RE: Beko

:D We have repaired quite a number of these sets and are not at all impressed with them.The most common failing is in the line output stage-lopt flashover which does destroy the line output transistor-sometimes due to ht problems,flyback tuning failure and the line drive is some times incorrect which also destroys the line o/p transistor on switch on.
As regards the bush sets-the AK19 chassis are as bad but reliability is much better after they have had their first (and very soon after the guarantee hads run out) sevice.
Known faults are again to do with the line o/p stage(most common ones ive done)= picture too wide=no e/w correction due to o/c feed resistor for e/w modulator.Caused by poor soldering at one leg of capacitor c630-which will also destroy the line o/p transistor.
picture too wide=d612 failure,picture int,too wide=poor soldering on one leg of L602.
The list could go on and on ,the main causes of these failures seems to have a lot to do with the soldering of certain components in the line out put stage of these sets.

RE: Eltax Casa DVD/CD combo skips and clicks

:) Your problem seems to be a regular thing with most dvds i come across for repair-the cause could be a number of things ,the main one due to emmission problems with the dvd optical block.You could cure it temporarily by altering settings in your dvd players service mode but be careful what you adjust....your dvd player will dislike incorrect settings!!
The only permanent cure is to replace the optical block with a new one-if that is the cause of your problem.How old is your dvd player??
