Dear Rasheed:

For HT arcing from the wire can be solved. First of do a thorough cleaning preferably with denatured spirit from the stem where it goes inside the lot, to the anode cap. Do the same around the stem area also. Then pull the clip side of the wire through the anode rubber cap about two inches. Desolder the clip that goes inside the CRT anode. Remove the rubber cap. Do one more cleaning. Then locate suitable sleeve of any cable or two wheeler petrol tube. Insert the punctured red wire into this upto the stem. If it is not tight enough, you may have to cover the entire wire with a black tape and then insert it into this tube or sleeve. Then cut the tube at the anode side to the extent that you are able to put back the rubber cap and resolder the clip. That is all! There won't be any arcing for sure. I have done this on many TVs!

Dear Rasheed:

I do not have the schematic of this CTV. I did not note down the number and the CTV has already gone back to the customer after repair. I can help you only if and when it comes back. First of all do a test with Ring Tester and ensure that the LOT is really gone. Then if it is defective, use Blue ESR Meter and check the ohms between each winding, and make a note. The correct method is always to check the inductance, but you need an accurate test equipment, a cumbersome procedure to do it. Generally, this is what we do. Then go for an exactly matching LOT from the market. Sometimes the guy in the shop may also help you. I am sorry, I could not help you! All the best!

Hi Rasheed,

Sorry I do not have the info. You need to look for the service manual to find out the number.

I'm always calm and cool. I'm not wasting anymore of my time looking for a better computer motherboard supplier. It's not worth the trouble. She is buying a new laptop that has better capabilities and features than her old one had for less than $300US.

Hi Robert

Unfortunately these things you refer to are happening. Given that we cannot do anything so radical in order to eliminate or even only to reverse this bad behavior, the unique choice we have is to find new suppliers.
However my point was not exactly that. In any case one must remain cool and calm under similar situations and especially as regards repairs I feel that the key criterion about them is if a repair is completed successfully (regardless the possibility for the repairer having been forced to modify the circuit).
In other words if a repairer does all he can do and the final result is a working apparatus, he is already honest against himself first and against the owner of the apparatus as well. On the contrary if the repairer cannot (for any reason) repair the apparatus and he purposely manipulates it in such a way rendering it irreparable by anyone else after him in order to keep intact his pride or reputation or name it as you like, then yes, time will come and he will certainly suffer its loss. This can also happen very soon, if his customer somehow gets informed about what happened, but finally this is all natural to happen and doesn’t surprise me at all.

Greetings!

Hi Paris,
The problem is just that companies selling motherboards are completely unreliable - it's as simple as that. If you read my articles then you know that one company sold me a damaged MOBO, and another company sold me one that was no good at all. Then now, the one that worked, only worked until the warranty expired. All of them claimed their MOBO's were brand new, when I could clearly see that they were refurbished! So all of them I have experience with are liars and crooks.
But, it's not a total waste: I offered to buy the new 1T Hard Drive from her to use as an external backup; and I gained a lot of experience too.

Hi Robert

Thank you for your complementary intervention. I think that we have enough stress originated from plenty other really serious and unavoidable causes during our everyday life which we must confront with and we just need to get rid of such additional burdens that we ourselves put on our shoulders… On the other hand all we can control is just our thoughts and nothing else…
A failure in repairing an apparatus (if good will and respect to the customer is always there) is neither the end of the world or a loss of a human life as it happens with surgeon doctors. We are performing similar tasks but in human made machines and this is quite different criterion.

Thanks again
