110.
Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need. Their site is http://www.andrewselectronics.com/welcome.aspx And their phone number is a 24-Hour Order Desk: (800) 274-4666 I recommend the phone order so you can talk to the person about the different types of IC’s that are available.
I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.
You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.
I hope this information allows you to resolve this issue. If you need further assistance please comment to this post and I will try to help you further. Thanks for using FixYa asnowman I have attached some photos of really bad convergence problems; your picture may not be exactly as bad as these.
Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.
The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.
